mysql 突然访问不了,登上服务器发现,mysql进程不见了。
错误:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
发现是权限问题导致的。
改变权限 #chown -R mysql:mysql /var/lib/mysql
[root@localhost ~]# /etc/init.d/mysqld start
具体什么原因导致的。还在查询。。。
引用别人博客内容:
启动mysql 报错:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
1、先查看 /etc/rc.d/init.d/mysqld status 看看m y s q l 是否已经启动.
另外看看是不是权限问题.
2、确定你的mysql.sock是不是在那个位置,
mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock
3、试试:service mysqld start
4、如果是权限问题,则先改变权限 #chown -R mysql:mysql /var/lib/mysql
[root@localhost ~]# /etc/init.d/mysqld start
启动 MySQL: [ 确定 ]
[root@localhost ~]# mysql -uroot -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
原因是,/var/lib/mysql 的访问权限问题。
shell> chown -R mysql:mysql /var/lib/mysql
接着启动服务器
shell> /etc/init.d/mysql start
服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。
但是我的问题仍然没有得到解决。
问题终于解决:
方法: 修改/etc/my.conf:
[mysqld]
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
[mysql.server]
user=mysql
basedir=/usr/local/mysql
If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:
[client]
socket=/var/lib/mysql/mysql.sock
发现依旧如此,运行
/etc/init.d/mysql start报错: Starting MySQLCouldn't find MySQL manager or server
是mysqld服务没启,运行/usr/local/mysql/bin/mysqld_safe &
问题解决。
亲测有效,解决Can ‘t connect to local MySQL server through socket ‘/tmp/mysql.sock ‘(111) “;
我出现的问题是:找不到mysql.sock
