yum安装nginx-蒲公英云

1、镜像配置（可以略过）

# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#

baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
        http://mirrors.aliyuncs.com/centos/$releasever/os/$basearch/

2、命令

yum install -y nginx

3、安装成功

4、配置文件

路径：

cd /etc/nginx

编辑文件

nginx.conf

user root;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/nginx/README.dynamic.
#include /usr/share/nginx/modules/*.conf;
events {
    worker_connections 1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    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  logs/access.log  main;
    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    gzip  on;
    include /etc/nginx/conf.d/*.conf;
}

具体的server配置

cd /etc/nginx/conf.d

对应的配置

如 vim xxxx.conf

server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;
        # Load configuration files for the default server block.
    location /{
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404;
        proxy_set_header     Host               $host;
        proxy_set_header     X-Real-IP          $remote_addr;
        proxy_set_header     X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header     Cookie             "$http_cookie";
        proxy_hide_header    X-Powered-By;
        proxy_hide_header    X-AspNet-Version;
        proxy_hide_header    X-AspNetMvc-Version;
        proxy_pass           http://127.0.0.1:8080;
    }
        error_page 404 /404.html;
        location = /404.html {
    }
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}

5、启动

启动命令

nginx -c /etc/nginx/nginx.conf

查看进程

ps -ef | grep nginx

启动成功

重新加载

nginx -s reload

6、设置开机启动

编辑或者新建文件，如果有就不需要了。

vim /lib/systemd/system/nginx.service

加入以下内容：
