Plugin 'FEDERATED' is disabled. /usr/sbin/mysqld: Table 'mysql.plugin' doesn't exist

问题：在linux上安装mysql的时候出现Plugin ‘FEDERATED’ is disabled.
/usr/sbin/mysqld: Table ‘mysql.plugin’ doesn’t exist问题。

[root@hadoop11 mysql]# more hadoop11.err

原因：
table ‘mysql.host’不存在的原因是因为新安装的mysql服务后，一般需要执行数据库初始化操作 ，从而生成与权限相关的表，执行命令如下：

/usr/bin/mysql_install_db --user=mysql

注：以上命令中的mysql_install_db与你安装的mysql服务位置有关，如果不知道在哪，可以使用find / -name mysql_install_db找到其位置，然后执行上面的命令。

[root@hadoop11 mysql]# find / -name mysql_install_db
/usr/bin/mysql_install_db
