制作 JAVA WEB + TOMCAT7.0 RPM 安装包 for centos

1  安装rpmbuild，并配置环境

1.1 首先，你应该检查 rpmbuild 是否已经被安装在你的系统上。你将会利用这个工具从 spec 文件或SRPM组件创建 RPM。要检查它是否被安装了，请执行 rpmbuild --showrc 这个指令。它将会显示一大组数据，把 rpmbuild 所采用的创建环境的细节列明。假若系统输出：$ rpmbuild: command not found，便意味着 rpmbuild 未被安装。你可以用 root 身份执行下列指令，通过 yum 来安装它：

[root@host ~]# yum install rpm-build

1.2要创建一个创建 RPM 的环境，这执行下列两个指令：

[user@hostname ~]$ mkdir -p /usr/src/redhat/{BUILD,RPMS,SOURCES,SPECS,SRPMS}

一般这些目录结构会在/root目录下自动创建

2  RPM相关知识点说明

rpmbuild安装抬会在/root的目录下生成一个rpmbuild的目录,共内部结构如下:

• /root/rpmbuild/BUILD: The directory where the sources are built.
• /root/rpmbuild/RPMS: Contains the directories, one for each architecture, that will receive the binary packages after.
• /root/rpmbuild/RPMS/i586: The directory where rpm packages for i586 processors will be stored.
• /root/rpmbuild/RPMS/x86_64: The directory where rpm packages for AMD64 processors will be stored.
• /root/rpmbuild/RPMS/noarch: Idem for noarch (processor-independant) packages.
• /root/rpmbuild/SOURCES: The source files (mypackage.tar.bz2;.tar.gz  for example).
• /root/rpmbuild/SPECS: The spec files we will have to construct.
• /root/rpmbuild/SRPMS: The source rpm after building.

 Insidethe spec file，请参考：http://wiki.mandriva.com/en/Development/Howto/RPM#Inside_the_spec_file  http://blog.csdn.net/redguardtoo/article/details/1373885

3准备必要的文件

[root@host ~]# mkdir tomcat-myweb-1.0[root@host ~]# mv /root/tomcat /root/tomcat-myweb-1.0

制作.spec文件,例如：tomcat-myweb-1.0.spec

[root@host ~]# vi tomcat-myweb-1.0.specSummary:mywebName:tomcat-mywebVersion:1.0Release:0BuildRoot:%{_tmppath}/%{name}-%{version}-rootSource0:tomcat-myweb-1.0.tar.gzLicense:GPLGroup:Applications/Productivity/vbox%descriptionlosoel myweb RPM package%preprm -rf $RPM_BUILD_DIR/%{name}-%{version}%setup -q%build%installrm -fr $BuildRootmkdir -p    $RPM_BUILD_ROOT/usr/local/mywebcp    -rf * $RPM_BUILD_ROOT/usr/local/mywebif [ ! -d  /usr/local/myweb ]then{  mkdir -p  /usr/local/myweb}fichmod 755 /usr/local/myweb  -Rcp -rf * /usr/local/myweb%files%defattr(-,root,root)/usr/local/myweb%pre%postif [ -d  /usr/local/myweb/ ]then{  bash /usr/local/myweb/preinst}fi%preun  if [ -d  /usr/local/myweb/ ]then{  bash /usr/local/myweb/prerm}fi%cleanrm -fr $BuildRoot

