mysql Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.s

mysql Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’
今天在linux中安装了mysql但在连接时出现Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’提示,下面我总结了一些解决办法和用百度搜索的一些参数文档。  linux 环境下。所有数据库以及用户信息的存放位置可以在(vim /etc/my.cnf)查看.
  读取不到数据库信息(原因:移动datadir过程中权限也改变了[chown mysql:mysql -R datadir]) ,datadir是你的存放路径。
代码如下复制代码ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’  (2),解决方法[查看是不是存在该文件。修改相应的路径 vim /etc/my.cnf,查看是不是权限不对.ls -l ].
代码如下复制代码ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’  (111),解决方法[修改相应的路径 vim /etc/my.cnf]
  添加下面这段:
代码如下复制代码  port            = 3306
  socket          = /var/lib/mysql_data/mysql.sock
  mysql 数据表使用中,错误提示:”martin” is marked as crashed and should be repaired
  解决方法:
  进入mysql的data目录,在命令行执行:myisamchk -c -r martin.MYI
  mysql允许远程连接方法:在添加mysql用户的时候host选现修改成”%”就可以了。
  以后遇到的mysql问题会一并添加上来.
  网络上其它 方法
  问题终于解决:
  方法:    修改/etc/my.conf:
代码如下复制代码
  datadir=/usr/local/mysql/data
  socket=/var/lib/mysql/mysql.sock

  user=mysql
  basedir=/usr/local/mysql
  If there is not currently a section called , add one at the bottom of the file and copy the socket= line under the section such as:

  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
代码如下复制代码/usr/local/mysql/bin/mysqld_safe  问题解决了
  官网的一点解决办法

  if you are new to installing mysql server you might probably> 代码如下复制代码  > mysql
  ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'
  To fix:
  First start the mysql daemon, then type mysql
代码如下复制代码  > /etc/init.d/mysqld start
  > mysql
  Bingo! It worked for me!
  To update mysql root password
代码如下复制代码  mysql> USE mysql;
  mysql> UPDATE user SET Password=PASSWORD('new-password') WHERE user='root';
  mysql> FLUSH PRIVILEGES;
  To add a new user to mysql
  1. First login as root then create a database ‘demo’
  > mysql -u root -p
代码如下复制代码Enter password:  mysql> create database demo;
  After that create a new user named ‘guest’ with password ‘guest’ with all previleges assigned to demo database;
代码如下复制代码
  mysql> GRANT ALL PRIVILEGES ON mytest.* TO 'guest'@'localhost'>  Then exit mysql and connect through username guest;
  That should work!
  Note:This could happen, if you run out of your disk space.Check your disk space.
