1. 添加mysql用戶組和mysql用戶，用于隔離mysql進程
   groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql
   2.安裝依賴庫
   yum install -y libaio*
2. 下載解壓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
   cat << EOF > /etc/my.cnf
   [client]
   socket=/tmp/mysql.sock
   port = 3306
   [mysqld]
   user=mysql
   basedir=/usr/local/mysql
   datadir=/usr/local/mysql/data
   pid-file=/usr/local/mysql/data/mysql.pid
   log-error=/usr/local/mysql/data/mysql.err
   EOF

設置開機啟動

cp -rf /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
systemctl enable mysqld
5. 添加環境變量
vim /etc/profile

添加下面兩行代碼：
export MYSQL_HOME=/usr/local/mysql
export PATH=$PATH:$MYSQL_HOME/bin

source /etc/profile
5. 初始化啟動mysql

無密碼初始化登錄

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

開啟mysql

systemctl start mysqld

查看狀態

systemctl status mysqld
登錄到mysql數據庫 #開始安裝的時候不需要密碼，直接就可以登錄
Mysql -u root
修改密碼
set password = password('1qaz@WSX');
設置所有人訪問權限
GRANT ALL PRIVILEGES ON . TO 'root'@'%' IDENTIFIED BY '1qaz@WSX' WITH GRANT OPTION;
FLUSH PRIVILEGES;
