Nginx 配置

创建 Nginx 运行使用的用户 www

[root@bogon conf]# /usr/sbin/groupadd www 
[root@bogon conf]# /usr/sbin/useradd -g www www

配置nginx.conf

• 将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容配置nginx.conf ，将/usr/local/webserver/nginx/conf/nginx.conf替换为以下内容:

user www www;
worker_processes 2; #设置值和CPU核心数一致
error_log /usr/local/webserver/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll;
  worker_connections 65535;
}

  include mime.types;
  default_type application/octet-stream;
  log_format main  '$remote_addr - $remote_user [$time_local] "$request" '
               '$status $body_bytes_sent "$http_referer" '

  {

    root /usr/local/webserver/nginx/html;#站点目录
    location /aaa {
      proxy_pass http://127.0.0.1:8080/aaa;
    }
    location /abcd {
      proxy_pass http://127.0.0.1:8081/abcd;
    }
    location /yiwu {
     proxy_pass http://127.0.0.1:8081/yiwu;
    }
      location ~ .*\.(php|php5)?$
    {

      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
    {

    access_log off;
  }
  server {
    listen 443 ssl;
    server_name localhost;
    ssl on;
    root html;
    index index.html index.htm;

    ssl_prefer_server_ciphers on;
    location / {
        root html;
        index index.html index.htm;
    }
    location /aaa {
       proxy_pass http://127.0.0.1:8080/aaa;
    }
    location /abcd {
       proxy_pass http://127.0.0.1:8081/abcd;
    }
  }
}

• 在conf目录新建cert文件夹，将证书文件（阿里云免费证书：pem，key）放置cert，并且加入一个配置server：（这个server是https的配置，原先的server是对于http的配置）

server {
    listen 443 ssl;
    server_name localhost;
    ssl on;
    root html;
    index index.html index.htm;
    ssl_certificate   cert/214335641040602.pem;
    ssl_certificate_key  cert/214335641040602.key;
    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 / {
        root html;
        index index.html index.htm;
    }
    location /bjjc {
       proxy_pass http://127.0.0.1:8080/bjjc;
    }
    location /yiwu {
       proxy_pass http://127.0.0.1:8081/yiwu;
    }
  }

检查配置文件ngnix.conf的正确性命令

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx -t

启动 Nginx

[root@bogon conf]# /usr/local/webserver/nginx/sbin/nginx

启动后可以根据ip访问成功！

• Nginx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

安装后启动报错，原因是tomcat80端口冲突
