1.云硬盘挂载

# 查看挂盘名称
fdisk -l# 创建物理卷
pvcreate /dev/vdb# 创建卷组
vgcreate data_vg /dev/vdb# 创建逻辑卷
lvcreate -l +100%free -n data data_vg# 格式化磁盘
mkfs.xfs /dev/data_vg/data# 创建挂载目录
mkdir -p /data1# 挂载
mount /dev/data_vg/data /data1# 添加挂载信息
echo "/dev/mapper/data_vg-data /data1 xfs     defaults        0 0" >> /etc/fstab

2.系统配置

# 关闭防火墙
systemctl stop firewalld# 设置防火墙开机不启动
systemctl disable firewalld# 配置SELINUX
sed -i 's/SELINUX=.*/SELINUX=disabled/g' /etc/selinux/config# 重启
reboot# 卸掉自带的mariadb
yum -y remove mariadb*

3.MySQL安装

# 安装MySQL
rpm -Uvh Percona-Server-client-57-5.7.34-37.1.el7.x86_64.rpm \Percona-Server-server-57-5.7.34-37.1.el7.x86_64.rpm \Percona-Server-shared-57-5.7.34-37.1.el7.x86_64.rpm \Percona-Server-shared-compat-57-5.7.34-37.1.el7.x86_64.rpm# 创建数据目录
