centos7.6安装nginx

基本的nginx的安装和简单配置，并不包括其他

1. 查看是否被安装

[root@iZhp3 etc]# which nginx
/usr/sbin/nginx #值为空表示没有被安装

1. 安装nginx

[root@iZhp3 etc]# yum install -y nginx

1. 查看nginx安装后文件分布的目录

[root@iZhp3 etc]# whereis nginx
nginx:
/usr/sbin/nginx  #执行目录
/usr/lib64/nginx  #模块目录
/etc/nginx  #配置目录
/usr/share/nginx  #站点
/usr/share/man/man8/nginx.8.gz
/usr/share/man/man3/nginx.3pm.gz

1. 注册为开启自启动服务以及开启关闭等，参见vsftpd安装一节
2. 查看端口占用及软件运行情况

[root@iZhp3bl var]# netstat -antp|grep :80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      13294/nginx: master

tcp6       0      0 :::80                   :::*                    LISTEN      13294/nginx: master
[root@iZhp3b var]# ps aux|grep nginx
root     13294  0.0  0.1 120900  2100 ?        Ss   15:30   0:00 nginx: master process /usr/sbin/nginx
nginx    13296  0.0  0.1 121284  3568 ?        S    15:30   0:00 nginx: worker process
root     13351  0.0  0.0 112708   988 pts/0    R+   15:33   0:00 grep --color=auto nginx

1. 进程关闭

[root@i var]# killall -9 nginx
[root@iZh var]# kill -9 pid1 and kill -9 pid1  #pid进程

1. 查看版本

[root@iZhp var]# nginx -v
nginx version: nginx/1.16.1

1. 基本配置 nginx.conf文件

[root@iZhp nginx]# cat nginx.conf
