1.将阿里云 下载下来的nginx(key/pem) 放在nignx包下面(重新创建一个文件夹/cer) expired:三月换一次
2.更新nignx config.conf 配置 配置如下:
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.

include /usr/share/nginx/modules/*.conf;

events {
worker_connections 1024;
}

http {
log_format main '$remote_addr - $remote_user [$time_local] “request" ' 'status $body_bytes_sent "$http_referer” ’
‘“$http_user_agent" "$http_x_forwarded_for”’;

access_log  /var/log/nginx/access.log  main;

sendfile            on;
tcp_nopush          on;
tcp_nodelay         on;
keepalive_timeout   65;
types_hash_max_size 4096;

include             /etc/nginx/mime.types;
default_type        application/octet-stream;

include /etc/nginx/conf.d/*.conf;

server {
    listen       443 ssl;
    server_name  www.wxapp.samlin.com.cn;
    root         /usr/share/nginx/html;

    ssl_certificate cert/www.wxapp.samlin.com.cn.pem;
    ssl_certificate_key cert/www.wxapp.samlin.com.cn.key;
    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout  10m;
    ssl_ciphers PROFILE=SYSTEM;
    ssl_prefer_server_ciphers on;

    include /etc/nginx/default.d/*.conf;

    location / {   
        proxy_pass http://www.wxapp.samlin.com.cn:8090/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }        
}


server {
    listen 80;
    server_name www.wxapp.samlin.com.cn;
