三、问题
一、理论
1.LNMP架构
（1）架构
搭建一个lnmp环境，需要涉及到两个目录结构和一个yml配置文件。一个是Dockerfile配置的目录结构，另一个是最终lnmp运行的目录结构。Dockerfile配置目录主要存放Dockerfile构建脚本和一些配置文件，lnmp运行目录主要存放程序运行产生的一些数据，比如mysql数据等。
以下是此次Dockerfile配置的目录结构，包括了nginx、php、mysql的配置文件。
[root@localhost opt]# tree /opt/compose_lnmp/ -L 2
/opt/compose_lnmp/
├── docker-compose.yml

2.背景
（1）项目环境
公司在实际的生产环境中，需要使用 Docker 技术在一台主机上创建 LNMP 服务并运行 Wordpress 网站平台。然后对此服务使用docker-compose管理工作。
（2）所有安装包下载
nginx:
nginx：下载
MySQL:
MySQL ：： MySQL 下载
PHP:
PHP： 下载
（3）任务需求
使用Docker构建LNMP环境并运行Wordpress网站平台。
为了方便运维和统一管理使用进行docker-compose编排
将所有容器进行快照，然后将Docker镜像打包成tar包备份到本地。
把docker-compose.yml 复制到文档中
3.Dockerfile部署LNMP
（1）关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
setenforce 0Docker各组件的ip为：
| 容器 | 操作系统 | IP地址 | 主要软件 |
| nginx | CentOS 7 | 172.20.0.10 | Docker-Nginx |
| mysql | CentOS 7 | 172.20.0.20 | Docker-Mysql |
| php | CentOS 7 | 172.20.0.30 | Docker-php |
此实验所需的软件有：
mysql-boost-5.7.20.tar.gz
nginx-1.12.0.tar.gz
php-7.1.10.tar.bz2
wordpress-4.9.4-zh_CN.tar.gz

(4)准备Dockerfile需要的PHP配置文件
①配置php.ini文件
vim php.ini[PHP];;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; PHP's initialization file, generally called php.ini, is responsible for
; configuring many of the aspects of PHP's behavior.; PHP attempts to find and load this configuration from a number of locations.
; The following is a summary of its search order:
; 1. SAPI module specific location.
; 2. The PHPRC environment variable. (As of PHP 5.2.0)
; 3. A number of predefined registry keys on Windows (As of PHP 5.2.0)
; 4. Current working directory (except CLI)
; 5. The web server's directory (for SAPI modules), or directory of PHP
; (otherwise in Windows)
; 6. The directory from the --with-config-file-path compile time option, or the
; Windows directory (C:\windows or C:\winnt)
; See the PHP docs for more specific information.
; http://php.net/configuration.file; The syntax of the file is extremely simple. Whitespace and lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.; Directives following the section heading [PATH=/www/mysite] only
; apply to PHP files in the /www/mysite directory. Directives
; following the section heading [HOST=www.example.com] only apply to
; PHP files served from www.example.com. Directives set in these
; special sections cannot be overridden by user-defined INI files or
; at runtime. Currently, [PATH=] and [HOST=] sections only work under
; CGI/FastCGI.
; http://php.net/ini.sections; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
; Directives are variables used to configure PHP or PHP extensions.
; There is no name validation. If PHP can't find an expected
; directive because it is not set or is mistyped, a default value will be used.; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), a quoted string ("bar"), or a reference to a
; previously set variable or directive (e.g. ${foo}); Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; ^ bitwise XOR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:; foo = ; sets foo to an empty string
; foo = None ; sets foo to an empty string
; foo = "None" ; sets foo to the string 'None'; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; PHP comes packaged with two INI files. One that is recommended to be used
; in production environments and one that is recommended to be used in
; development environments.; php.ini-production contains settings which hold security, performance and
; best practices at its core. But please be aware, these settings may break
; compatibility with older or less security conscience applications. We
; recommending using the production ini in production and testing environments.; php.ini-development is very similar to its production variant, except it is
; much more verbose when it comes to errors. We recommend using the
; development version only in development environments, as errors shown to
; application users can inadvertently leak otherwise secure information.; This is php.ini-development INI file.;;;;;;;;;;;;;;;;;;;
; Quick Reference ;
;;;;;;;;;;;;;;;;;;;
; The following are all the settings which are different in either the production
; or development versions of the INIs with respect to PHP's default behavior.
; Please see the actual settings later in the document for more details as to why
; we recommend these changes in PHP's behavior.; display_errors

