Centos7之Nginx

1、安装

　　下载RPM:　wget http://nginx.org/download/nginx-1.16.0.tar.gz

　　解压：tar -zxf nginx-1.16.0.tar.gz

　　安装：

　　　　cd nginx-1.16.0

　　　　./configure
　　　　make && make install

2、安装成功后nginx的几个默认目录

　　执行目录：/usr/sbin/nginx

　　模块所在目录：/usr/lib64/nginx/modules

　　配置所在目录：/etc/nginx/

　　默认站点目录：/usr/share/nginx/html

　　主要配置文件：/etc/nginx/nginx.conf 指向：/etc/nginx/conf.d/default.conf
　　PID目录：/var/run/nginx.pid
　　错误日志：/var/log/nginx/error.log
　　访问日志：/var/log/nginx/access.log

3、查看nginx状态

　　输入命令：systemctl status nginx.service

 [root@N37012 ~]# systemctl status nginx.service
 ● nginx.service - nginx
    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
    Active: failed (Result: exit-code) since 日 -- :: CST; 15min ago
   Process:  ExecStop=/usr/local/nginx/sbin/nginx quit (code=exited, status=/FAILURE)
  Main PID:  (code=exited, status=/SUCCESS)

 5月  :: N37012 systemd[]: Starting nginx...
 5月  :: N37012 systemd[]: Started nginx.
 5月  :: N37012 systemd[]: Stopping nginx...
 5月  :: N37012 nginx[]: nginx: invalid option: "quit"
 5月  :: N37012 systemd[]: nginx.service: control process exited, code=exited status=
 5月  :: N37012 systemd[]: Stopped nginx.
 5月  :: N37012 systemd[]: Unit nginx.service entered failed state.
 5月  :: N37012 systemd[]: nginx.service failed.
 [root@N37012 ~]#

4、启动、停止、重启命令

　　systemctl start nginx.service

　　systemctl stop nginx.service

　　systemctl reload nginx.service

　　systemctl status nginx.service

5、查看nginx的状态

 [root@N37012 ~]# systemctl status nginx.service
 ● nginx.service - nginx
    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
    Active: active (running) since 日 -- :: CST; 30min ago
  Main PID:  (nginx)
     Tasks:
    CGroup: /system.slice/nginx.service
            ├─ nginx: master process /usr/local/nginx/sbin/nginx
            └─ nginx: worker process

 5月  :: N37012 systemd[]: Starting nginx...
 5月  :: N37012 systemd[]: Started nginx.
 [root@N37012 ~]#

6、杀掉进程命令

　　a.相关nginx进程全部杀掉：killall -9 nginx

　　b.把PID两个经常杀掉：kill -9 pid1 and kill -9 pid 2

6、查看版本

　　输入命令：nginx -V
