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

1 [root@N37012 ~]# systemctl status nginx.service 2 ● nginx.service - nginx 3    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled) 4    Active: failed (Result: exit-code) since 日 2019-05-19 16:31:16 CST; 15min ago 5   Process: 23482 ExecStop=/usr/local/nginx/sbin/nginx quit (code=exited, status=1/FAILURE) 6  Main PID: 7158 (code=exited, status=0/SUCCESS) 7  8 5月 19 16:00:29 N37012 systemd[1]: Starting nginx... 9 5月 19 16:00:30 N37012 systemd[1]: Started nginx.10 5月 19 16:31:15 N37012 systemd[1]: Stopping nginx...11 5月 19 16:31:15 N37012 nginx[23482]: nginx: invalid option: "quit"12 5月 19 16:31:16 N37012 systemd[1]: nginx.service: control process exited, code=exited status=113 5月 19 16:31:16 N37012 systemd[1]: Stopped nginx.14 5月 19 16:31:16 N37012 systemd[1]: Unit nginx.service entered failed state.15 5月 19 16:31:16 N37012 systemd[1]: nginx.service failed.16 [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

1 [root@N37012 ~]# systemctl status nginx.service  2 ● nginx.service - nginx 3    Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled) 4    Active: active (running) since 日 2019-05-19 16:00:30 CST; 30min ago 5  Main PID: 7158 (nginx) 6     Tasks: 2 7    CGroup: /system.slice/nginx.service 8            ├─7158 nginx: master process /usr/local/nginx/sbin/nginx 9            └─7159 nginx: worker process10 11 5月 19 16:00:29 N37012 systemd[1]: Starting nginx...12 5月 19 16:00:30 N37012 systemd[1]: Started nginx.13 [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