; http://php.net/engine
engine = On; This directive determines whether or not PHP will recognize code between
; <? and ?> tags as PHP source which should be processed as such. It is
; generally recommended that <?php and ?> should be used and that this feature
; should be disabled, as enabling it may result in issues when generating XML
; documents, however this remains supported for backward compatibility reasons.
; Note that this directive does not control the <?= shorthand tag, which can be
; used regardless of this directive.
; Default Value: On

; http://php.net/precision
precision = 14; Output buffering is a mechanism for controlling how much output data
; (excluding headers and cookies) PHP should keep internally before pushing that
; data to the client. If your application's output exceeds this setting, PHP
; will send that data in chunks of roughly the size you specify.
; Turning on this setting and managing its maximum buffer size can yield some
; interesting side-effects depending on your application and web server.
; You may be able to send headers and cookies after you've already sent output
; through print or echo. You also may see performance benefits if your server is
; emitting less packets due to buffered output versus PHP streaming the output
; as it gets it. On production servers, 4096 bytes is a good setting for performance
; reasons.
; Note: Output buffering can also be controlled via Output Buffering Control
; functions.
; Possible Values:
; On = Enabled and buffer is unlimited. (Use with caution)
; Off = Disabled
; Integer = Enables the buffer and sets its maximum size in bytes.
; Note: This directive is hardcoded to Off for the CLI SAPI

; http://php.net/output-buffering
output_buffering = 4096; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to "mb_output_handler", character

; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
; is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
; and you cannot use both "ob_gzhandler" and "zlib.output_compression".

;url_rewriter.hosts; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary due to nature of compression. PHP
; outputs chunks that are few hundreds bytes each as a result of
; compression. If you prefer a larger chunk size for better
; performance, enable output_buffering in addition.
; Note: You need to use zlib.output_handler instead of the standard
; output_handler, or otherwise the output will be corrupted.

; http://php.net/zlib.output-handler
;zlib.output_handler =; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block. This is equivalent to calling the

; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; This directive informs PHP of which errors, warnings and notices you would like
; it to take action for. The recommended way of setting values for this
; directive is through the use of the error level constants and bitwise
; operators. The error level constants are below here for convenience as well as
; some common settings and their meanings.
; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
; those related to E_NOTICE and E_STRICT, which together cover best practices and
; recommended coding standards in PHP. For performance reasons, this is the
; recommend error reporting setting. Your production server shouldn't be wasting
; resources complaining about best practices and coding standards. That's what
; development servers and development settings are for.
; Note: The php.ini-development file has this setting as E_ALL. This
; means it pretty much reports everything which is exactly what you want during
; development and early testing.
;
; Error Level Constants:
; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
; E_ERROR - fatal run-time errors
; E_RECOVERABLE_ERROR - almost fatal run-time errors
; E_WARNING - run-time warnings (non-fatal errors)
; E_PARSE - compile-time parse errors
; E_NOTICE - run-time notices (these are warnings which often result
; from a bug in your code, but it's possible that it was
; intentional (e.g., using an uninitialized variable and
; relying on the fact it is automatically initialized to an

; http://php.net/error-reporting
error_reporting = E_ALL; This directive controls whether or not and where PHP will output errors,
; notices and warnings too. Error output is very useful during development, but
; it could be very dangerous in production environments. Depending on the code
; which is triggering the error, sensitive information could potentially leak
; out of your application such as database usernames and passwords or worse.
; For production environments, we recommend logging errors rather than
; sending them to STDOUT.
; Possible Values:
; Off = Do not display any errors
; stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
; On or stdout = Display errors to STDOUT
; Default Value: On
; Development Value: On
; Production Value: Off
; http://php.net/display-errors
display_errors = On; The display of errors which occur during PHP's startup sequence are handled
; separately from display_errors. PHP's default behavior is to suppress those
; errors from clients. Turning the display of startup errors on can be useful in
; debugging configuration problems. We strongly recommend you
; set this to 'off' for production servers.
; Default Value: Off
; Development Value: On
; Production Value: Off
; http://php.net/display-startup-errors
display_startup_errors = On; Besides displaying errors, PHP can also log errors to locations such as a
; server-specific log, STDERR, or a location specified by the error_log
; directive found below. While errors should not be displayed on productions
; servers they should still be monitored and logging is a great way to do that.
; Default Value: Off
; Development Value: On
; Production Value: On
; http://php.net/log-errors
log_errors = On; Set maximum length of log_errors. In error_log information about the source is
; added. The default is 1024 and 0 allows to not apply any maximum length at all.

