lnmp环境下MYSQL启动失败，提示Can’t find file ‘.mysqlhost.frm’解决办法

MYSQL启动失败，提示Can’t find file: ‘./mysql/host.frm’解决办法

虚拟机默认启动Mysql,发现没有启动得了，于是，看了下Mysql的启动日志，如下：

110315 10:17:51  InnoDB: Started; log sequence number 0 43655
110315 10:17:51 [ERROR] /usr/libexec/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
110315 10:17:51 [ERROR] /usr/libexec/mysqld: Can't find file: './mysql/host.frm' (errno: 13)
110315 10:17:51 [ERROR] Fatal error: Can't open and lock privilege tables: Can't find file: './mysql/host.frm' (errno: 13)
110315 10:17:51  mysqld ended

解决办法：

1： 初始化数据库做了没有？

/usr/local/mysql/bin/mysqld_install_db –user=mysql

2：权限问题

chown -R root.mysql /usr/local/mysql/
chown -R mysql /usr/local.mysql/var/

调整lib库路径：

echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf

重新加载配置

ldconfig

启动mysql

/usr/local/mysql/bin/mysql_safe --user=mysql &

查看是否启动了

netstat -ntpl | grep 3306
