  今天连接mysql数据库的时候遇到一个问题:Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

  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:

  [mysql d]

  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

  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!

  但我的系统中没有找到mysql.sock文件,只有mysqld.sock文件,/var/run/mysqld/mysqld.sock

  于是仿照上面的做法: ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

  这样,可以正常连接数据库了.。
