ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/usr/local/mysql/mysql.sock'
输入
#mysql -u root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/usr/local/mysql/mysql.sock' (111)
随即上网找寻答案
根据大家提供的方法我逐一尝试
方案1.
1.#ps -A|grep mysql
显示类似：
1829 ? 00:00:00 mysqld_safe
1876 ? 00:00:31 mysqld
2.#kill -9 1829
3.#kill -9 1876
4.#/etc/init.d/mysql restart
5.#mysql -u root -p
他的麻烦解决了,我的还没解决!
继续找
方案2
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.
------------------------------------------------------------------------------------
[root@localhost beinan]#chown -R mysql:mysql /var/lib/mysql
[root@localhost beinan]# /etc/init.d/mysqld start
启动 MySQL： [ 确定 ]
[root@localhost lib]# mysqladmin -uroot password '123456'
[root@localhost lib]# mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or /g.
Your MySQL connection id is 3 to server version: 4.1.11
Type 'help;' or '/h' for help. Type '/c' to clear the buffe
他的也解决了,我的麻烦还在继续,依然继续寻找
方案3
问题解决了，竟然是max_connections=1000 他说太多了，然后改成500也说多，无奈删之问题解决了。
还是不行
方案4
/var/lib/mysql 所有文件权限 改成mysql.mysql
不行不行
方案5
摘要：解决不能通过mysql .sock连接MySQL问题 这个问题主要提示是，不能通过 '/tmp/mysql .sock'连到服务器，而php标准配置正是用过'/tmp/mysql .sock'，但是一些mysql 安装方法 将 mysql .sock放在/var/lib/mysql .sock或者其他的什么地方，你可以通过修改/etc/my.cnf文件来修正它，打开文件，可以看到如下的东东：
[mysqld]
socket=/var/lib/mysql .sock
改一下就好了，但也会引起其他的问题，如mysql 程序连不上了，再加一点：
[mysql]
socket=/tmp/mysql .sock
或者还可以通过修改php.ini中的配置来使php用其他的mysql .sock来连，这个大家自己去找找
注意是mysql不是mysqld
或者用这样的方法:
ln -s /var/lib/mysql /mysql .sock /tmp/mysql .sock
成功了,就是这样ln -s /var/lib/mysql /mysql .sock /tmp/mysql .sock
OK!
