Nginx 在 Linux 上的安装和配置

一.安装

yum install nginx -y

如果提示 No package nginx available，安装一个源即可

yum install epel-release -y

 

二.配置反向代理（配置文件一般在 /etc/nginx/nginx.conf）

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
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       80;
        server_name  ip或域名;
        location /  {
                     proxy_pass http://localhost:5000;
                     proxy_set_header Host $host;
                     proxy_set_header X-Real-IP $remote_addr;
                     proxy_set_header REMOTE-HOST $remote_addr;
                     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

        error_page 404 /404.html;
        location = /404.html {
        }

        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
        }
    }

# Settings for a TLS enabled server.
#
#    server {
#        listen       443 ssl http2;
#        listen       [::]:443 ssl http2;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        ssl_certificate "/etc/pki/nginx/server.crt";
#        ssl_certificate_key "/etc/pki/nginx/private/server.key";
#        ssl_session_cache shared:SSL:1m;
#        ssl_session_timeout  10m;
#        ssl_ciphers HIGH:!aNULL:!MD5;
#        ssl_prefer_server_ciphers on;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }
}

 

三.启动或重启

nginx
或
nginx -s reload

如果出现nginx: [error] open() “/var/run/nginx.pid” failed (2: No such file or directory) 错误，执行下面命令后，在重新读取配置文件即可

sudo nginx -c /etc/nginx/nginx.conf

 

四.配置开机启动
创建 nginx.service 文件，并放入 usr/lib/systemd/system/ ，内容如下

[Unit]  
Description=nginx  
After=network.target  
   
[Service]  
Type=forking  
ExecStart=/usr/local/nginx/sbin/nginx 
ExecReload=/usr/local/nginx/sbin/nginx -s reload  
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true  
   
[Install]  
WantedBy=multi-user.target

然后设置开机自动启动

systemctl enable nginx.service
