本机环境：centos7使用yum安装的Nginx
1.首先输入命令 ps -ef | grep nginx检查一下nginx服务是否在运行。
[root@localhost /]# ps -ef |grep nginx
root 3163 2643 0 14:08 tty1 00:00:00 man nginx
root 5427 1 0 14:50 ? 00:00:00 nginx: master process nginx
nginx 5428 5427 0 14:50 ? 00:00:00 nginx: worker process
root 5532 2746 0 14:52 pts/0 00:00:00 grep --color=auto nginx
2.停止Nginx服务
[root@localhost /]# /usr/sbin/nginx -s stop
[root@localhost /]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1261/sshd
tcp6 0 0 :::111 :::* LISTEN 1/systemd
tcp6 0 0 :::22 :::* LISTEN 1261/sshd
3.查找、删除Nginx相关文件
- 查看Nginx相关文件：whereis nginx
[root@localhost /]# whereis nginx
nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man8/nginx.8.gz /usr/share/man/man3/nginx.3pm.gz
- find查找相关文件
[root@localhost /]# find / -name nginx
/usr/lib64/perl5/vendor_perl/auto/nginx
/usr/lib64/nginx
/usr/share/nginx
/usr/sbin/nginx
/etc/logrotate.d/nginx
/etc/nginx
/var/lib/nginx
/var/log/nginx
- 依次删除find查找到的所有目录：rm -rf /usr/sbin/nginx
4.再使用yum清理
[root@localhost /]# yum remove nginx
