MySQL5.7多实例自动化部署脚本

一、安装说明

------------------------------------------------------

mysql5.7.10_onekey_install.sh自动化部署脚本支持mysql5.7.10初始化安装，多实例创建，且使用经过优化后的my.cnf配置文件和mysql.server启动脚本，该SHELL脚本在CentOS6.5_x86_64操作系统测试通过。部署示意图如下：

wKioL1Z5-gmAqQ0GAABewFnc9Ck868.png

1、安装方式

需要准备的文件如下，放到同一个目录下，然后执行shell脚本

执行方式：

./mysql5.7.10_onekey_install.sh 3307 

端口自定义，要求整数，且不和服务器端口冲突

# tree mysql5.7.10_onekey_install

mysql5.7.10_onekey_install

├── my.cnf

├── mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz

├── mysql5.7.10_onekey_install.sh

└── mysql.server

1、如果是首次安装mysql，则会构建所需的所有预安装环境并创建第一个实例；

2、如果不是首次安装mysql，则会在原有基础上创建多实例；

2、安装软件版本

- 操作系统：CentOS6.5_x86_64

- MySQL版本：mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz （最新版本5.7.10）

3、安装目录规划

上传软件包目录：/home/zkyw/install

mysql程序目录：/opt/application/mysql

mysql实例数据文件目录：/data/$Port

4、程序启停操作

启动mysql实例：/data/$Port/mysql.server start

停止mysql实例: /data/$Port/mysql.server stop

查看mysql实例状态：/data/$Port/mysql.server status

5、脚本执行过程

第一步：对传入的参数（端口号）做判断，要求为整数且不能与服务器已有端口号冲突；

第二步：如果服务器还没有安装过mysql，则进行初始化安装，自动配置所需安装环境；

第三步：如果服务器上已经安装了mysql，则会创建多实例；

第四步：初始化安装过程：删除msyql相关的rpm包安装libaio包创建安装所需的用户目录等安装mysql配置mysql

第五步：创建多实例过程：创建目录并授权安装mysql配置mysql

二、自动化部署脚本

# We can't Japanese on normal console atboot time, so force. 

if [ "$LANG" = "ja" -o "$LANG" = "ja_JP.eucJP" ]; then

   if [ "$TERM" = "linux" ] ; then

       LANG=C 

   fi

fi

# Source function library. 

. /etc/init.d/functions

#init

port=3306

mysql_user="root"

mysql_pwd=""

CmdPath=""

mysql_sock=""

#startup function

function_start_mysql()

{

    if [ ! -e "$mysql_sock" ];then

      printf "Starting MySQL...\n"

      ${CmdPath}/mysqld_safe --defaults-file=/data/${port}/my.cnf --ledir=${CmdPath} 2>&1 > /dev/null &

      sleep 2

    else

      printf "MySQL is running...\n"

      exit

    fi

}

#stop function

function_stop_mysql()

       ${CmdPath}/mysqladmin -u ${mysql_user} -p${mysql_pwd} -S $mysql_sock shutdown

       sleep 2

   fi

}

#restart function

function_restart_mysql()

    sleep 2

    function_start_mysql

}

case $1 in

start)
