1.增加yum數據源
(1.1)從http://dev.mysql.com/downloads/repo/yum/ 獲取合適的數據源
(1.2)安裝數據源包
shell> sudo rpm -Uvh platform-and-version-specific-package-name.rpm
eg:安裝 Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package
shell> wget http://repo.mysql.com/mysql57-community-release-el7-7.noarch.rpm
shell> sudo rpm-Uvh mysql57-community-release-el7-7.noarch.rpm
2.選擇合適的安裝版本
(2.1)查看mysql數據源中存在的包
shell> sudo yum repolist all | grep mysql
(2.2)編輯 /etc/yum.repos.d/mysql-community.repo,啟用相應的mysql版本
# Enable to use MySQL 5.6
[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/7/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
ps: "enabled=1" 啟用,"enabled=0" 禁用,上述配置則是安裝"mysql 5.7",禁用"mysql 5.6"
(2.3)查看mysql啟用列表
shell > sudo yum repolist enabled | grep mysql
mysql-connectors-community/x86_64 MySQL Connectors Community 17
mysql-tools-community/x86_64 MySQL Tools Community 27
mysql57-community/x86_64 MySQL 5.7 Community Server 20
3.安裝mysql
shell> sudo yum install mysql-community-server
注意:在使用yum 安裝 mysql 5.7過程中,會隨機生成一個臨時的root密碼保存到錯誤日志("/var/log/mysqld.log"),可以使用如下命令進行查看:
shell > sudo grep 'temporary password' /var/log/mysqld.log
因此安裝mysql 5.7後,需要盡快修改密碼。
4.啟動mysql服務器
shell> yum --disablerepo=\* --enablerepo='mysql*-community*' list available
(4.1)啟動命令
shell> sudo service mysqld start
(4.2)查看mysql狀態
shell> sudo service mysqld status
5.mysql_secure_installation
使用mysql_secure_installation設置root密碼,刪除匿名用戶等重要操作
shell> mysql_secure_installation
6.安裝mysql額外工具
(6.1)查看可用包名
shell> mysql_secure_installation
(6.2)安裝包
shell> sudo yum install 包名
如:安裝 mysql-workbench-community
shell> sudo yum install mysql-workbench-community
7.升級mysql
(7.1)編輯 /etc/yum.repos.d/mysql-community.repo
(7.2)執行update
shell> sudo yum update mysql-server
或者使用下述命令更新所有包
shell> sudo yum update
8. centos7默認使用mariadb數據庫代替mysql,先將mariadb相關包卸載
(8.1)查詢 maridb 包命令
shell> sudo rpm -qa | grep -i mariadb
(8.2)刪除
shell> sudo rpm -e 相關包名
