一、说明在现实环境中可能需要批量部署服务器，那么在我们已经部署好一台服务以后如果实现剩下的服务批量安装呢：
使用shell能否实现功能：
假设我们要部署lamp或者是lnmp如何实现脚本部署？
使用以下代码可实现：
部署方法1：
1 #!/bin/sh 2 menu ( ){ 3 4 cat<<END 5 1.[install lamp] 6 2.[install lnmp] 7 3.[exit] 8 pls input the num that you want: 9 END 10 11 } 12 menu 13 read num 14 echo "you choice $num" 15 if [ "$num" -eq 1 ] 16 then 17 echo "begin install lamp" 18 /bin/sh /server/scripts/test///install-lamp.sh 19 if [ $? -eq 0 ] 20 then 21 echo "lamp is been install" 22 exit 0 23 else 24 echo "lamp install error" 25 exit 0 26 fi 27 elif [ "$num" -eq 2 ] 28 then 29 echo "begin install lamp" 30 /bin/sh /server/scripts/test///install-lnmp.sh 31 if [ $? -eq 0 ] 32 then 33 echo "lnmp is been install" 34 exit 0 35 else 36 echo "lnmp install error" 37 exit 0 38 fi 39 40 elif [ "$num" -eq 3 ] 41 then 42 echo "logout" 43 exit 0 44 fi 45 fi
测试：
1 [root@localhost script]# sh manu.sh 2 1.[install lamp] 3 2.[install lnmp] 4 3.[exit] 5 pls input the num that you want: 6 1 7 you choice 1 8 begin install lamp 9 /bin/sh: /server/scripts/test///install-lamp.sh: 没有那个文件或目录 10 lamp install error 11 [root@localhost script]# sh manu.sh 12 1.[install lamp] 13 2.[install lnmp] 14 3.[exit] 15 pls input the num that you want: 16 2 17 you choice 2 18 begin install lamp 19 /bin/sh: /server/scripts/test///install-lnmp.sh: 没有那个文件或目录 20 lnmp install error 21 [root@localhost script]# sh manu.sh 22 1.[install lamp] 23 2.[install lnmp] 24 3.[exit] 25 pls input the num that you want: 26 3 27 you choice 3 28 logout 29 30 #由于真正的安装脚本没有开发所以每次执行安装都会报错没有文件或者目录，生产环境中将安装脚本写进去可实现一键化安装。
部署方法2：
1 #!/bin/sh 2 menu ( ){ 3 4 cat<<END 5 1.[install lamp] 6 2.[install lnmp] 7 3.[exit] 8 pls input the num that you want: 9 END 10 11 } 12 menu 13 read num 14 echo "you choice $num" 15 16 function lamp(){ 17 if [ "$num" -eq 1 ] 18 then 19 echo "begin install lamp" 20 /bin/sh /server/scripts/test///install-lamp.sh 21 if [ $? -eq 0 ] 22 then 23 echo "lamp is been install" 24 exit 0 25 26 else 27 echo "lamp install error" 28 exit 0 29 fi 30 fi 31 } 32 33 function lnmp(){ 34 if [ "$num" -eq 2 ] 35 then 36 echo "begin install lamp" 37 /bin/sh /server/scripts/test///install-lnmp.sh 38 if [ $? -eq 0 ] 39 then 40 echo "lnmp is been install" 41 exit 0 42 else 43 echo "lnmp install error" 44 exit 0 45 fi 46 fi 47 } 48 function quit(){ 49 if [ "$num" -eq 3 ] 50 then 51 echo "logout..." 52 exit 0 53 fi 54 } 55 case $num in 56 1) 57 lamp 58 ;; 59 2) 60 lnmp 61 ;; 62 3) 63 quit 64 ;; 65 66 *) 67 echo "USAG:start|stop|restart|status" 68 esac
测试：
1 [root@localhost script]# sh manu2.sh 2 1.[install lamp] 3 2.[install lnmp] 4 3.[exit] 5 pls input the num that you want: 6 1 7 you choice 1 8 begin install lamp 9 /bin/sh: /server/scripts/test///install-lamp.sh: 没有那个文件或目录 10 lamp install error 11 [root@localhost script]# sh manu2.sh 12 1.[install lamp] 13 2.[install lnmp] 14 3.[exit] 15 pls input the num that you want: 16 2 17 you choice 2 18 begin install lamp 19 /bin/sh: /server/scripts/test///install-lnmp.sh: 没有那个文件或目录 20 lnmp install error 21 [root@localhost script]# sh manu2.sh 22 1.[install lamp] 23 2.[install lnmp] 24 3.[exit] 25 pls input the num that you want: 26 3 27 you choice 3 28 logout... 29 [root@localhost script]# sh manu2.sh 30 1.[install lamp] 31 2.[install lnmp] 32 3.[exit] 33 pls input the num that you want: 34 asdf 35 you choice asdf 36 USAG:start|stop|restart|status
经过测试方法2更为优雅，当然其实方法一也能实现方法2中输入错误给个提示。
三、编写一键化安装脚本：
1、LAMP安装这里以只安装apache为例子：
1 #!/bin/sh 2 ############################################# 3 # this script is created by xuxuedong. # 4 # e_mail:365686746@qq.com # 5 # qqinfo:365686746 # 6 # This install LAMP for auto. # 7 # version:1.1 # 8 ############################################# 9 . /etc/init.d/functions 10 #set env 11 export PATH=$PATH:/bin:/sbin:/usr/sbin 12 export LANG="zh_CN.GB18030" 13 ####define CMD and INstall_path 14 Instal_path=/application/ 15 APP_PACKAGE_PATH=/home/tools 16 HTTP_RPM=`rpm -qa http*` 17 mkdir -p ${Instal_path} 18 if [ `$HTTP_RPM|wc -l` -gt 0 ] 19 then 20 for n in $HTTP_RPM;do rpm -e --nodeps $n;done 21 else 22 echo "begin install LAMP." 23 fi 24 if [ ! -e ${APP_PACKAGE_PATH} ] 25 then 26 mkdir ${APP_PACKAGE_PATH} 27 else 28 yum install gcc* -y 29 cd ${APP_PACKAGE_PATH} 30 wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.32.tar.gz 31 fi 32 33 if [ $? -eq 0 ] 34 then 35 tar -zxf httpd-2.2.32.tar.gz 36 if [ $? -eq 0 ] 37 then 38 cd httpd-2.2.32 39 ./configure --prefix=/application/apache.2.2.32 --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-deflate --enable-rewrite 40 fi 41 if [ $? -eq 0 ] 42 then 43 make 44 make install 45 fi 46 if [ $? -eq 0 ] 47 then 48 ln -s /application/apache.2.2.32 /application/apache 49 fi 50 fi
注明在第二项的一键化安装部署的部署脚本路径上/bin/sh /server/scripts/test///install-lamp.sh 给的是实际的脚本路径。
实际路径：
[root@localhost script]# ls | grep lamp
lamp.sh
[root@localhost script]# pwd
/server/script
所以需要将/bin/sh /server/scripts/test///install-lamp.sh修改成/bin/sh /server/script/lamp.sh
测试：
证明已经开始安装。
安装结果已经完成了apache的安装，剩下的mysql和php环境安装也可参考脚本：
备注：以上脚本可根据实际情况优化，例如：不需要在屏幕中输出，只在有报错是输出报错情况，安装完成输出安装成功即可。此部署脚步前期最好是能确定需要那些关联库，执行安装前最好是所有的安装环境已经准备好了。以上脚本只做为参考，部分需要根据实际情况开发脚本。劲量不要照搬。
