Nginx 配置 SSL证书

成功配置SSL证书后，您将能够通过HTTPS加密通道安全访问Nginx服务器。

一、准备材料

SSL证书绑定的域名已完成DNS解析，即您的域名与主机IP地址相互映射。您可以通过DNS验证证书工具，检测域名DNS解析是否生效。具体操作：
【1】登录数字证书管理服务控制台。
【2】在左侧导航栏，选择证书工具 > DNS验证。
【3】在DNS页签，选择您域名所在的运营商和地域，并输入您的网站域名，单击立即检测。DNS检测结果列表中的解析结果与您在解析配置中的记录值一致时，代表解析正常生效。

已通过数字证书管理服务控制台签发证书。

已在Web服务器开放443端口（HTTPS通信的标准端口）： 如果您使用的是阿里云ECS服务器，请确保已经在安全组规则入方向添加TCP 443端口和TCP 80端口。

二、下载SSL证书

【1】登录数字证书管理服务控制台
【2】在左侧导航栏，单击SSL证书。
【3】在SSL证书页面，定位到目标证书，在操作列，单击下载。
【4】在服务器类型为Nginx的操作列，单击下载。

【5】解压缩已下载的SSL证书压缩包：根据您在提交证书申请时选择的CSR生成方式，解压缩获得的文件不同。证书文件（PEM格式）： Nginx支持安装PEM格式的文件，PEM格式的证书文件是采用Base64编码的文本文件，且包含完整证书链。解压后，该文件以证书ID_证书绑定域名命名。私钥文件（KEY格式）： 默认以证书绑定域名命名。

三、安装Nginx

已安装的可以忽略该步骤

直接在Linux服务上使用wget命令把Nginx安装包下载到/usr/local/目录中

wget -c http://nginx.org/download/nginx-1.24.0.tar.gz

安装Nginx相关依赖

#安装nginx所需要的依赖包
yum install -y gcc-c++	zlib zlib-devel	openssl openssl-devel pcre pcre-devel

安装Nginx：解压Nginx安装包

#解压安装包
tar -zxvf nginx-1.24.0.tar.gz

进入解压之后的Nginx目录下：

#进入nginx目录
cd /usr/local/nginx

执行配置脚本，--prefix是指定安装目录

# 编译，执行配置: 考虑到后续安装ssl证书 添加两个模块
./configure --with-http_stub_status_module --with-http_ssl_module

编译安装

#对nginx编译和安装
make & make install

启动Nginx服务：安装好的Nginx服务在/usr/local/nginx下：

[root@xxx sbin]# pwd
/usr/local/nginx/sbin# 启动
./nginx# 重启
./nginx -s reload# 关闭
./nginx -s stop# 或者，指定配置文件启动
./nginx -c /usr/local/nginx/conf/nginx.conf

查看Nginx是否启动成功

[root@xxx sbin]# ps -ef | grep nginx
root      1399  1320  0 Jan27 ?        00:00:00 nginx: master process nginx -g daemon off;
root      1574  1399  0 Jan27 ?        00:00:00 nginx: worker process
root      1575  1399  0 Jan27 ?        00:00:00 nginx: worker process
root     20336     1  0 21:21 ?        00:00:00 nginx: master process ./nginx
nobody   20337 20336  0 21:21 ?        00:00:00 nginx: worker process
root     20366 13337  0 21:21 pts/3    00:00:00 grep --color=auto nginx

设置nginx的开机启动

vim /etc/rc.local
文本底部追加
/usr/local/nginx/sbin/nginx

编辑安装目录conf下的nginx.conf文件：

server {listen       80;server_name  yourdomain.com; # 修改为你自己的域名或IP地址location / {root   /path/to/your/vuepress/site; # 修改为你的VuePress站点路径，也就是vue npm run build 打包后放置静态文件dist的路径index  index.html index.htm;try_files $uri $uri/ /index.html;}
}

