Nginx安装配置，支持http以及https

**一、Nginx安装**

可参考：[Nginx 安装配置][Nginx]

如果yum安装失败，可从这个地方[\*\*\*][Link 1]下载相关rpm包，直接执行install.sh安装即可

**二、配置http**

修改配置文件nginx.conf，安装上边的步骤安装，应该是在/usr/local/webserver/nginx/conf这个目录下

修改配置文件第一个server的location值如下，并在上边加入upstream backend，这样就可以配置多个webserver

upstream backend {
        server 192.168.1.231:10001;
        server 192.168.1.232:10001;
        server 192.168.1.233:10001;
        server 192.168.1.234:10001;
        server 192.168.1.235:10001;
    }
    
    location / {
        proxy_redirect off;
        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_pass http://backend;
    }

**三、配置https**

1.配置https，首先要生成SSL证书

# 1、首先，在安装目录下新建ssl文件夹，进入该目录，例如：
    mkdir /usr/local/webserver/nginx/ssl
    cd /usr/local/webserver/nginx/ssl
    
    # 2、创建服务器私钥，命令会让你输入一个口令：
    openssl genrsa -des3 -out server.key 1024
    
    # 3、创建签名请求的证书（CSR）：
    openssl req -new -key server.key -out server.csr
    
    # 4、在加载SSL支持的Nginx并使用上述私钥时除去必须的口令：
    cp server.key server.key.org
    openssl rsa -in server.key.org -out server.key
    
    # 5、最后标记证书使用上述私钥和CSR：
    openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

2.修改nginx.conf配置文件

将配置文件最后边的HTTPS server的注释放开，修改值如下，然后在前边加入upstream backend内容

upstream backend {
        server 192.168.1.231:10001;
        server 192.168.1.232:10001;
        server 192.168.1.233:10001;
        server 192.168.1.234:10001;
        server 192.168.1.235:10001;
    }
    
    # HTTPS server
    #
    server {
       listen       443 ssl;
       server_name  localhost;
    
       ssl_certificate      /usr/local/webserver/nginx/ssl/server.crt;
       ssl_certificate_key  /usr/local/webserver/nginx/ssl/server.key;
    
       ssl_session_cache    shared:SSL:1m;
       ssl_session_timeout  5m;
    
       ssl_ciphers  HIGH:!aNULL:!MD5;
       ssl_prefer_server_ciphers  on;
    
       location / {
                proxy_redirect off;
                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_pass https://backend;
       }
    }

** 四、配置完成后启动server**

# 进入目录/usr/local/webserver/nginx/sbin
    cd /usr/local/webserver/nginx/sbin
    # 启动
    ./nginx -t -c /usr/local/webserver/nginx/conf/nginx.conf
    
    # 其他命令
    /usr/local/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
    /usr/local/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx
    /usr/local/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx
