    1.配置

    系统:centos7.6

    mysql版本:mysql 5.7

    2.这里原先的方案为:直接卸载mysql

    3.遇到的问题:

    安装mysql的最后一步时

    #yum install mysql-community-server

    遇到以下错误:

    Error: Package: 2:postfix-2.10.1-7.el7.x86_64 (@anaconda)

              Requires: libmysqlclient.so.18(libmysqlclient_18)(64bit)

              Removing: 1:mariadb-libs-5.5.60-1.el7_5.x86_64 (@anaconda)

                  libmysqlclient.so.18(libmysqlclient_18)(64bit)

              Obsoleted By: mysql-community-libs-5.7.29-1.el6.x86_64 (mysql57-community-dmr)

                  Not found

              Updated By: 1:mariadb-libs-5.5.64-1.el7.x86_64 (base)

                  libmysqlclient.so.18(libmysqlclient_18)(64bit)

    Error: Package: 2:postfix-2.10.1-7.el7.x86_64 (@anaconda)

              Requires: libmysqlclient.so.18()(64bit)

              Removing: 1:mariadb-libs-5.5.60-1.el7_5.x86_64 (@anaconda)

                  libmysqlclient.so.18()(64bit)

              Obsoleted By: mysql-community-libs-5.7.29-1.el6.x86_64 (mysql57-community-dmr)

                  ~libmysqlclient.so.20()(64bit)

              Updated By: 1:mariadb-libs-5.5.64-1.el7.x86_64 (base)

                  libmysqlclient.so.18()(64bit)

    Error: Package: mysql-community-server-5.7.29-1.el6.x86_64 (mysql57-community-dmr)

              Requires: libsasl2.so.2()(64bit)

    You could try using --skip-broken to work around the problem

    You could try running: rpm -Va --nofiles --nodigest

    查询各种信息;基本确定是因为 mysql 的依赖问题。刚开始,最快的解决方案就是卸载重装.

    4.解决方法:

    卸载,重装了两遍还是出现同样的错误。

    提示:

    Error: Package: mysql-community-server-5.7.29-1.el6.x86_64 (mysql57-community-dmr)

              Requires: libsasl2.so.2()(64bit)

    You could try using --skip-broken to work around the problem

    You could try running: rpm -Va --nofiles --nodigest


    最后解决方案:

    修改vim /etc/yum.repos.d/mysql-community.repo 源文件

    这里注意,禁用mysql其他版本,只启用5.7

    更改2点,保存后重新安装

    enabled=0

    gpgcheck=0

    yum install mysql-community-server

    以上操作完成后,完美解决

    下面来说说如何卸载

    4.1.快速删除


    yum  remove  mysql mysql-server mysql-libs mysql-server

    4.2.查找残留文件

    rpm -qa | grep -i mysql

    4.3将查询出来的文件逐个删除,如:

    yum remove mysql-community-common-5.7.29-1.el6.x86_64

    4.4.查找残留目录

    whereis mysql

    4.5逐条删除目录,如:

    rm –rf /usr/lib64/mysql

    ####这些操作完成后更新源

    5.给CentOS添加rpm源,并且选择较新的源

    wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm   --no-check-certificate

    yum localinstall mysql-community-release-el6-5.noarch.rpm

    yum repolist all | grep mysql

    yum-config-manager --disable mysql55-community

    yum-config-manager --disable mysql56-community

    yum-config-manager --enable mysql57-community-dmr

    yum repolist enabled | grep mysql

    6.查询mysql所用的版本:

    yum repolist all | grep mysql

    7.检测系统是否存在mysql

    yum list installed|grep mysql

    8.删除mysql依赖项

    yum-yremovemysql-libs.x86_64

    9.备注:需要掌握的yum命令

    9.1安装yum 仓库列表:

    yum -y   localinstall mysql57-community-release-el6-8.noarch.rpm 

    9.2查看:

    yum list | grep mysql

    9.3安装mysql

    yum -y install mysql-community-server

    10.如何禁用或启用mysql的其他版本:

    方法1:

    官网文档上给出的执行命令

    yum-config-manager --disable mysql56-community

    yum-config-manager --enable mysql57-community

    方法2:修改配置文件

    vi /etc/yum.repos.d/mysql-community.repo 

    修改完成后再次查看:yum repolist all | grep mysql
