Linux环境下MySQL（二进制）自动安装脚本

来源：互联网发布：python 二维高斯函数编辑：程序博客网时间：2024/04/29 23:50

说明：

一、本脚本仅供测试使用，若正式环境想要使用，需更改脚本的一些参数。

二、使用本脚本之前，需保证linux环境可以联网下载，若不能联网，则需要将下载好的mysql二进制包上传至linux中的/data目录下。

三、脚本使用是需一次输入三个参数：

1、需安装的mysql版本号，如：5.6.24

2、需安装的mysql端口设置，如：3306

3、mysql的server_id设置，如：1003306

使用步骤：

1、将下列脚本上传至linux环境中，我个人是以mysql_install.sh命名

#!/bin/bash#mysql_install by chen#Email：chenhz1218@gmail.com & 296966488@qq.com#version 2.0#安装版本 5.6.20-5.6.25#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mysqldatamenu="/data"read  -p "Input a mysql version:" -t 30  mysql_versionread  -p "Input a mysql port:" -t 30  mysql_portread  -p "Input a mysql_server_id:" -t 30 mysql_server_idmysqlfile="$datamenu/mysql-$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-$mysql_version-linux-glibc2.5-x86_64.tar.gzelif [ ! -f "$mysqlfile" ];then     wget -P /data  http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-$mysql_version-linux-glibc2.5-x86_64.tar.gzfi#解压下载好的mysqlcd /optmkdir mysqlcd mysqltar zxvf $mysqlfile -C /opt/mysql#创建mysql用户egrep "^mysql" /etc/group >& /dev/nullif [ $? -ne 0 ]then    groupadd mysqlfi#create user if not existsegrep "^mysql" /etc/passwd >& /dev/nullif [ $? -ne 0 ]then    useradd -g mysql -s /sbin/nologin -d /usr/local/mysql mysqlfi#创建mysql软连接，并授权给mysql用户cd /usr/local/rm -rf /usr/local/mysqlln -s /opt/mysql/mysql-$mysql_version-linux-glibc2.5-x86_64 /usr/local/mysqlchown -R mysql:mysql /usr/local/mysqlchown -R mysql:mysql /usr/local/mysql/#基于配置文件，创建mysql安装目录，并授权mkdir -p /data/mysqlmkdir -p /data/mysql/mysql${mysql_port}cd  /data/mysql/mysql${mysql_port}/mkdir /data/mysql/mysql${mysql_port}/datamkdir /data/mysql/mysql${mysql_port}/logsmkdir /data/mysql/mysql${mysql_port}/tmpchown -R mysql:mysql /data/mysql/mysql${mysql_port}cat > /etc/my.cnf << EOF[client]port            = ${mysql_port}socket          = /tmp/mysql.sock# The MySQL server[mysqld]# Basicport            = ${mysql_port}user        = mysqlbasedir         = /usr/local/mysqldatadir         = /data/mysql/mysql${mysql_port}/datatmpdir          = /data/mysql/mysql${mysql_port}/tmpsocket          = /tmp/mysql.socklog-bin     = /data/mysql/mysql${mysql_port}/logs/mysql-binlog-error   = error.logslow-query-log-file = slow.logskip-external-lockingskip-name-resolvelog-slave-updateslower_case_table_names  = 1  #忽略表名大小写character_set_server           = gbk  innodb_file_per_table          = 1  innodb_autoinc_lock_mode       = 2    explicit_defaults_for_timestamp = true  sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES  EOF#初始化mysqlcd /usr/local/mysql./scripts/mysql_install_db --defaults-file=/etc/my.cnf#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

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

2、给脚本赋予可执行权限，

[root@zabbix-server ~]# rz -y z waiting to receive.**B0100000023be50[root@zabbix-server ~]# lsanaconda-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

3、执行脚本，并输入三个参数，等待数据库安装

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

4、启动数据库

[root@MySQL ~]# /etc/init.d/mysql startStarting MySQL..                                           [  OK  ][root@zabbix-server ~]# mysqlWelcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 1Server version: 5.6.24-log MySQL Community Server (GPL)Copyright (c) 2000, 2015, Oracle and/or its affiliates.

至此，linux下mysql安装已经完成，可以使用它做一些测试了
