订阅linux如何卸载openssl
来源：网络收集 点击： 时间：2024-04-19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。
2/8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）
3/8安装zlib
Home :http://www.gzip.org/zlib/
Package(linux source) :http://www.gzip.org/zlib/
Our Configuration
Install to : /usr/local
Module types : dynamically and staticly loaded modules, *.so and *.a
Build Instructions
zlib library files are placed into /usr/local/lib and zlib header files are placed into /usr/local/include, by default.
Build static libraries
4/8.../zlib-1.2.1]# ./configure
.../zlib-1.2.1]# make test
.../zlib-1.2.1]# make install
Build 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...
5/8libz.alibz.so - libz.so.1.2.1libz.so.1 - libz.so.1.2.1libz.so.1.2.1
/usr/local/include should now contain...zconf.hzlib.hzutil.h
Instructions for non-standard placement of zlib
Create the directory that will contain zlib
.../zlib-1.2.1]# mkdir /usr/local/zlib
Follow the given procedure above, except
.../zlib-1.2.1]# ./configure --prefix=/usr/local/zlib
Update the Run-Time Linker
/etc/ld.so.cache will need to be updated with the new zlib shared lib: libz.so.1.2.1
For standard zlib installation...
Add/usr/local/libto /etc/ld.so.conf, if specified path is not present
/etc]# ldconfig
If zlib was installed with a prefix...
Add/usr/local/zlib/libto /etc/ld.so.conf
/etc]# ldconfig
6/8安装openssl
Download
Home :http://www.openssl.org/
Package(source) :openssl-0.9.7d.tar.gz
Our Configuration
install to : /usr/local/ssl
module types : dynamically and staticly loaded modules, *.so *.a
Build Instructions
.../openssl-0.9.7d]# ./config
--prefix=/usr/local/ssl
7/8shared
zlib-dynamic
.../openssl-0.9.7d]# ./config -t
.../openssl-0.9.7d]# make
.../openssl-0.9.7d]# make test
.../openssl-0.9.7d]# make install
8/8Update the Run-time Linker
ld.so.cache will need to be updated with the location of the new OpenSSL shared libs: libcrypto.so.0.9.7 and libssl.so.0.9.7
Sometimes it is sufficient to just add these two files to /lib, but we recommend you follow these instructions instead.
Edit /etc/ld.so.conf
Add/usr/local/ssl/libto the bottom.
...]# ldconfig
Update the PATH
