CentOS7 yum 安装 mysql5.7
- 下載mysql的yum倉庫文件包??
wget http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql57-community-release-el7-10.noarch.rpm
rpm -ivh mysql57-community-release-el7-10.noarch.rpm
- ?開始使用yum安裝mysql
yum -y install mysql-server
注意：在安裝mysql-server可能會出現以下報錯：
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql Importing GPG key 0x5072E1F5:Userid : "MySQL Release Engineering <mysql-build@oss.oracle.com>"Fingerprint: a4a9 4068 76fc bd3c 4567 70c8 8c71 8d3b 5072 e1f5Package : mysql57-community-release-el7-10.noarch (installed)From : /etc/pki/rpm-gpg/RPM-GPG-KEY-mysqlPublic key for mysql-community-libs-compat-5.7.38-1.el7.x86_64.rpm is not installedFailing package is: mysql-community-libs-compat-5.7.38-1.el7.x86_64GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql這個報錯是指mysql密鑰過期了，需要更新一下密鑰，更新完密鑰之后，重新安裝mysql-server即可。
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
yum -y install mysql-community-server
- 啟動mysql
?systemctl enable mysqld
?systemctl start mysqld
?systemctl status mysqld
?
- 首次安裝后，可以通過mysql日志查詢默認密碼，登錄后修改密碼即可。?
cat /var/log/mysqld.log | grep password
初始密碼登錄后必須先執行修改密碼才能進行其他操作
mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'newpassword';
FLUSH?PRIVILEGES;
quit
- 重啟mysql服務
systemctl restart mysqld
至此通過yum 安裝 mysql完成。
