錯誤原因：
安裝的mysqllib庫和mariadb的庫包衝突了，檢查下mariadb的組件
[root@localhost mysql5.6.34]# rpm -qa |grepmariadb
mariadb-libs-5.5.44-2.el7.centos.x86_64
刪除衝突組件
[root@localhost mysql5.6.34]# rpm -emariadb-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
有依賴，強制刪除
[root@localhost mysql5.6.34]# rpm -emariadb-libs-5.5.44-2.el7.centos.x86_64 --nodeps
重新安裝mysql
[root@localhost mysql5.6.34]# rpm -ivhMySQL-server-5.6.34-1.el7.x86_64.rpm
