mysql Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’
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[datadir=/usr/local/ mysql_data ].
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。
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 ].
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:
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:
[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

mysql Can’t connect to local MySQL server through 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
问题解决了
官网的一点解决办法
if you are new to installing mysql server you might probably face this error quite often if you type mysql in the shell prompt.
> 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
> /etc/init.d/mysqld start
> mysql
Bingo! It worked for me!
To update mysql root password
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
Enter password:
mysql> create database demo;
After that create a new user named ‘guest’ with password ‘guest’ with all previleges assigned to demo database;
mysql> GRANT ALL PRIVILEGES ON mytest.* TO 'guest'@'localhost' IDENTIFIED BY 'guest' WITH GRANT OPTION;
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.
