启动报错:
/opt/szy/bin/mysqld: Table \'mysql.plugin\' doesn\'t exist
141211 15:06:12 [ERROR] Can\'t open the mysql.plugin table. Please run mysql_upgrade to create it.
141211 15:06:14 [ERROR] Fatal error: Can\'t open and lock privilege tables: Table \'mysql.host\' doesn\'t exist
141211 15:06:14 mysqld_safe mysqld from pid file /opt/szy/data/mysqldevdb03.pid ended
问题分析:
百度了下,发现这是执行scripts/mysql_install_db --user=mysql没有成功的原因,没有一个初始化数据库,不能启动mysql守护进程
解决办法:
执行如下语句,szy为实例名
./scripts/mysql_install_db --user=szy --basedir=/opt/szy/ --datadir=/opt/szy/data/
重启启动,OK!
