Correct way to install SSL certificate in nginx

前提条件:

已经生成了以下文件:

domain.com.crt (域名证书) 有的证书可能是cer 或 pem 或其他后缀名,都可以

domain.com.key (私钥文件)

(相关教程:nginx教程

配置Nginx

找到站点的配置文件,在server中添加443端口监听和证书文件引用

server { listen 80; #监听443端口(必须) listen 443 ssl; server_name domain.com www.domain.com; index index.html index.php index.htm; root /www/wwwroot/domain.com; #引用证书(必须,放在conf/ssl目录下可以用相对路径,其他位置用绝对路径) ssl_certificate ssl/domain.com.crt; ssl_certificate_key ssl/domain.com.key; #协议优化(可选,优化https协议,增加安全性) ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE; ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; #其他的配置信息··· }
Copy after login

以上为最基本的配置,其他参数请根据生产环境需要添加

安装后重启nginx使其生效

如果重启nginx

失败使用如下命令检测nginx是否支持SSL

nginx -V
Copy after login

如果有显示 –with-http_ssl_module 表示已编译openssl,支持安装ssl,仔细检查配置文件
如果没有安装请下载nginx源码重新编译

./configure --with-http_stub_status_module --with-http_ssl_module make && make install
Copy after login

强制跳转HTTPS

在配置文件中添加跳转代码

server { #站点和SSL的配置信息··· #自动跳转到HTTPS(可选,和下面的部分域名跳转不能同时使用) if ($server_port = 80){ rewrite ^(/.*)$ https://$host$1 permanent; } #绑定域名较多,只让部分域名跳转(根据情况选用,和上面的全部跳转不能同时使用) set $redirect_https 1; if ($server_port = 80) { set $redirect_https "${redirect_https}2"; } if ($http_host = 'abc.com') { set $redirect_https "${redirect_https}3"; } if ($http_host = 'cde.com') { set $redirect_https "${redirect_https}3"; } if ($redirect_https = "123") { #当前域名跳转 rewrite ^(.*)$ https://$host$1 permanent; #可以跳转到指定的域名 #rewrite ^(.*)$ https://www.abcde.com$1 permanent; } }
Copy after login
