mysql Can’t connect to local MySQL server through socket ‘
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。所有以及用户信息的存放位置可以在(vim /etc/my.cnf)查看[datadir=/usr/local/_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。
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 |
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 |
[mysqld] [mysql.server] 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] |
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 face this error quite often if you type mysql in the shell prompt.
代码如下 | 复制代码 |
> mysql |
To fix:
First start the mysql daemon, then type mysql
代码如下 | 复制代码 |
> /etc/init.d/mysqld start |
Bingo! It worked for me!
To update mysql root password
代码如下 | 复制代码 |
mysql> USE mysql; |
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' 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.
