MySQL集群自动安装脚本_MySQL

Mysql集群

　　1. 在MySQL源代码目录下新建脚本 install.sh，把下面的代码添加到这个脚本中：

#!/bin/bash

 

############################################

######### MySQL Server Config ##############

############################################

#Determine to install MySQL server

#"0" means do not install server programs

INST_SERVER=1

#MySQL installation path

INST_PATH="/usr/local/mysql"

#Define the ports of MySQL installation, intput strings of

#PORT with whitespace separated.

#e.g. "3306 3307" means install two MySQL servers:

#     The first server will be installed to $INST_PATH/1 and listen 3306 port.

#     The second server will be installed to $INST_PATH/2 and listen 3307 port.

#     ... ...

INST_PORTS="3306"

#The management server information

MGM_HOST="192.168.1.253"

MGM_PORT="2200"

###########################################

######### MySQL Cluster Config ############

###########################################

#Determine to install cluster

#"0" means do not install cluster programs

INST_CLUSTER=1

#Define COMPUTERs in config.ini, intput strings of HostName with

#whitespace separated.

#The Id attribute is auto increment and start with 1.

#e.g. "192.168.1.253 192.168.252" will generate the following code

#  [COMPUTER]

#    Id=1

#    HostName=192.168.1.253

#  [COMPUTER]

#    Id=2

#    HostName=192.168.1.252

COMPUTERS="192.168.1.253 192.168.1.252"

#Define MGMs in config.ini, intput strings of HostName with whitespace separated.

#e.g. "192.168.1.253 192.168.252" will generate the following code

#  [MGM]

#    HostName=192.168.1.253

#  [MGM]

#    HostName=192.168.1.252

MGMS="192.168.1.253"

#Define DBs in config.ini, intput ids of ExecuteOnComputer with whitespace separated.

#e.g. "1 2" will generate the following code

#  [DB]

#    ExecuteOnComputer=1

#  [DB]

#    ExecuteOnComputer=2

DBS="1"

#Define APIs in config.ini, intput ids of ExecuteOnComputer with whitespace separated.

#e.g. "1 0 1 2" will generate the following code

#  [API]

#    ExecuteOnComputer=1

#  [API]

#  [API]

#    ExecuteOnComputer=1

#  [API]

#    ExecuteOnComputer=2

APIS="1 0 2 2"
