ARM架构下面安装mysql5.7.22
下载地址为：https://obs.cn-north-4.myhuaweicloud.com/obs-mirror-ftp4/database/mysql-5.7.27-aarch64.tar.gz
1. 添加mysql用户组和mysql用户，用于隔离mysql进程
[root@arm ~]# groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql
2.安装依赖库
[root@arm ~]# yum install -y libaio*
3. 下载解压Mysql
[root@arm ~]# wget https://obs.cn-north-4.myhuaweicloud.com/obs-mirror-ftp4/database/mysql-5.7.27-aarch64.tar.gz
[root@arm ~]# tar xzvf mysql-5.7.27-aarch64.tar.gz -C /usr/local/
4.配置Mysql
[root@arm ~]# mv /usr/local/mysql-5.7.27-aarch64 /usr/local/mysql
[root@arm ~]# mkdir -p /usr/local/mysql/logs
[root@arm ~]# chown -R mysql:mysql /usr/local/mysql
[root@arm ~]# ln -sf /usr/local/mysql/my.cnf /etc/my.cnf
[root@arm ~]# cp -rf /usr/local/mysql/extra/lib* /usr/lib64/
[root@arm ~]# mv /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6.old
[root@arm ~]# ln -s /usr/lib64/libstdc++.so.6.0.24 /usr/lib64/libstdc++.so.6
# 设置开机启动
[root@arm ~]# cp -rf /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@arm ~]# chmod +x /etc/init.d/mysqld
[root@arm ~]# systemctl enable mysqld
5. 添加环境变量
[root@ecs-arm ~]# vi /etc/profile
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin
5. 初始化启动mysql
方式一：无密码初始化登录
-------------------------------
[root@ecs-arm ~]# mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
[root@ecs-arm ~]# systemctl start mysqld
[root@ecs-arm ~]# systemctl status mysqld
# 设置数据库root的密码
[root@ecs-arm ~]# mysql_secure_installation
方式二：随机密码初始化登录
# "–initialize"生成随机密码，在这里存储在/usr/local/mysql/logs/mysql-error.log
[root@ecs-arm ~]# mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
[root@ecs-arm ~]# systemctl start mysqld
[root@ecs-arm ~]# systemctl status mysqld
# 查看随机密码
[root@ecs-arm ~]# cat /usr/local/mysql/logs/mysql-error.log | grep password
如无法正常获取密码进行登录，请访问另一篇文章：mysql5.7.22以上版本忘记密码时这样找回
