昨天我更新了我的 manjaro。从那以后我遇到了很多问题。

首先，我输入

systemctl status mysqld.service

启动 MySQL，但它出错了

mysqld.service: Start request repeated too quickly.

我找到了很多建议，但它们不起作用。

我已经尝试过：

  • 使用以下命令检查 MySQL 数据目录的权限。所有权应该是mysql:mysql，目录权限应该是 700。

    ls -ld /var/lib/mysql/

  • 使用以下命令检查 MySQL 数据目录中数据库的权限。所有权应该是mysql:mysql该目录中的所有文件。

    ls -lh /var/lib/mysql/

  • 使用命令检查监听网络 TCP 端口

    netstat -ntlp

  • 使用以下命令检查 MySQL 日志文件是否有任何错误：

    cat /var/log/mysql/mysqld.log

  • 尝试使用启动 MySQL

    mysqld_safe --defaults-file=/etc/my.cf

我的错误：

遇到类似的问题。按照步骤（Sql server 版本：'8.0.22-0ubuntu0.20.04.3'）

 1. Edit file: mysqld.cnf under directory: /etc/mysql/mysql.conf.d
 2. Ensure that below basic settings are made in file mysqld.cnf and save it.
 # * Basic Settings
 user       = mysql
 pid-file   = /var/run/mysqld/mysqld.pid
 socket     =   /var/run/mysqld/mysqld.sock
 port       = 3306
 datadir    = /var/lib/mysql
 # setting for localhost
 bind-address       = 127.0.0.1
 mysqlx-bind-address    = 127.0.0.1
 log_error = /var/log/mysql/error.log
 server-id      = 1
 log_bin            = /var/log/mysql/mysql-bin.log
 max_binlog_size    = 100M
 3. Check error log files under directory: /var/log/mysql 
 4. Remove all log files: Cd /var/log/mysql $ sudo rm -R error*
 5. Start mysql server: $ sudo systemctl start mysql.service
 6. Check status of mysql server: $ sudo systemctl status mysql.service

对我们来说，它是chown日志文件：

[root@tree ~]# ls -alh /var/log/mysqld.log 
-rw-r----- 1 root logs 8.3K Apr 20 02:17 /var/log/mysqld.log
[root@tree ~]# chown mysql: /var/log/mysqld.log 
[root@tree ~]# systemctl start mysqld
[root@tree ~]# systemctl status mysqld

摆脱了同样的失败。

我遇到了同样的问题并像这样解决了这个问题：

如果/var/log/mysql文件夹不存在：

sudo mkdir /var/log/mysql

然后授予此文件夹的权限：

sudo chown -R mysql:mysql /var/log/mysql

sudo systemctl stop mysql

sudo systemctl start mysql

这对我有用。

sudo rm -rf /var/lib/mysql/*
