环境

方法1：在线采用官方YUM方式安装MySQL5.7

如需要安装其他版本只需要修改mysql-community.repo内容即可。

# 1.设置官方yum源
rpm -ivh https://repo.mysql.com//mysql80-community-release-el6-1.noarch.rpm

# 2.在这里我们选择安装5.7版本，只保留以下内容，其他所有内容删除
vim /vim /etc/yum.repos.d/mysql-community.repo

[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

# 3.开始安装
yum install -y mysql-community-server.x86_64

# 4.启动MySQL数据库
service mysqld start
chkconfig mysqld on
service mysqld status
chkconfig --list mysqld

# 5.修改root密码并登录数据库

sudo grep 'temporary password' /var/log/mysqld.log
mysql -uroot -p
mysql> ALTER USER root@localhost IDENTIFIED BY 'Xiaoliu123!';
mysql> exit;

方法2：用下载好的rpm包离线安装

# 1.上传服务器并安装
yum install -y mysql-community-client-5.7.24-1.el6.x86_64.rpm \
                mysql-community-common-5.7.24-1.el6.x86_64.rpm \
                mysql-community-libs-5.7.24-1.el6.x86_64.rpm \
                mysql-community-libs-compat-5.7.24-1.el6.x86_64.rpm \
                mysql-community-server-5.7.24-1.el6.x86_64.rpm

# 2.启动MySQL数据库
service mysqld start
chkconfig mysqld on
service mysqld status
chkconfig --list mysqld

# 3.修改root密码并登录数据库

sudo grep 'temporary password' /var/log/mysqld.log
mysql -uroot -p
mysql> ALTER USER root@localhost IDENTIFIED BY 'Xiaoliu123!';
mysql> exit;
