Linux删除Nginx有残留怎么办

前言：玩docker的时候，不小心在linux系统里面装了nginx，然后docker里面也装了nginx

使用nginx时有些混淆，然后

一、docker删除nginx步骤：

1.1、找到容器id

1.  
   [root@VM-4-7-centos ~]# docker ps -a
2.  
   CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3.  
   1d526cafca50 nginx "/docker-entrypoint.…" 54 minutes ago Up 19 minutes 0.0.0.0:89->80/tcp, :::89->80/tcp mynignx

1.2、执行删除命令

docker rm -f 1d526cafca50

二、linux删除nginx步骤

2.1、执行删除命令

[root@VM-4-7-centos ~]# yum remove nginx

三、确认nginx是否删除干净

whereis nginx

3.1发现还有残留

1.  
   [root@VM-4-7-centos ~]# whereis nginx
2.  
   nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz

3.2找到nginx

find -name nginx

这边有个小坑（执行查找语句时需要进入根目录查找）

1.  
   #home目录
2.  
   [root@VM-4-7-centos ~]#
3.  
   #根目录
4.  
   [root@VM-4-7-centos /]#

3.3查出nginx目录如下

1.  
   [root@VM-4-7-centos /]# find -name nginx
2.  
   ./etc/logrotate.d/nginx
3.  
   ./etc/nginx
4.  
   ./usr/share/nginx
5.  
   ./usr/lib64/nginx
6.  
   ./usr/sbin/nginx
7.  
   ./var/log/nginx
8.  
   ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/etc/default/nginx
9.  
   ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/etc/logrotate.d/nginx
10.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/etc/init.d/nginx
11.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/etc/nginx
12.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/usr/lib/nginx
13.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/usr/share/doc/nginx
14.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/usr/share/nginx
15.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/usr/sbin/nginx
16.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/var/log/nginx
17.  
    ./var/lib/docker/overlay2/921516d73040cfd2a2b225ebf6ac689f0a1a653688a4e891efcda4de69b88963/diff/var/cache/nginx
18.  
    ./var/lib/nginx

四、删除目录

[root@VM-4-7-centos /]# rm -rf /etc/logrotate.d/nginx

删除完成再用

find -name nginx 查一遍
