发布MySQL集群自动安装脚本1.0

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
#####################################################
## Title: MySQL 4.1 Cluster Installation Script ##
## Version: 1.0 ##

#####################################################
## Installation Guide ##
## 1. Copy the script file into mysql source path ##
## 2. Change script file's permission to 755 ##
## 3. execute it and wait for... ##

######### 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"

######### 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

2. 设置脚本权限，让它可执行：chmod 755 install.sh
3. 执行该脚本：./install.sh 或者 ./install <MySQL安装目录>;