三、在Nginx服务器安装证书

【1】执行以下命令，在Nginx的conf目录下创建一个cert用于存放证书的目录。

[root@iZuf65h6i43ltlzhqolumyZ conf]# cd /usr/local/nginx/conf  --进入Nginx默认配置文件目录。该目录为手动编译安装Nginx时的默认目录，如果您修改过默认安装目录或使用其他方式安装，请根据实际配置调整。
[root@iZuf65h6i43ltlzhqolumyZ conf]# cd cert/
[root@iZuf65h6i43ltlzhqolumyZ cert]# ll
total 12
-rw-r--r-- 1 root root 1679 Feb  8 18:29 it-blog-cn.com.key
-rw-r--r-- 1 root root 4772 Feb  8 18:29 it-blog-cn.com.pem

.pem：证书文件。PEM文件的扩展名为CRT格式。
.key：证书的密钥文件。申请证书时如果未选择自动创建CRS，则下载的证书文件压缩包中不会包含.key文件，需要您将自己手动常见的私钥文件拷贝到cert目录下。

【2】更改nginx.conf设置vim nginx.conf找到server块，将HTTPS server部分注释去掉【从需要删除的部分开始安装ctrl+v，然后ctrl+d删除】并修改：

    # HTTPS server# 将 it-blog-cn.com 修改为自己的域名server {listen       443 ssl;server_name  it-blog-cn.com;ssl_certificate      /usr/local/nginx/conf/cert/it-blog-cn.com.pem;ssl_certificate_key  /usr/local/nginx/conf/cert/it-blog-cn.com.key;ssl_session_cache    shared:SSL:1m;ssl_session_timeout  5m;ssl_ciphers  HIGH:!aNULL:!MD5;ssl_prefer_server_ciphers  on;location / {root   html;index  index.html index.htm;}}

【3】通过nginx -t校验nginx文件语法。如果提示找不到证书文件，说明文件路径配置的不正确。

[root@iZuf65h6i43ltlzhqolumyZ conf]# ../sbin/nginx -t
nginx: [emerg] cannot load certificate "/usr/local/nginx/conf/it-blog-cn.com.pem": BIO_new_file() failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/usr/local/nginx/conf/it-blog-cn.com.pem','r') error:2006D080:BIO routines:BIO_new_file:no such file)

如果提示success，表示校验成功

[root@iZuf65h6i43ltlzhqolumyZ conf]# ../sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

【4】通过nginx -s reload重启nginx
【5】检查443端口

[root@iZuf65h6i43ltlzhqolumyZ conf]# netstat -ntlp lgrep 443
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      20336/nginx: master 

【5】查询防火墙的状态

[root@iZuf65h6i43ltlzhqolumyZ conf]# firewall -cmd --state
running

查询防火墙是否放开了443端口，结果显示只有80端口

[root@iZuf65h6i43ltlzhqolumyZ conf]# firewall -cmd --list-prots
80/tcp

打开443端口，完成后执行reload命令

[root@iZuf65h6i43ltlzhqolumyZ conf]# firewall -cmd --zone=public --add-prot=443/toc --permanent
success
[root@iZuf65h6i43ltlzhqolumyZ conf]# firewall -cmd --reload
success
[root@iZuf65h6i43ltlzhqolumyZ conf]# firewall -cmd --list-ports
80/tcp 443/tcp

【6】执行echo命令在服务器上模拟客户端，将测试命令中的it-blog-cn更换为自己的域名。检查本地443端口加载的HTTPS服务以及证书是否正常。如下出现SSL-Session表示HTTPS服务正常运行，服务器配置的SSL证书是可用的。如果提示connect:errno=111表示没有服务，建议检查Nginx是否启动。

[root@iZuf65h6i43ltlzhqolumyZ conf]# echo | openssl s_client -connect 127.0.0.1:443 -servername it-blog.cn 2>/dev/null
CONNECTED(00000003)

四、更新ECS安全组

放行TCP协议443端口的入方向请求，并在浏览器端通过HTTPS访问域名成功。

五、HTTP 强制跳转 HTTPS

修改nginx.conf

[root@iZuf65h6i43ltlzhqolumyZ conf]# vim nginx.conf

在80端口下方添加rewrite ^(.*)$ https://$host$1;，并通过nginx -t校验语法，并通过nginx -s reload重新启动nginx

server {listen       80;server_name  localhost;rewrite ^(.*)$ https://$host$1;

六、Nginx 配置文件

nginx.conf配置全文

#user  nobody;worker_processes  1;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;pid        logs/nginx.pid;events {worker_connections  1024;
