2、随意创建一个存放MySQL压缩包的目录，如/data

[root@mysql01 yum.repos.d]# mkdir -p /data

3、上传mysql-5.7.15-linux-glibc2.5-x86_64.tar.gz 、一键安装脚本(mysql_install_5.7_v2.sh)到/data目录。(如果服务器可以访问互联网只需要上传mysql_install_5.7_v2.sh脚本赋予权限后执行即可)

#!/bin/sh

#mysql_install by James

#version2.0#安装版本5.7#安装要求：

#需要可以联网，若无网络，可以先创建/data目录，将安装包上传到/data目录下

#判断/data目录是否存在，若不存在则创建，并且下载mysql

read-p "Input a mysql port:" -t 120mysql_port

read-p "Input a mysql_server_id:" -t 120mysql_server_id

read-p "Input a mysql_server_Memory(GB):" -t 120mysql_server_Memory

memory_all=${mysql_server_Memory}var=2innodb_memory=$[$memory_all/$var]

mysqlfile="$datamenu/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz"

if [ ! -d "$datamenu"];then

mkdir"$datamenu"wget-P /data http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz

elif [ ! -f "$mysqlfile"];then

wget-P /data http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gz

#初始化mysql

cd/usr/local/mysql

./bin/mysqld --initialize-insecure

#在/etc/init.d下创建mysql 启动脚本

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

#添加环境变量，并使/etc/profile环境变量生效

echo"export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile && source /etc/profile

mysql_install_5.7_v2.sh

4、赋予安装脚本操作权限。

chmod +x mysql_install_5.7_v2.sh

5、执行一键安装脚本。

sh mysql_install_5.7_v2.sh

6、根据提示输入对应参数，参考如下：

1)版本号根据你下载的版本面定

2)端口号默认是3306

3)Server_ID ：3306+IP最后一个数字

4)输入服务器内存，以GB为单位输入如：我的服务器为6G输入6即可

7、启动MySQL

[root@mysql01 data]# /etc/init.d/mysql status

MySQL is not running, but PID file exists                  [FAILED]

[root@ mysql01 data]# /etc/init.d/mysql start

Starting MySQL                                             [  OK  ]

8、登录MYSQL， 修改ROOT密码。第一次登录是不需要密码的。 这样MYSQL就安装成功了。

执行前source 一下：

[root@mysql01 local]#source /etc/profile

[root@mysql01 local]# mysql -uroot -p

Enter password:
