perl模块之Rex（本地安装）

前言

由于环境限制，需要安装的机器不可以上网，如果可以连网，请参考官网文档，以下所有操作都是root（如果没有root，编译的时候需要有一些修改），OS：suse11sp2，其实大部分linux应该都可以。

主要是Net::SSH2模块安装起来很坑,，依赖 libssh2，openssl，zlib ，自己FTP上去编译了一堆，还得参考一些不完全正确的中文blog，还是英文的靠谱一些，ln 一些 动态链接库，最后手动把老的libssh2卸载，安装Net::OpenSSH就没这么多问题。

环境准备

1.perl 5.10.1（假设已安装）3.libssh2、openssl、zlib、expat源码3.Rex模块及依赖的包

编译源码包

如果能连网 用yum 、apt-get或者zypper，下载相应的包和devel包会很方便，当然编译是通吃的。

编译expat

cdtest -f installed/expat-2.0.1.tar.gz && mv installed/expat-2.0.1.tar.gz .test ! -f expat-2.0.1.tar.gz && wget http://download.sf.net/expat/expat-2.0.1.tar.gzmkdir -p -m 0700 srccd srcfind -maxdepth 1 -type d -name "expat-*" -exec rm -r {} \;tar xzvf ~/expat-2.0.1.tar.gzcd expat-2.0.1test $UID = 0 && chown -R root:root ../configure --prefix=/usrmakerm -f /usr/lib/libexpat.*make installldconfig# I had to create a .0 symlink for Firefoxln -s /usr/lib/libexpat.so /usr/lib/libexpat.so.0cdmkdir -p -m 0700 installedrm -f installed/expat-*.tar.*mv expat-2.0.1.tar.gz installed/

编译openssl

编译libssh2

# Get itcdtest -f installed/libssh2-1.4.3.tar.gz && mv installed/libssh2-1.4.3.tar.gz .test ! -f libssh2-1.4.3.tar.gz && wget http://www.libssh2.org/download/libssh2-1.4.3.tar.gz# Extract the sourcemkdir -p -m 0700 srccd srcfind -maxdepth 1 -type d -name "libssh2-*" -exec rm -r {} \;tar xzvf ~/libssh2-1.4.3.tar.gzcd libssh2-1.4.3test $UID = 0 && chown -R root:root .# Configure the build - 64-bittest $(uname -m) = "x86_64" && ./configure --mandir=/usr/local/man --with-libssl-prefix=/usr/local/ssl \ --libdir=/usr/local/lib64# Configure the build - anything elsetest $(uname -m) != "x86_64" && ./configure --mandir=/usr/local/man --with-libssl-prefix=/usr/local/ssl# Build itmake# Install itmake installldconfig# Make sure your non-root user can remove the source laterchown -R $(logname) .chmod -R u+w .# Save the source for latercdmkdir -p -m 0700 installedrm -f installed/libssh2-*.tar.*mv libssh2-1.4.3.tar.gz installed/# add by shalk  ln -s /usr/local/lib64/libssh2.so.1.0.* /usr/lib64/libssh2.so.1 # If you ever want to uninstall libssh2, this should do it:#cd#test -d src/libssh2-* && ( cd src/libssh2-* ; make uninstall )#for pfx in /usr /usr/local;#do#  ( cd ${pfx}/include#    rm -f libssh2.h libssh2_sftp.h libssh2_publickey.h )#  rm -f ${pfx}/lib/libssh2.* ${pfx}/man/man3/libssh2_* \#   ${pfx}/share/man/man3/libssh2_* ${pfx}/lib/pkgconfig/libssh2.pc#  test -d ${pfx}/lib64 &&#   rm -f ${pfx}/lib64/libssh2.* ${pfx}/lib64/pkgconfig/libssh2.pc#done#ldconfig##find ~/src -maxdepth 1 -type d -name "libssh2-*" -exec rm -r {} \;#rm -f ~/installed/libssh2-*.tar.*

至此，openssl，expat，zlib，libssh2就安装好了，主要是他们的动态链接库都可以找到，并且覆盖掉老版本的就好。 为此我卸载了版本的libssh2rpm -e libssh2-1-0.19.0+20080814-2.16.1 --nodeps 其实只要ln -s /usr/local/lib64/libssh2.so.1.0.* /usr/lib64/libssh2.so.1就OK了 因为那个包 只提供了两个文件，用rpm -ql可以查看到。

感谢 jason的howto 提供的编译代码

准备Rex的本地安装库

下载cpanm

#下载了一个单独的cpanm 可执行文件curl -LO http://xrl.us/cpanm

先下载Rex所有的依赖包到dists目录

cpanm -L /dev/null --save-dists dists --scandep Rex

生成索引

cpanm OrePAN#disks的绝对路径orepan_index.pl --repository=/home/path/dists/#生成的文件为/home/path/dists/module/02packages.details.txt.gz

可以将dists目录都copy走。

安装Rex

上传cpanm和dists目录

chmod a+x cpanmcp cpanm /usr/bin/#    从dists目录读依赖包，安装到/usr/local/rex/目录下，安装Rex模块cpanm --mirror-only --mirror file:///root/dists/   -L  /usr/local/rex/  Rex

验证

后记

以后就方便了，把需要用到的打包上传，相关下载 提取密码:o7n7

如果在一台内网机器需要安装

#上传到安装的节点tar -zvxf rex_all.tar.gzcd rex_allsh install.sh#等待编译完成 执行cpanm --mirror-only --mirror file:///root/dists/   -L  /usr/local/rex/  Rex
