repository epel is listed more than once in the configuration

执行yum install命令时报错 Loaded plugins: fastestmirror, langpacks

Repository epel is listed more than once in the configuration

执行yum list命令时报错 Existing lock /var/run/yum.pid: another copy is running as pid 10841.

报错出现的情况具体为：

[root@xx_0_15_centos /]#
[root@xx_0_15_centos /]# yum install
Loaded plugins: fastestmirror, langpacks
Repository epel is listed more than once in the configuration
Error: Need to pass a list of pkgs to install

第一个错误 (Loaded plugins: fastestmirror, langpacks)

yum install 的时候提示：Loaded plugins: fastestmirror, langpacks（fastestmirror是yum的一个加速插件，这里是插件提示信息是插件不能用了。）

于是进行解决

1.修改插件的配置文件

vi /etc/yum/pluginconf.d/fastestmirror.conf

enabled = 1 //由1改为0，禁用该插件 1

2.修改yum的配置文件

vi /etc/yum.conf

plugins=1 //改为0，不使用插件 1

3 清除缓存并重新构建yum源

yum clean all

yum clean dbcache

yum makecache

（注：此种方法临时用可以，但不能应用于生产环境）参考资料：Loaded plugins:fastestmirror,langpacks并非错误，而是两者插件。fastest是最快的，mirror是镜像。所以fastestmirror是帮助你找到最快捷的yum仓库的插件，lang是language语言的缩写，packs是packages包裹的缩写，langpacks是语言包插件。不建议采用在/etc/yum.repos.d目录中打开.repo文件，将gpgcheck=1改成0 的方法。GPGCHECK是检查软件包是否被篡改的一个重要工具。1是启用，0是禁用。把它由1改0，等于放弃安全检查。这无异于把自己家的大门拆掉窗户打开防盗网卸掉。随便什么人什么时间都能进你家来。自己玩玩linux可以，在生产环境中，最好别这么做。（https://zhidao.baidu.com/question/2079050521830535708.html）

第二个错误 (Repository epel is listed more than once in the configuration)

但这时候执行yum clean all又报错了： Repository epel is listed more than once in the configuration
Existing lock /var/run/yum.pid: another copy is running as pid 18533. (这里其实是有两个报错，挨个进行解决)

[root@VM_0_15_centos yum.repos.d]# yum clean all
Repository epel is listed more than once in the configuration
Existing lock /var/run/yum.pid: another copy is running as pid 18533.

解决方案：

1、打包/etc/yum.repos.d/目录下的所有文件，以备恢复使用，运行命令：zip centos7-repo.zip /etc/yum.repos.d/*

2、打包完毕，再运行ls命令查看多了一个zip文件，正是我们打包的文件

[root@xx_0_15_centos yum.repos.d]# ls
centos7-repo.zip CentOS-Base.repo CentOS-Epel.repo epel.repo epel-testing.repo
[root@xx_0_15_centos yum.repos.d]#

3、删除多余文件，运行rm -rf !(centos7-repo.zip)命令，意思是删除除.zip文件以外的所有文件，再次ls查看已经都删除了

4、到阿里开源镜像站点下载系统对应版本的repo文件，运行wget http://mirrors.aliyun.com/repo/Centos-7.repo命令

下载完后再次查看已经多出来一个centos-8.repo文件，再次运行yum list installed | grep docker命令，不再有任何提示。说明没有安装过docker！

这时报错Repository epel is listed more than once in the configuration已经修复，执行yum list installed | grep docker可以测出已修复。

第三个错误 (Existing lock xxx pid xxx)

但报错Existing lock /var/run/yum.pid: another copy is running as pid 18533.依然存在

Existing lock xxx pid xxx 这个报错的原因是：之前安装时是异常停止的，被锁定。一般正常安装完的，就没有这个文件了

解决方案：

1. /var/run/yum.pid

2.将 /var/run/ 目录下的 yum.pid文件删除即可。
