在CentOS 7.0 上安裝 MySQL 5.5 步驟如下:

1. 官網下載MySQL 5.5的rpm包,本文以5.5.52為例:

wget https://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-5.5.52-1.el7.x86_64.rpm-bundle.tar

2. 解壓并安裝rpm包:

tar xf MySQL-5.5.52-1.el7.x86_64.rpm-bundle.tar
yum install MySQL-server-5.5.52-1.el7.x86_64.rpm MySQL-client-5.5.52-1.el7.x86_64.rpm MySQL-devel-5.5.52-1.el7.x86_64.rpm -y

3. 啟動mysql服務:

systemctl start mysqld.service

4. 初次啟動mysql服務,獲取初始隨機密碼:

grep "temporary password" /var/log/mysqld.log

5. 登錄mysql:

mysql -u root -p

6. 輸入上一步獲取的臨時密碼,進入mysql命令行,修改密碼:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('your-new-password');

7. 測試連接:

mysql -u root -p

至此,MySQL 5.5已安裝成功。
