mysql启动报file don't exists

安装mysql为mysql-5.6.36-linux-glibc2.5-x86_64
service mysql start
错误信息：
Starting MySQL.170623 10:57:50 mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).

卸载插件mariadb后，重新安装还是报上面的错误信息
