安裝的mysql lib庫和mariadb的庫包衝突了，檢查下mariadb的組件
[root@localhost mysql5.6.34]# rpm -qa |grep mariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
果然有，趕緊幹了
[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
我靠還有依賴，強制刪除後安裝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
