nginx添加ssl证书升级为https(免费证书)
琢磨着想弄一个小程序玩玩,所以根据小程序接口要求,必须要有https,遂加ssl之
免费证书自己可以百度,我选择了certbot,阿里云也有免费证书,这个随便选择,重要的是实现过程。
1、证书获取
注
根据网站上面提示步骤一一实现,不过我在第五步选择了下面的方式,因为我nginx是自己源码安装的
注
注意一下生成的证书位置
2、nginx修改
server { listen 443 ssl; server_name www.***.com; root /www/****/****; index index.html index.htm index.php; ssl_certificate /etc/letsencrypt/live/www.***.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/www.***.com/privkey.pem; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_prefer_server_ciphers on; location ~* \.(png|jpg|jpeg|gif|css|js|html)$ { try_files $uri $uri/ =404; } location / { try_files $uri $uri/ /index.php$is_args$query_string; } location ~ \.php$ { try_files $uri =404; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { listen 80; server_name www.***.com; rewrite ^(.*)$ https://$host$1 permanent; }
3、重启nginx测试网站,很nice
4、坑点tip
nginx: [error] invalid PID number "" in "/usr/local/nginx/logs/nginx.pid
nginx启动没有指定配置文件,启动时添加参数即可
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
tip
[warn] the "ssl" directive is deprecated, use the "listen ... ssl" directive instead
写法问题,网上找到的很多ssl写法都是:
listen 443; ssl on;
正确写法:
listen 443 ssl;
tip
nginx: [emerg] unknown directive "ssl" in /usr/local/nginx/conf/vhosts/testssl.conf:4
nginx缺少ssl模块
解决方法:
① 到源码目录添加ssl模块 ./configure --with-http_ssl_module 注
如果需要openssl则安装yum -y install openssl openssl-devel,安装完毕再./configure
② make编译
③ 之前的文件备份:mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.pre
④ 新文件引入:cp objs/nginx /usr/local/nginx/sbin/nginx
⑤ 查看是否安装./sbin/nginx -V 注
v是大写
⑥ 重启nginx查看
