1、 首先从httpd开始，先卸载在安装倒是比较容易，不过后来像添加ssl功能，发现编译的时候需要用openssl的安装目录，本人比较愚笨，一顿好找也没有找到，于是就想把openssl也以源代码方式安装。先卸载，此时出现问题，系统好多东西依赖于openssl的库，我查了好多资料也没找到什么办法，于是我最后一狠心，用rpm -e --nodeps给卸载了，然后手动安装了openssl，然后重新启动，这下坏了，好多服务都起不来了，smb,ssh等等，图形模式也起不来了，我欲哭无泪。
2、 因为我是在虚拟机上安装的，smb起不来了，我只能重新安装系统了。这次安装我大多数东西都没选择，一路安装完毕，结果在文本方式发现vi编辑没有颜色了，哎，也不知道是少装了那个东西弄得，只能按照猜测重新安装了又添加了一些东西。不过幸运的vi高亮显示功能又有了，遗憾的是具体是那个软件我还是不清楚。有了上次的教训我不敢轻易卸掉系统原来的openssl了，l。步骤简介如下（怕以后忘了）
3、 安装zlibHome :http://www.gzip.org/zlib/Package(linux source) :http://www.gzip.org/zlib/Our ConfigurationInstall to : /usr/localModule types : dynamically and staticly loaded modules, *.so and *.aBuild Instructionszlib library files are placed into /usr/local/lib and zlib header files are placed into /usr/local/include, by default.Build static libraries
4、.../zlib-1.2.1]# ./configure.../zlib-1.2.1]# make test.../zlib-1.2.1]# make installBuild shared libraries.../zlib-1.2.1]# make clean.../zlib-1.2.1]# ./configure --shared.../zlib-1.2.1]# make test.../zlib-1.2.1]# make install.../zlib-1.2.1]# cp zutil.h /usr/local/include.../zlib-1.2.1]# cp zutil.c /usr/local/include/usr/local/lib should now contain...

6、 安装opensslDownloadHome :http://www.openssl.org/Package(source) :openssl-0.9.7d.tar.gzOur Configurationinstall to : /usr/local/sslmodule types : dynamically and staticly loaded modules, *.so *.aBuild Instructions.../openssl-0.9.7d]# ./config--prefix=/usr/local/ssl[default location]
7、shared[in addition to the usual static libraries, create shared libraries]zlib-dynamic[like "zlib", but has OpenSSL load the zlib library dynamically when needed].../openssl-0.9.7d]# ./config -t[display guess on system made by ./config].../openssl-0.9.7d]# make.../openssl-0.9.7d]# make test.../openssl-0.9.7d]# make install
8、Update the Run-time Linkerld.so.cache will need to be updated with the location of the new OpenSSL shared libs: libcrypto.so.0.9.7 and libssl.so.0.9.7Sometimes it is sufficient to just add these two files to /lib, but we recommend you follow these instructions instead.Edit /etc/ld.so.confAdd/usr/local/ssl/libto the bottom....]# ldconfigUpdate the PATH
