## 编译和安装  ##

make && make install

## **设置 /usr/local/nginx/conf/nginx.conf, 部分如下:** ##

#user  nobody;
     user nginx nginx;
     worker_processes  1;
    
     #crit
     error_log logs/error.log crit;
     #error_log  logs/error.log;
     #error_log  logs/error.log  notice;
     #error_log  logs/error.log  info;
    
     pid        /var/run/nginx.pid;
    
    
     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;
    
         sendfile        on;
         #tcp_nopush     on;
    
         #keepalive_timeout  0;
         keepalive_timeout  65;
    
         gzip  on;
         #max upload file size
         client_max_body_size 6m;
    
    ......

##       **设置自动启动服务** ##

在/usr/lib/systemd/system/目录下面新建一个*nginx.service*文件  
注意: nginx 安装的路径为 /usr/local/nginx

[Unit]
    Description=nginx - high performance web server
    Documentation=http://nginx.org/en/docs
    After=network.target remote-fs.target nss-lookup.target
    
    [Service]
    Type=forking
    PIDFile=/var/run/nginx.pid
    #/usr/local/nginx/sbin/nginx
    ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
    ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
    
    ExecReload=/usr/local/nginx/sbin/nginx -c reload /usr/local/nginx/conf/nginx.conf
    ExecStop=/usr/local/nginx/sbin/nginx quit
    #ExecReload=/bin/kill -s HUP $MAINPID
    #ExecStop=/bin/kill -s QUIT $MAINPID
    KillSignal=SIGQUIT
    TimeoutStopSec=5
    KillMode=process
    PrivateTmp=true
    
    [Install]
    WantedBy=multi-user.target

--------------------

另:   
service nginx start 启动时抛如下错误

[root@aerchi-centos system]# service nginx restart
    Redirecting to /bin/systemctl restart nginx.service
    Job for nginx.service failed because the control process exited with error code.
    See "systemctl status nginx.service" and "journalctl -xe" for details.

出错原因:

[root@aerchi-centos system]# systemctl status nginx.service
    ● nginx.service - nginx - high performance web server
       Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)

    Sep 29 16:04:35 aerchi-centos systemd[1]: Failed to start nginx - high performance web server.

解决方法:

出现以上错误 , 请检查  nginx.service 里(nginx 安装路径是否正确)  
ExecStartPre=**/usr/local/nginx**/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf  
ExecStart=**/usr/local/nginx**/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

之后, 再次运行 'systemctl daemon-reload' 来重新加载