其它辅助脚本: preinst

[root@host ~]# vi preinst#!/bin/bashfunction write_log(){    dateoftod=`date +%Y%m%d`    logfilename="log-myweb-$dateoftod"    if [ ! -d /usr/local/myweb/myweb-logs ]    then    {        mkdir -p /usr/local/myweb/myweb-logs    }    fi    if [ ! -f /usr/local/myweb/myweb-logs/$logfilename ]    then    {        touch /usr/local/myweb/myweb-logs/$logfilename    }    fi    if [ $# -eq 2 ]    then        echo "$(date "+%Y-%m-%d %H:%M:%S") [$0:$1] $2" >>/usr/local/myweb/myweb-logs/$logfilename    elif [ $# -eq 3 ]    then        echo "$(date "+%Y-%m-%d %H:%H:%S") [$0:$1] $2 : $3">>/usr/local/myweb/myweb-logs/$logfilename    else        echo "record log error."      fi    }echo "-------------------------------------------------------------------------"echo "    Welcome install myweb software for cloud platform security system."echo "-------------------------------------------------------------------------"write_log $LINENO "INFO:  install process start."if [ $UID -ne 0 ]then{    write_log $LINENO "FATAL: user privilege error."    echo "Error:Superuser privilege are required to run this script."    exit -1}fiwrite_log $LINENO "INFO: user privilege correct."#1:check mysql installed#3:check JDK 1.6 1.7checkjre=$(java -version  2>&1|grep "java version")if [ "$checkjre" = "" ]then{    write_log $LINENO "FATAL: Please install jre first."    echo "Please install jre first."    exit -1}else{    jre_version=$(java -version 2>&1 | grep "java version" | awk '{print $3}' | tr -d \" | awk '{split($0, array, ".")} END{print array[1]"."array[2]}')    cmp_version="1.6"    result_cmp=$(expr $jre_version \>= $cmp_version)    if [ $result_cmp -eq 0 ]    then    {         write_log $LINENO "FATAL: Jre version too low! Please install version 1.6 or higher."    echo "Jre version too low! Please install version 1.6 or higher."    exit -1}    fi}fi

其它辅助脚本:prerm

[root@host ~]# mkdir prerm#!/bin/bashfunction write_log(){    dateoftod=`date +%Y%m%d`    logfilename="log-myweb-$dateoftod"    if [ ! -d /usr/local/myweb/myweb-logs ]    then    {        mkdir -p /usr/local/myweb/myweb-logs    }    fi    if [ ! -f /usr/local/myweb/myweb-logs/$logfilename ]    then    {        touch /usr/local/myweb/myweb-logs/$logfilename    }    fi    if [ $# -eq 2 ]    then        echo "$(date "+%Y-%m-%d %H:%M:%S") [$0:$1] $2" >>/usr/local/myweb/myweb-logs/$logfilename    else        echo "record log error."      fi}write_log $LINENO "INFO: start uninstall myweb process."if [ $UID -ne 0 ]then{    write_log $LINENO "FATAL: user privilege error."    echo "Error:Superuser privilege are required to run this script."    echo "error">rmlog    exit -1}fi#3 del /usr/local/mywebif [ -d /usr/local/myweb ]then{   write_log $LINENO "delete tomcat-myweb."   rm -rf /usr/local/myweb}fi

将preinst和prerm两个文件移到tomcat-myweb-1.0目录下:

[root@host ~]# mv ./preinst ./tomcat-myweb-1.0[root@host ~]# mv ./prerm ./tomcat-myweb-1.0

打包tomcat-myweb-1.0.tar.gz

[root@host ~]#tar –zcvf tomcat-myweb-1.0.tar.gz ./tomcat-myweb-1.0

将tomcat-myweb-1.0.tar.gz移到rpmbuild的SOURCES目录下:

[root@host ~]#mv tomcat-myweb-1.0.tar.gz ./rpmbuild/SOURCES

将tomcat-myweb-1.0.spec文件移到rpmbuild的SPECS目录下

[root@host ~]# mv ./tomcat-myweb-1.0.spec ./rpmbuild/SPECS

4 运行rpmbuild命令，完成RPM包的制作

[root@host~]#rpmbuild –ba ./rpmbuild/SPECS/tomcat-myweb-1.0.spec

5 如果成功，则rpm包会存储在/root/rpmbuild/RPMS  子目录内

注意：

1 如果想在运行安装rpm时，即（rpm-ivh xxxxxxxxxxx.rpm）与用户进行提示交互,必须要在.spec文件的  ’  %post ‘ 阶段调用shell脚本:

2 如果想在运行删除rpm时，即（rpm -e xxxxxxxxxxx）与用户进行提示交互,必须要在.spec文件的  ’ %preun‘阶段调用shell脚本。
