說明：

一、本指令碼僅供測試使用，若正式環境想要使用，需更改指令碼的一些引數。

二、使用本指令碼之前，需保證linux環境可以聯網下載，若不能聯網，則需要將下載好的mysql二進位制包上傳至linux中的/data目錄下。

三、指令碼使用是需一次輸入三個引數：

1、需安裝的mysql版本號，如：5.6.24

2、需安裝的mysql埠設定，如：3306

3、mysql的server_id設定，如：1003306 

使用步驟：

1、將下列指令碼上傳至linux環境中，我個人是以mysql_install.sh命名

#!/bin/bash
#mysql_install by chen
#Email：[email protected] & [email protected]
#version 2.0
#安裝版本 5.6.20-5.6.25
#安裝要求：
#需要可以聯網，若無網路，可以先建立/data目錄，將安裝包上傳到/data目錄下

#判斷/data目錄是否存在，若不存在則建立，並且下載mysql
datamenu="/data"
read  -p "Input a mysql version:" -t 30  mysql_version
read  -p "Input a mysql port:" -t 30  mysql_port
read  -p "Input a mysql_server_id:" -t 30 mysql_server_id
mysqlfile="$datamenu/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz"

if [ ! -d "$datamenu" ];then
     mkdir  "$datamenu"
     wget -P /data  http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz
elif [ ! -f "$mysqlfile" ];then
     wget -P /data  http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz
fi

#解壓下載好的mysql
cd /opt
mkdir mysql
cd mysql
tar zxvf $mysqlfile -C /opt/mysql

#建立mysql使用者

egrep "^mysql" /etc/group >& /dev/null
if [ $? -ne 0 ]
then
    groupadd mysql
fi

#create user if not exists
egrep "^mysql" /etc/passwd >& /dev/null
if [ $? -ne 0 ]
then
    useradd -g mysql -s /sbin/nologin -d /usr/local/mysql mysql
fi


#建立mysql軟連線，並授權給mysql使用者
cd /usr/local/
rm -rf /usr/local/mysql
ln -s /opt/mysql/mysql-$mysql_version-linux-glibc2.5-x86_64 /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql/

#基於配置檔案，建立mysql安裝目錄，並授權
mkdir -p /data/mysql
mkdir -p /data/mysql/mysql${mysql_port}
cd  /data/mysql/mysql${mysql_port}/
mkdir /data/mysql/mysql${mysql_port}/data
mkdir /data/mysql/mysql${mysql_port}/logs
mkdir /data/mysql/mysql${mysql_port}/tmp
chown -R mysql:mysql /data/mysql/mysql${mysql_port}

cat > /etc/my.cnf << EOF

cd /usr/local/mysql

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql


#新增環境變數，並使/etc/profile環境變數生效
echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
 

<pre name="code" class="plain">export PATH=$PATH:/usr/local/mysql/bin

2、給指令碼賦予可執行許可權，

[root@zabbix-server ~]# rz -y 
z waiting to receive.**B0100000023be50
[root@zabbix-server ~]# ls
anaconda-ks.cfg  install.log  install.log.syslog  mysql_install.sh
[root@zabbix-server ~]# chmod +x mysql_install.sh 
[root@zabbix-server ~]# ls -al|grep mysql_install.sh 
-rwxr-xr-x.  1 root root  3136 Jul 29 10:29 mysql_install.sh
 

[root@MySQL ~]# ./mysql_install.sh 
Input a mysql version:5.6.24
Input a mysql port:3306
Input a mysql_server_id:1003306

4、啟動資料庫

[root@MySQL ~]# /etc/init.d/mysql start
Starting MySQL..                                           [  OK  ]
[root@zabbix-server ~]# mysql

至此，linux下mysql安裝已經完成，可以使用它做一些測試了
