kylin v10 SP2 mysql8 编译安装

本文主要是介绍kylin v10 SP2 mysql8 编译安装，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1,环境介绍

2,去mysql官网下载包 https://dev.mysql.com/downloads/mysql/

或者  wget  https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.29-linux-glibc2.12-x86_64.tar.xz

3, 解压压缩包 改名

tar xf mysql-8.0.29-linux-glibc2.12-x86_64.tar.xz

mv mysql-8.0.29-linux-glibc2.12-x86_64 mysql

4,创建 my.cnf  启动过程中看日志my.cnf的配置和5.7是有区别的修改修改大小参数

mkdir mysql/ect

cd mysql/ect

! 建议把socket 放在 /tmp 下，否者每次连接都要指定socket

vim my.cnf

[client]
#user=xxx
#password=xxxx
port = 3306
socket = /tmp/mysql.sock

[mysqld]

5,初始化数据库  并启动

mkdir /home/mysql/dbdata -p

/home/mysql/bin/mysqld  --initialize-insecure  --basedir=/home/mysql --datadir=/home/mysql/dbdata/data

/home/mysql/bin/mysqld_safe   --defaults-file=/home/mysql/etc/my.cnf --user=root &

6,连接数据库 修改root密码

/home/mysql/bin/mysql   --socket=/tmp/mysql.sock

 ALTER USER 'root'@'localhost' IDENTIFIED BY 'Mysql!333';

7,添加环境变量

PATH="$HOME/.local/bin:$HOME/bin:/home/mysql/bin:$PATH"
