本篇內容介紹了“MySQL 自動安裝腳本分享”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓丸趣 TV 小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
環境要求：centos：6.8
MySQL：5.7.20
MySQL 安裝文件名：mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
MySQL 源文件路徑：/usr/local/src
MYSQL 腳本文件：/usr/local/src/install_mysql.sh
1、腳本如下：
#/bin/sh
#px 2017-11-29
#mysql install
#email:kitten-pan@163.com 752684428
#version 2.0
#mysql-version mysql5.7.20
source_path=/usr/local/src
install_path=/usr/local/mysql
install_name=mysql-5.7.20-linux-glibc2.12-x86_64
## 檢測本機環境
env_fun()
{
echo ============ 檢測本機環境,please wait …
username=`cat /etc/passwd |grep mysql|cut -c 1-5`
if [$username = mysql];then
echo MySQL account is exits…
return 10
else
echo mysql account is not exits,ready add…
groupadd mysql
useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql
return 12
fi
}
## 判斷 MySQL 是否安裝
check_fun()
{
rpm_name=`rpm -aq |grep mysql-server`
echo $rpm_name
if [! $rpm_name];then
echo begin check the source install,please wait for a moment…
if [-d $install_path];then
echo source install is exist,quit…
exit 0
else
echo 本機未安裝 MySQL, 稍后為你安裝 …
install_fun
op_fun
fi
else
echo -n rpm MySQL 已經安裝，是否刪除？[yes|no]
read select
if [$select = yes];then
rpm -e $rpm_name –nodeps
rm -rf /var/log/mysqld.log
check_fun
else
exit 0
fi
fi
}
### 安裝 MySQL
install_fun()
{
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
cd $source_path echo 解壓中,please waiting…
tar -zxvf ${install_name}.tar.gz mv $install_name $install_path
## 創建數據目錄
mkdir -pv /data/mysqldata
### 給 MySQL 目錄的 MySQL 賬號權限
cd /usr/local chown mysql.mysql mysql
chown -R mysql.mysql /data/mysqldata
cd $install_path bin/mysqld –initialize –user=mysql –basedir=/usr/local/mysql –datadir=/data/mysqldata

2、執行自動安裝腳本
需要填寫 MySQL 的版本信息、端口信息、serverid 信息等
點擊 (此處) 折疊或打開
sh install_mysql.sh
###==================================================###
###welcome to make install mysql with this script###
###copyright 2013 by px###
###==================================================###
============ 檢測本機環境,please wait …
mysql account is not exits,ready add…
begin check the source install,please wait for a moment…
本機未安裝 MySQL, 稍后為你安裝 …
Input a mysql version:5.7.20
Input a mysql port:3309
Input a mysql_server_id:1
解壓中,please waiting…
3、自動安裝完畢 啟動
# service mysqld restart
MySQL server PID file could not be found! [FAILED]
Starting MySQL…………. [ OK ]
4、登入 MySQL 修改密碼
點擊 (此處) 折疊或打開
[root@ct562 mysqldata]# mysql -uroot -p
Enter password:
