自己开发shell脚本实现一键化安装。

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：

　　

 #!/bin/sh
 menu ( ){

 cat<<END
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:
 END

 }
 menu
 read num
 echo "you choice $num"
 if [ "$num" -eq  ]
       then
         echo "begin install lamp"
         /bin/sh /server/scripts/test///install-lamp.sh
         if  [ $? -eq  ]
             then
                 echo "lamp is been install"
                 exit
          else
                 echo "lamp install error"
                 exit
         fi
     elif [ "$num" -eq  ]
       then
         echo "begin install lamp"
         /bin/sh /server/scripts/test///install-lnmp.sh
         if  [ $? -eq  ]
              then
                 echo "lnmp is been install"
                 exit
          else
                 echo "lnmp install error"
                 exit
         fi

     elif [ "$num" -eq  ]
         then
         echo "logout"
         exit
     fi
 fi   

部署方法1

　　测试：

　　

　　

 [root@localhost script]# sh manu.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 begin install lamp
 /bin/sh: /server/scripts/test///install-lamp.sh: 没有那个文件或目录
 lamp install error
 [root@localhost script]# sh manu.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 begin install lamp
 /bin/sh: /server/scripts/test///install-lnmp.sh: 没有那个文件或目录
 lnmp install error
 [root@localhost script]# sh manu.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 logout

 #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。

测试

　   部署方法2：

　　

 #!/bin/sh
 menu ( ){  

 cat<<END
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:
 END

 }
 menu
 read num
 echo "you choice $num"

 function lamp(){
         if [ "$num" -eq  ]
                 then
                         echo "begin install lamp"
                         /bin/sh /server/scripts/test///install-lamp.sh
                 if  [ $? -eq  ]
                          then
                          echo "lamp is been install"
                          exit 

                 else
                         echo "lamp install error"
                         exit
                 fi
         fi
 }

 function lnmp(){
         if [ "$num" -eq  ]
                 then
                         echo "begin install lamp"
                         /bin/sh /server/scripts/test///install-lnmp.sh
                 if  [ $? -eq  ]
                         then
                                 echo "lnmp is been install"
                                 exit
                  else
                         echo "lnmp install error"
                         exit
                 fi
         fi
 }
 function quit(){
         if [ "$num" -eq  ]
                 then
                         echo "logout..."
                         exit
         fi
 }
 case $num in
         )
         lamp
 ;;
         )
         lnmp
 ;;
         )
         quit
 ;;

         *)
         echo "USAG:start|stop|restart|status"
 esac 

部署方法2

　　测试：

　　

　　

 [root@localhost script]# sh  manu2.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 begin install lamp
 /bin/sh: /server/scripts/test///install-lamp.sh: 没有那个文件或目录
 lamp install error
 [root@localhost script]# sh  manu2.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 begin install lamp
 /bin/sh: /server/scripts/test///install-lnmp.sh: 没有那个文件或目录
 lnmp install error
 [root@localhost script]# sh  manu2.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:

 you choice
 logout...
 [root@localhost script]# sh  manu2.sh
         .[install lamp]
         .[install lnmp]
         .[exit]
         pls input the num that you want:
 asdf
 you choice asdf
 USAG:start|stop|restart|status

方法2测试

　　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：

　　

　　

 #!/bin/sh
 #############################################
 # this script is created by xuxuedong.                                   #
 # e_mail:@qq.com                                              #
 # qqinfo:                                                           #
 # This install LAMP  for auto.                                                #
 # version:1.1                                                                     #
 #############################################
 . /etc/init.d/functions
 #set env
 export PATH=$PATH:/bin:/sbin:/usr/sbin
 export LANG="zh_CN.GB18030"
 ####define CMD  and INstall_path
 Instal_path=/application/
 APP_PACKAGE_PATH=/home/tools
 HTTP_RPM=`rpm -qa http*`
 mkdir -p ${Instal_path}
 if [ `$HTTP_RPM|wc -l` -gt  ]
         then
                 for n in $HTTP_RPM;do rpm -e --nodeps $n;done
         else
                 echo "begin install LAMP."
 fi
 if [ ! -e ${APP_PACKAGE_PATH} ]
         then
                 mkdir ${APP_PACKAGE_PATH}
         else
                 yum install gcc* -y
                 cd ${APP_PACKAGE_PATH}
                 wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.32.tar.gz
 fi

 if [ $? -eq  ]
         then
                 tar -zxf  httpd-2.2..tar.gz
         if [ $? -eq  ]
                 then
                         cd httpd-2.2.
                         ./configure --prefix=/application/apache.2.2. --enable-expires --enable-headers --enable-modules=most --enable-so --with-mpm=worker --enable-deflate --enable-rewrite
         fi
         if [ $? -eq  ]
                 then
                         make
                         make install
         fi
         if [ $? -eq  ]
                 then
                         ln -s /application/apache.2.2. /application/apache
         fi
 fi

以安装apache为例子

　　 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。
