源码编译tomcat
tomcat有三种发现版本，官方默认的有源码包和二进制版本，一些社区或个人开发的rpm版本的包，正常情况下，直接使用二进制版本的，一些特殊的环境或者应用中，我们需要编译符合自己的二进制包，一些大型公司的运维人员会编译适合自己需求的rpm包，放进自己部署的yum仓库中，不管是安装系统还是后期部署都相对简单一些。下面给大家简单的介绍一下把源码包编辑成二进制版本包：
大致步骤如下：
1.安装jdk
2.安装ant
3.下载源码包
4.编译：
4.1:ant download
4.2:ant
4.3:ant –f dist.xml release
4.4: ant -f dist.xml package-tgz
编译完成后在/PATH/output/release/v6.0.37/bin/apache-tomcat-6.0.37.tar.gz 这个包便是我我们需要的软件包，下面具体的操作就像下载二进制版本的包，一般情况下我们直接下载二进制版本的包直接解压即可使用，特殊情况可以自己选择编译
我的操作步骤：
# tar zxf apache-tomcat-6.0.37-src.tar.gz
# cd apache-tomcat-6.0.37-src
# ls

直接贴出配置，可能比较晕，这里我简单的介绍一下吧!
1.下载源码包，解压进入源码包内
cp build.properties.default build.properties
我们可以编译此文件，根据自己的意愿更改任何组建设置
2.执行ant download 下载相关的依赖包，默认下载到/usr/share/java/目录下
# cd /usr/share/java/
# ll

drwxr-xr-x4 root root 4096 Jul1 12:28 commons-daemon-1.0.15
drwxr-xr-x5 root root 4096 Jul1 12:29 commons-dbcp-1.3-src
drwxr-xr-x3 root root 4096 Jul1 12:29 commons-pool-1.5.7-src
drwxr-xr-x2 root root 4096 Jul1 12:29 ecj-4.2.2
drwxr-xr-x 10 root root 4096 Jul1 12:29 nsis-2.46
drwxr-xr-x3 root root 4096 Jul1 12:29 tomcat6-deps
drwxr-xr-x3 root root 4096 Jul1 12:28 tomcat-native-1.1.27
3. 执行ant编译
编译完成后，会在当前目录下生产一个output目录
# cd output/
# ll
total 24
drwxr-xr-x8 root root 4096 Jul1 12:29 build
drwxr-xr-x4 root root 4096 Jul1 12:29 classes
drwxr-xr-x4 root root 4096 Jul1 12:30 deployer
drwxr-xr-x 10 root root 4096 Jul1 12:30 dist
drwxr-xr-x2 root root 4096 Jul1 12:30 manifests
drwxr-xr-x3 root root 4096 Jul1 12:30 release
此时我们再build目录会得到完整的tomcat发现版本
# ll

drwxr-xr-x 2 root root 4096 Jul1 12:30 bin

drwxr-xr-x 2 root root 4096 Jul1 12:29 temp
drwxr-xr-x 7 root root 4096 Jul1 12:30 webapps
4.ant–f dist.xml release 这个命令是：Building a release running tests
5.ant-f dist.xml package-tgz生成一个压缩包，
