1.检测系统是否自带安装mysql
yum list installed | grep mysql
2.删除系统自带的mysql及其依赖
yum -y remove mysql-libs.x86_64
3.给CentOS添加rpm源,并且选择较新的源
wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
yum localinstall mysql-community-release-el6-5.noarch.rpm
yum repolist all | grep mysql
yum-config-manager --disable mysql55-community
yum-config-manager --disable mysql56-community
yum-config-manager --enable mysql57-community-dmr
yum repolist enabled | grep mysql
4.安装mysql 服务器
yum install mysql-community-server
5.启动mysql
service mysqld start
6.查看mysql是否自启动,并且设置开启自启动
chkconfig --list | grep mysqld
chkconfig mysqld on
7.mysql安全设置
mysql_secure_installation
8.临时密码
5.7.10现在已经不用mysql_secure_installation命令初始化密码了,
又保存在临时文件里:/var/log/mysqld.log,
可以用grep ‘temporary password‘ /var/log/mysqld.log查找
9.设置外网可访问
GRANT ALL PRIVILEGES ON *.* TO [email protected] IDENTIFIED BY ‘1234567‘ WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO [email protected]"%" IDENTIFIED BY ‘1234567‘ WITH GRANT OPTION;
flush privileges;
