启动MySQL报Fatal error: Can’t open and lock privilege tables: Table ‘mysql.host’ doesn’t exist
今天在服务器上另开一个MySQL，新建一个配置文件修改了端口，存放目录后，服务起不来，查看错误日志发现错误行
Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist
检查数据目录，发现mysql目录没有被创建，手动执行脚本
mysql_install_db --usrer=mysql --datadir=/var/lib/mysql/newdata
再手工设置一下目录权限
chown mysql.mysql /var/lib/mysql/newdata -R
重新开启MySQL服务，运行正常
