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 依赖关系解决 ====================================================================================================== Package 架构 版本 源 大小 ====================================================================================================== 正在删除: nginx x86_64 1:1.12.2-3.el7 @epel 1.5 M 为依赖而移除: nginx-all-modules noarch 1:1.12.2-3.el7 @epel 0.0 nginx-mod-http-geoip x86_64 1:1.12.2-3.el7 @epel 21 k nginx-mod-http-image-filter x86_64 1:1.12.2-3.el7 @epel 24 k nginx-mod-http-perl x86_64 1:1.12.2-3.el7 @epel 54 k nginx-mod-http-xslt-filter x86_64 1:1.12.2-3.el7 @epel 24 k nginx-mod-mail x86_64 1:1.12.2-3.el7 @epel 99 k nginx-mod-stream x86_64 1:1.12.2-3.el7 @epel 157 k 事务概要 ====================================================================================================== 移除 1 软件包 (+7 依赖软件包) 安装大小：1.9 M 是否继续？[y/N]： ok nginx 卸载完成！
