安装的mysql lib库和mariadb的库包冲突了，检查下mariadb的组件

[root@localhost mysql5.6.34]# rpm -qa |grep mariadb

mariadb-libs-5.5.44-2.el7.centos.x86_64

果然有，赶紧干了

[root@localhost mysql5.6.34]# rpm -e mariadb-libs-5.5.44-2.el7.centos.x86_64

error: Failed dependencies:

        libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

        libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64

我靠还有依赖，强制删除后安装mysql 5.6.34

[root@localhost mysql5.6.34]# rpm -e mariadb-libs-5.5.44-2.el7.centos.x86_64 --nodeps

[root@localhost mysql5.6.34]# rpm -ivh MySQL-server-5.6.34-1.el7.x86_64.rpm
