mysql unsupported data type如何处理

最近在安装jumpserver

因为想实现环境隔离,想在一台服务器上安装多个服务器应用,于是采用docker安装

指定了mysql和redis

然后启动docker

查看日志提示不支持jsonfield

于是安装mysql5.7

添加Mysql5.7仓库

`sudo rpm -ivh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm`

确认Mysql仓库成功添加

`sudo yum repolist all | grep mysql | grep enabled`

如果展示像下面,则表示成功添加仓库:

>mysql-connectors-community/x86_64 MySQL Connectors Community enabled: 51
mysql-tools-community/x86_64 MySQL Tools Community enabled: 63
mysql57-community/x86_64 MySQL 5.7 Community Server enabled: 267

开始安装Mysql5.7

`sudo yum -y install mysql-community-server`

启动Mysql

`sudo systemctl start mysqld`

设置系统启动时自动启动

`sudo systemctl enable mysqld`

查看启动状态

`sudo systemctl status mysqld`

Mysql的安全设置

CentOS上的root默认密码可以在文件/var/log/mysqld.log找到,通过下面命令可以打印出来

`cat /var/log/mysqld.log | grep -i 'temporary password'`

执行下面命令进行安全设置,这个命令会进行设置root密码设置,移除匿名用户,禁止root用户远程连接等

mysql_secure_installation

设置数据库编码为utf8

打开配置文件

sudo vim /etc/my.cnf

在[mysqld],[client],[mysql]节点下添加编码设置

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8

重启Mysql即可

sudo systemctl restart mysqld
