[求助] 无法连接mysql，请检查mysql是否已启动及用户密码是否设置正确!:

vnlife3

各位大牛好

系统：WDLINUX OS 1.0 32bit
问题发生原因：

我点击了MYSQL管理中的MYSQL设置。将默认值更改为分类的“一般”
然后点击确定。


然后点击了重启mysql就提示“无法连接mysql，请检查mysql是否已启动及用户密码是否设置正确!:”

我百度了一下运行了tools下的sh脚本，并没有作用。
重启mysqld服务提示：Starting MySQL. ERROR! Manager of pid-file quit without updating file.

还望各位指教 谢谢。 我很喜欢wdlinux也很需要它。

把/www/wdlinux/etc/my.cnf文件里的设置还原一下，然后在SSH里执行service mysqld restart即可

以下是my.cnf文件的默认设置

乌班图 安装一键 访问 8080 之后出现   无法连接mysql，请检查mysql是否已启动及用户密码是否设置正确!:
按照帖子 还原 重启，还是显示 无法连接mysql，请检查mysql是否已启动及用户密码是否设置正确!:

后台都进不去怎么弄！！！！！！

用工具sh /www/wdlinux/tools/mysql_wdcp_chg.sh

omaman

这个问题我也遇到了，看了所有的帮助都没有解决问题。后来我发现是root密码当初修改的时候我使用了"."，重启mysql正常，但是就是出现请检查密码的错误。只要修改root密码为数字字母就行了。

怎么解决，第一次接触linux，我也出现了这样的问题。。。

用工具sh /www/wdlinux/tools/mysql_wdcp_chg.sh

nano

centos 6.5 最小化安装
用 sh /www/wdlinux/tools/mysql_wdcp_chg.sh 后出现
Running..., Please Wait...
err
求解

nano

#sh /www/wdlinux/tools/mysql_root_chg.sh

Running..., Please Wait...
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

是不是数据库密码问题？执行这个shell还是不行。

nano

# /etc/rc.d/init.d/mysqld status
ERROR! MySQL is not running, but lock exists

nano

重装系统试试看行不行，可能是我以前安装过mariadb没卸载干净的原因。
