起因:我在Ubuntu14 64位系统中安装mysql后,后来通过mysql -u用户名 -p密码 的命令连接 Mysql数据库时,报错"can't connect to local mysql serverthrough socket'/var/run/mysqld/mysqld.sock'" 解决方法1: 在不重新安装mysql的情况下,通过如下命令来解决,具体的就是先停止mysql服务,再重新开启mysql服务 cd /etc/init.d sudo service mysql
问题发生背景 问题实例之前使用的是percona server,是安装pmm镜像自带的数据库,之后通过mysqldump迁移到了MySQL server,目前是只有有pmm server 访问pmm库,MySQL server就crash,并通过守护进程mysqld_safe 自动重启,crash 集尝试重启的一部分信息如下 :: UTC - mysqld got signal ; This could be because you hit a bug. It is also possible
执行mysqld_safe报错: [root@edu data]# /usr/local/mysql5.7/bin/mysqld_safe --user=mysql160427 12:41:28 mysqld_safe Logging to '/renqinglei/mysql/log/mysql_error.log'.160427 12:41:28 mysqld_safe The file /usr/local/mysql/bin/mysqlddoes not exist or is not

在一台ubuntu测试机器上启动一个mysql实例,本来应该是一件很简单的事情, 启动的时候却报错了: mysqld_safe --defaults-file=/etc/mysql/my3307.cnf 160218 15:45:13 mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take

1.问题原因与解决办法 因为修改了MySQL临时文件的目录后,使用service mysqld restart重启MySQL出现如下错误: service: no such service mysqld 错误原因: 是因为我们在编译安装MySQL时没有将MySQL的控制脚本mysql.server拷贝到/etc/init.d/中. 解决办法: 将MySQL的安装目录下的support-files/mysql.server拷贝到/etc/init.d/中,并重命名为mysqld.拷贝命令如下: #
1.启动命令 systemctl start mysqld.service 或者 /etc/init.d/mysqld start 结果同样的错误 2.错误是: Job for mysqld.service failed. See 'systemctl status mysqld.service' and 'journalctl -xn' for details. 3.按照提示输入命令 systemctl status mysqld.service 或者 journalctl -xn 命令后
