升级了下MySQL数据库，同时重新启动了server，重新启动后server后，mysql报错如下：
|
0 1 |
[root@nginx var]# service mysql start Starting MySQL. ERROR! Manager of pid-file quit without updating file. |
查看mysql.log看到如下信息：
[root@nginx var]# vi /var/log/mysqld.log
|
0 1 |
140306 15:54:31 InnoDB: Started; log sequence number 0 44233 140306 15:54:31 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist |
好吧，问题找到了，来修改成之前的数据库位置。文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/error/mysql-updating-error/
[root@nginx var]# vi /etc/my.cnf
|
0 1 2 3 4 5 6 7 8 9 |
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid |
到此我以为完成了，因为服务器提示mysql数据库启动成功了，但是依然无法连接到数据库。猜测可能是权限的问题。

[mysqld] datadir=/usr/local/mysql/var socket=/tmp/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid |
做此修改后，数据库可以正常连接，一切正常！
