RHEL7.6使用RPM方式安装MySQL

1、下载RPM包

wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

# 解压
tar -xvf mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

2、检查环境

# 查看是否安装postfix和mariadb包
rpm -qa | grep postfix
rpm -qa | grep mariadb

# 如果安装则卸载
rpm -e 包名

# 安装net-tools
yum install -y net-tools

3、安装MySQL

# 顺序安装以下四个包
rpm -ivh mysql-community-common-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.22-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.22-1.el7.x86_64.rpm

# 启动MySQL
systemctl start mysqld

# 查看默认密码
grep password /var/log/mysqld.log

# 登录MySQL后修改密码
set password = password('密码');
