香港云服务器的MySQL数据库的安装部署：
1 单节点部署
1.1 tar.gz包安装方式
1）安装依赖
yum -y install gcc glibc libaio libstdc++ libstdc libncurses ld-linux
2）准备软件包，解压
tar -xvf Percona-Server-5.7.19-17-Linux.x86_64.ssl101.tar.gz -C /usr/local/
3）建立软链接
ln -s /usr/local/Percona-Server-5.7.19-17-Linux.x86_64.ssl101 /usr/local/mysql
4）添加mysql 用户与用户组
groupadd mysql
useradd -r -g mysql mysql
5）修改目录属性权限
chown -R mysql:mysql /usr/local/mysql
6）添加环境变量
echo ‘export PATH=/usr/local/mysql/bin:$PATH’ >> /etc/profile
source /etc/profile
7）创建data和binlog 目录，并修改权限
mkdir -p /mysql/{data,binlog}
chown -R mysql:mysql /mysql/
8）创建配置文件my.cnf
