Linux系统下安装包制作

 

本文以OpenDDS开源代码为例，编写Linux的bin安装包制作流程及详细代码，将已经搭建好的DDS环境打包制作成bin安装包，在目标Linux系统上，直接安装(免予多次编译)，即可使用。

前提是有一个已经搭建好的OpenDDS环境，关于Linux系统下DDS编译方法请参考前一博文：Linux下OpenDDS环境搭建

bin安装包的制作思想：

将安装脚本install.sh和源码包打成一个bin文件，当在命令行运行bin安装文件时，其实就是运行bin里面的install.sh来解压bin中的tar.gz的过程。

安装脚本install.sh和打包脚本auto_package.sh的具体代码如下：

1、install.sh，内容如下：

#!/bin/bash

PATH=/usr/bin:/bin

 

ProductName="OpenDDS"

ProductVer="3.5"

AppFolder="/usr"

InstallPath=

 

TAR_NAME="$ProductName$ProductVer.tar.gz"

 

#打印许可

function printLicense() {

    more <<"EOF"

     

      License Agreement

    .............

EOF

 

read -p "Do you agree to the above license terms? [y/n]:" reply leftover

case $reply in

    y* | Y*)

          echo "You have agreed to the license, install start...";;

      n* | N*)

          echo "You don't agreed to the license, you can't install $ProductName$ProductVer."

           exit 1;;

      *)

           echo "Invalid select, exit install ."

           exit 1;;

      esac

}

 

#版本号比较

function VersionComp() {

    if [ "$1" = "$2" ]; then

          echo "eq"

      else

          lrel=`printf "%s\n%s\n" $1 $2 | \

               sort -t . -k 1,1n -k 2,2n -k 3,3n -k 4,4n -k 5,5n | \

                 head -1`

           if [ "$1" = "${lrel}" ]; then

               echo "lt"

           else

               echo "gt"

           fi

      fi

}

 

#软件版本号检测

function VersionCheck() {

    DDS_ROOT=${DDS_ROOT}

      VersionFile=$DDS_ROOT/VERSION

      if [ -e $VersionFile ]; then

          Version=`head -1 $VersionFile | awk '{print $5}' | cut -d"," -f1`

           if [ "gt" = $(VersionComp "$Version" "$ProductVer") ]; then

               echo "Newer version ($Version) is already installed, please uninstall first!"

                 exit 1

           else

               read -p "Older version ($Version) is already installed, upgrade to $ProductVer? [y/n]:" reply leftover

                 case $reply in

                y* | Y*)

                          ;;

                      n* | N*)

                         echo "You don't agreed to the license, you can't install $ProductName$ProductVer."

                            exit 1;;

                      *)

                         echo "Invalid select, exit install ."

                       exit 1;;

              esac

           fi

      fi

}

 

#设置安装路径

function SetInstallPath() {

    read -p "Install $ProductName$ProductVer to $AppFolder, sure? [y/n]:" reply leftover

      case $reply in

    y* | Y*)

          ;;

      n* | N*)

          read -p "Please input install path: " AppFolder leftover;;

      *)

           echo "Invalid select, exit install ."

           exit 1;;

      esac

     

      AppFolder=`readlink -f $AppFolder`

      InstallPath=$AppFolder/

      mkdir -p $InstallPath

}

 

#文件校验

function CheckSum() {

    if [ ! -x /usr/bin/sum ]; then

          echo "Can't find /usr/bin/sum to do checksum, continuing anyway."

           return 0

      fi

 

      echo "Checksumming..."

      sumret=(`/usr/bin/sum $TAR_NAME`)

      if [ ${sumret[0]} != sum_value -o ${sumret[1]} != sum_size ]; then

          echo "The install file appears to be corrupted."

        echo "Please do not attempt to install this file."

           exit 1;

      fi

}

 

#解包

function Unpack() {

    echo "Unpacking..."

      lines=`awk '/^exit 0/print NR+1;exit 1;}' "$0"`

      tail -n +$lines "$0" > $TAR_NAME      2>/dev/null

     

      CheckSum

     

      tar -zvxf $TAR_NAME -C $InstallPath/  2>/dev/null

     

      rm $TAR_NAME

}

 

#写环境变量

function WriteEnv() {

    echo "

export DDS_ROOT=$InstallPath/$ProductName$ProductVer/DDS

export PATH=\$DDS_ROOT/bin:\$PATH

export LD_LIBRARY_PATH=\$DDS_ROOT/lib:\$LD_LIBRARY_PATH

" >>　~/.bashrc

    echo "Please restart, to make environment variable effect."

}

 

VersionCheck

printLicense

SetInstallPath

Unpack

WriteEnv

 

echo "Install complete!"

exit 0

 

2、auto_package.sh，内容如下：

#!/bin/bash

PATH=/usr/bin:/bin

 

ProductName="OpenDDS"

ProductVer="3.5"

 

DDS_ROOT=${DDS_ROOT}

DDS_SRC="$ProductName$ProductVer/"

 

#拷贝源码目录构建安装目录

rm    -rf $DDS_SRC

mkdir -p  $DDS_SRC

cp    -r  $DDS_ROOT $DDS_SRC

 

#删除多余的文件和目录

find  ./  -name *.sln             -exec rm -r {} \;

find  ./  -name *vcproj*          -exec rm -r {} \;

find  ./  -name *vcxproj*         -exec rm -r {} \;

find  ./  -name .obj      -type d -exec rm -r {} \;

find  ./  -name .shobj    -type d -exec rm -r {} \;

 

TAR_NAME="$ProductName$ProductVer.tar.gz"

Release="$ProductName$ProductVer.bin"

 

#将安装文件打成tar包

rm $TAR_NAME $Release

tar -zcvf $TAR_NAME $DDS_SRC

 

#计算文件校验值并写到安装脚本中

dds_sum=(`/usr/bin/sum $TAR_NAME`)

sum_value=${dds_sum[0]}

sum_size=${dds_sum[1]}

 

cat install.sh | sed -e s/sum_value/$sum_value/ -e s/sum_size/$sum_size/ > temp.bin

 

#将安装脚本和目标文件一起打成bin文件

cat temp.bin $TAR_NAME > $Release

chmod a+x $Release

 

rm -rf $DDS_SRC $TAR_NAME temp.bin

 

3、执行打包脚本：

将第一步和第二步创建的两个脚本文件放在同一目录下，执行auto_packet.sh脚本，就可以自动创建一个OpenDDS的bin安装包了，将打好的安装包OpenDDS3.5.bin拷贝到目标机上，使用./OpenDDS3.5.bin命令即可启动安装。
