云主机云服务器

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
