二进制/源码编译安装mysql 8.0
二进制方式：
1.下载或上传安装包至设备：
2.创建组与用户：
[root@openEuler-1 ~]# groupadd mysql
[root@openEuler-1 ~]# useradd -r -g mysql -s /bin/false mysql
3.解压安装包：
tar xf mysql-8.0.36-linux-glibc2.12-x86_64.tar.xz -C /usr/local
4.建立软链接：
ln -sv /usr/local/mysql-8.0.36-linux-glibc2.12-x86_64/ /usr/local/mysql
5.初始化：
[root@openEuler-1 ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data
2025-01-15T15:01:42.254967Z 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.36) initializing of server in progress as process 1935
2025-01-15T15:01:42.260421Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2025-01-15T15:01:42.971402Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2025-01-15T15:01:44.318709Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: >HYAHNuRd4+f （初始密码）
6.编辑配置文件：
[root@openEuler-1 ~]# vim /etc/my.cnf
basedir=/usr/local/mysql/
datadir=/usr/local/mysql/data/
socket=/tmp/mysql.sock
log-error=/usr/local/mysql/data/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid
7.给予软件目录权限：
[root@openEuler-1 ~]# chown -R mysql.mysql /usr/local/mysql/*
8.拷贝服务脚本：
[root@openEuler-1 ~]# cd /usr/local/mysql/
[root@openEuler-1 mysql]# ls
bin data docs include lib LICENSE man README share support-files
[root@openEuler-1 mysql]# cd support-files/
[root@openEuler-1 support-files]# ls
mysqld_multi.server mysql-log-rotate mysql.server
[root@openEuler-1 support-files]# cp mysql.server /etc/init.d/mysqld
9.将服务脚本添加为系统服务：
[root@openEuler-1 support-files]# chkconfig --add mysqld
[root@openEuler-1 support-files]# ll /etc/rc.d/rc3.d/
total 0
lrwxrwxrwx 1 root root 16 Jan 15 23:30 S64mysqld -> ../init.d/mysqld
10.将服务脚本设置为开机自启动：
[root@openEuler-1 support-files]# chkconfig mysqld on
[root@openEuler-1 support-files]# chkconfig --list mysqldNote: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
11.启动服务：
[root@openEuler-1 ~]# systemctl start mysql
[root@openEuler-1 ~]# systemctl status mysql

12.安装依赖：
[root@openEuler-1 ~]# yum install ncurses-compat-libs
13.使用绝对路径登录，并修改密码：
[root@openEuler-1 ~]# /usr/local/mysql/bin/mysql -uroot -p
Enter password: （>HYAHNuRd4+f）

[root@openEuler-1 ~]# vim /etc/profile.d/mysql.sh
#!/bin/bash
export PATH=$PATH:/usr/local/mysql/bin/
[root@openEuler-1 ~]# source /etc/profile.d/mysql.sh #使立即生效，加载到 当前
验证：
[root@openEuler-1 ~]# mysql -uroot -p123
