centos7通过yum装完mysql,使用grep 'temporary password' /var/log/mysqld.log找不到root密码打开mysqld.log中根本没有temporary password 1.删除原来安装过的mysql残留的数据(这一步非常重要,问题就出在这)rm -rf /var/lib/mysql 2.重启mysqld服务systemctl restart mysqld 3.再去找临时密码grep 'temporary password' /var/log

环境是CentOS6.5,先贴个错误代码: 这个问题解决了大半天,浪费了好多时间,不过也算是值了. 事故起因是因为突然断电,mysql server直接干掉了,也没有备用电源,重启了之后看日志tail -f /var/log/mysqld.log,刚开始报错: 错误信息 :ERROR 2002 (HY000): Can't connect to local MySQL server server through socket '/var/lib/mysql/mysql.sock'(111) 报错

鉴于很多童鞋反应,mysql5.7安装后出现无法启动,建立/var/run/mysqld 并赋权mysql用户解决了启动的问题,但是重启系统后又出现无法启动的问题,导致/var/run/mysqld 目录每次重启后都需要手动去创建并赋权mysql用户才能起到mysql,可以说,这是mysql5.7的一个小BUG,经过探索实践,现给出终极解决方案: 首先申明,修改my.cnf没有用. 之所以/var/run/mysqld 目录每次重启后都需要手动去创建,是因为/var/run/目录下建立文件夹是在

msql启动报错,启动不了. 进入mysql日志默认的路径为 /var/log/mysqld.log 查看日志,发现报错信息如下: can't create/write to file 'var/run/mysqld/mysqld.pid 解决办法: 将 /var/run/mysqld/权限赋给mysql 执行以下命令即可: chown -R mysql /var/run/mysqldchgrp -R mysql /var/run/mysqld--------------------- 作者:冬

SQL Server数据库备份有两种方式,一种是使用BACKUP DATABASE将数据库文件备份出去,另外一种就是直接拷贝数据库文件mdf和日志文件ldf的方式.下面将主要讨论一下后者的备份与恢复.本文假定您能熟练使用SQL Server Enterprise Manager(SQL Server企业管理器)和SQL Server Quwey Analyser(SQL Server查询分析器)1.正常的备份.恢复方式 正常方式下,我们要备份一个数据库,首先要先将该数据库从运行的数据服务器中断开

我们的LAMP是搭建在UBUNTU 12.04 LTS上的. LAMP是通过编译的方式进来安装的. 在一次处理意外挂机时由于未知的原因在重启后发现无法连接数据库了, 在打开网站时出现如下的的提示: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) 出错的信息已经提示的很清楚, 就是/var/run/mysqld/mysqld.sock 这

问题:在从 https://c.163.com/hub#/m/repository/?repoId=3093 下载镜像 docker pull hub.c.163.com/library/jenkins:latest后,启动容器时,报错: [admin@3-29 ~]$ sudo docker run --name myjenkins-slave1 -p 8080:8080 -v /var/lib/jenkins:/var/jenkins_home hub.c.163.com/library/j

docker 运行后, 执行docker logs -f myjenkins时报错: touch: cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions? 需要修改下目录权限, 因为当映射本地数据卷时,/home/docker/je

安装上mysql后,报 Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock',试了网上的方法都没有用,于是打开/etc/my.cnf查看. 看到这么一段:   # The MySQL server  26 [mysqld]  27 port            = 3306  28 socket          = /tmp/mysql.sock  29 skip-external-l

在使用 deamon@deamon-H55M-S2:/usr/bin$ mysqladmin -u root -p shutdown 关闭MySQL之后试图通过: deamon@deamon-H55M-S2:/usr/bin$ mysqld_safe & 来重启服务器,发现重启失败,显示权限不够: /usr/bin/mysqld_safe: 548: /usr/bin/mysqld_safe: cannot create /var/lib/mysql/mysqld_safe.pid: Permi

This is about resetting the MySQL 5.7 root password in Ubuntu 16.04 LTS You probably tried something like this: sudo service mysql stop mysqld_safe --skip-grant-tables & And then got something like this (stangely, exists is misspelled in the output):

  Android.util.Log常用的方法有以下5个:Log.v() Log.d() Log.i() Log.w() 以及 Log.e() .根据首字母对应VERBOSE,DEBUG,INFO, WARN,ERROR.   1.Log.v 的调试颜色为黑色的,任何消息都会输出,这里的v代表verbose啰嗦的意思,平时使用就是Log.v("","");   2.Log.d的输出颜色是蓝色的,仅输出debug调试的意思,但他会输出上层的信息,过滤起来可以通过DDM
