下载离线包

 

tar -xvf mysql-server_8.4.3-1ubuntu24.04_amd64.deb-bundle.tar -C /mysql

解压完依次执行：

dpkg -i  mysql-community-client-plugins_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-community-client-core_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-common_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-community-client_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-client_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  libmysqlclient24_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  libmysqlclient-dev_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-community-server-core_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-community-server_8.4.3-1ubuntu24.04_amd64.deb
dpkg -i  mysql-server_8.4.3-1ubuntu24.04_amd64.deb
如遇失败：sudo apt-get remove --purge ...

mysql server安装过程中会提示输入root用户密码，待所有安装完成后，使用命令登陆即可。如密码设置为123456

查看启动状态

sudo systemctl start mysql

设置MySQL开机启动：

sudo systemctl enable mysql

默认都是localhost，把root调整为远程登录用户
use mysql;
update user set host = '%' where user = 'root';

刷新
FLUSH PRIVILEGES;

优化Mysql配置
mysql> set global max_connections=3000 ##最大连接数
mysql> set global thread_cache_size=60; ##最大并发数
