关于linux:arm机器上安装mysql57

MySQL 下载地址为：

https://obs.cn-north-4.myhuaw…

1. 增加 mysql 用户组和 mysql 用户，用于隔离 mysql 过程
   groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql
   2. 装置依赖库
   yum install -y libaio*

2. 下载解压 Mysql
   wget https://obs.cn-north-4.myhuaweicloud.com/obs-mirror-ftp4/database/mysql-5.7.27-aarch64.tar.gz
tar xzvf mysql-5.7.27-aarch64.tar.gz -C /usr/local/
   4. 配置 Mysql

    mv /usr/local/mysql-5.7.27-aarch64 /usr/local/mysql
    mkdir -p /usr/local/mysql/logs
    chown -R mysql:mysql /usr/local/mysql 
    ln -sf /usr/local/mysql/my.cnf /etc/my.cnf
    cp -rf /usr/local/mysql/extra/lib* /usr/lib64/ 
    mv /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6.old
    ln -s /usr/lib64/libstdc++.so.6.0.24 /usr/lib64/libstdc++.so.6

   设置开机启动

    cp -rf /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld 
    chmod +x /etc/init.d/mysqld
   systemctl enable mysqld

3. 增加环境变量
   vim /etc/profile

增加上面两行代码：

export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

source /etc/profile

初始化 mysql

mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

开启 mysql

systemctl start mysqld