; is On you will not log errors with repeated messages from different files or
; source lines.
; http://php.net/ignore-repeated-source
ignore_repeated_source = Off; If this parameter is set to Off, then memory leaks will not be shown (on
; stdout or in the log). This has only effect in a debug compile, and if
; error reporting includes E_WARNING in the allowed list
; http://php.net/report-memleaks
report_memleaks = On; This setting is on by default.
;report_zend_debug = 0; Store the last error/warning message in $php_errormsg (boolean). Setting this value

; http://php.net/html-errors
html_errors = On; If html_errors is set to On *and* docref_root is not empty, then PHP
; produces clickable error messages that direct to a page describing the error

; You can download a copy of the PHP manual from http://php.net/docs
; and change docref_root to the base URL of your local copy including the
; leading '/'. You must also specify the file extension being used including
; the dot. PHP's default behavior is to leave these settings empty, in which
; case no links to documentation are generated.
; Note: Never use this feature for production boxes.
; http://php.net/docref-root

;docref_root = "/phpmanual/"; http://php.net/docref-ext

; http://php.net/arg-separator.input
; Example:
;arg_separator.input = ";&"; This directive determines which super global arrays are registered when PHP
; starts up. G,P,C,E & S are abbreviations for the following respective super
; globals: GET, POST, COOKIE, ENV and SERVER. There is a performance penalty
; paid for the registration of these arrays and because ENV is not as commonly
; used as the others, ENV is not recommended on productions servers. You
; can still get access to the environment variables through getenv() should you
; need to.
; Default Value: "EGPCS"
; Development Value: "GPCS"
; Production Value: "GPCS";
; http://php.net/variables-order
variables_order = "GPCS"; This directive determines which super global data (G,P & C) should be
; registered into the super global array REQUEST. If so, it also determines
; the order in which that data is registered. The values for this directive
; are specified in the same manner as the variables_order directive,
; EXCEPT one. Leaving this value empty will cause PHP to use the value set
; in the variables_order directive. It does not mean it will leave the super
; globals array REQUEST empty.
; Default Value: None
; Development Value: "GP"
; Production Value: "GP"
; http://php.net/request-order
request_order = "GP"; This directive determines whether PHP registers $argv & $argc each time it
; runs. $argv contains an array of all the arguments passed to PHP when a script
; is invoked. $argc contains an integer representing the number of arguments
; that were passed when the script was invoked. These arrays are extremely
; useful when running scripts from the command line. When this directive is
; enabled, registering these variables consumes CPU cycles and memory each time
; a script is executed. For performance reasons, this feature should be disabled
; on production servers.
; Note: This directive is hardcoded to On for the CLI SAPI
; Default Value: On
; Development Value: Off
; Production Value: Off
; http://php.net/register-argc-argv
register_argc_argv = Off; When enabled, the ENV, REQUEST and SERVER variables are created when they're
; first used (Just In Time) instead of when the script starts. If these
; variables are not used within a script, having this directive on will result
; in a performance gain. The PHP directive register_argc_argv must be disabled
; for this directive to have any affect.
; http://php.net/auto-globals-jit
auto_globals_jit = On; Whether PHP will read the POST data.
; This option is enabled by default.
; Most likely, you won't want to disable this option globally. It causes $_POST

; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
; http://www.foo.bar/status
; http://www.foo.bar/status?json
; http://www.foo.bar/status?html
; http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
; http://www.foo.bar/status?full
; http://www.foo.bar/status?json&full
; http://www.foo.bar/status?html&full
; http://www.foo.bar/status?xml&full

; start since - the number of seconds since the process has started;
; requests - the number of requests the process has served;
; request duration - the duration in µs of the requests;
; request method - the request method (GET, POST, ...);
; request URI - the request URI with the query string;
; content length - the content length of the request (only with POST);
; user - the user (PHP_AUTH_USER) (or '-' if not set);
; script - the main script called (or '-' if not set);
; last request cpu - the %cpu the last request consumed
; it's always 0 if the process is not in Idle state
; because CPU calculation is done when the request
; processing has terminated;
; last request memory - the max amount of memory the last request consumed
; it's always 0 if the process is not in Idle state
; because memory calculation is done when the request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related to
; the current request being served.
; Example output:

10.浏览器访问
http://192.168.204.141:1315/wordpress/wp-admin/setup-config.php11.将运行中的 docker容器保存为 docker 镜像并保存到本地tar包
方法
1、docker commit <容器id> <镜像名>:<tag> ---- 将容器保存成镜像，tag比如说latest保存后 docker images 便可以看到镜像2、docker save -o <tar包名>.tar <镜像名>:<tag> ---- 将镜像保存为.tar文件，默认保存在当前目录
从 tar 包导入docker镜像
1、docker load -i <tar包名>.tar ---- 从 tar 包导入镜像导入镜像后，通过 docker images 便可看到导入的镜像。2、docker run -itd -p <本地端口>:<容器端口> <镜像名>:<tag> ---- 通过镜像起容器
案例「仅保存到tar包」
