找不到 mysql_upgrade

Question

我刚刚升级了我的系统，但是Mysql没有启动:

120319 15:20:39 [Note] Plugin 'FEDERATED' is disabled.
mysqld: Table 'mysql.plugin' doesn't exist
120319 15:20:39 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
120319 15:20:39  InnoDB: Initializing buffer pool, size = 8.0M
120319 15:20:39  InnoDB: Completed initialization of buffer pool
120319 15:20:39  InnoDB: Started; log sequence number 0 43665
120319 15:20:39 [ERROR] Can't start server : Bind on unix socket: No such file or directory
120319 15:20:39 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?
120319 15:20:39 [ERROR] Aborting

所以我被要求运行 myslq_upgrade，但它不存在于系统中...

有什么帮助吗？

我发现它在 Amazon Linux 1 AMI 上已安装但不在 PATH 中。我执行了 sudo find/-type f -name mysql_upgrade，它位于 /usr/libexec/mysql55/mysql_upgrade 中。
