apache缺少模块解决方法

找到一台老古董机器

[root@resource conf]# cat /etc/redhat-release
CentOS release 5.6 (Final)

[root@resource conf]# openssl version
OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

[root@resource conf]# ldd --version

　开始的想法很简单，直接把别的机器上mod_ssl.so下载到这个机器上，直接就报错了

[root@resource ~]# service httpd configtest
httpd: Syntax error on line 201 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_ssl.so into server: /lib64/libc.so.6: version `GLIBC_2.7' not found (required by /usr/lib64/libcrypto.so.10)

　然后把libc.so.6和libcrypto.so.10 放进去 依然报错

[root@resource ~]# ldconfig /lib64/libc-2.5.so
ldconfig: /lib64/libc.so.6 is not a symbolic link
ldconfig: /usr/lib64/libcrypto.so.10 is not a symbolic link

[root@resource ~]# ls
ls: error while loading shared libraries: /lib64/libc.so.6: ELF file OS ABI invalid
[root@resource ~]# ln -s /lib64/libc-2.5.so /lib64/lib
Display all 129 possibilities? (y or n)

[root@resource ~]# ln -s /lib64/libc-2.5.so /lib64/libc.so.6

[root@resource ~]# ldconfig -l /lib64/libc-2.5.so

[root@resource ~]# cp /lib64/libc-2.5.so /lib64/libc.so.6

　　这个破玩意简直崩溃，幸亏远程连接没断开，几乎所有命令都不能用了。幸好用这个屌丝的办法解决了

然后换思路，重新编译apache，把prefix目录改成其他的。

　　历史版本下载　　http://archive.apache.org/dist/

./configure --prefix=/usr/local/service/httpd --enable-so --enable-ssl --enable-cgi --enable-rewrite --enable-modules=most --enable-mpms-shared=all --with-zlib --with-pcre --with-apr=/usr/local/service/apr --with-apr-util=/usr/local/service/apr-util --sysconfigdir=/usr/local/service/httpd/conf/

[root@resource modules]# cd /usr/local/service/apache2.2/modules/
[root@resource modules]# ls
httpd.exp

　　what？mod_ssl.so去哪了？各种so去哪了，我明明写的enable-modules。各种修改编译命令。仍然没有。百度一下吧，百度各位大神让用apxs命令编译

[root@resource conf]# /usr/local/service/apache2.2/bin/apxs -a -i -c -L /usr/lib/openssl/engines/lib -c *.c -lcrypto -lssl -ldl

[root@resource modules]# cd /usr/local/service/apache2.2/modules/
[root@resource modules]# ls
httpd.exp  mod_ssl.so

　　激动人心的时刻到了，把mod_ssl.so复制到原来apache模块目录/etc/httpd/modules

[root@resource modules]# service httpd configtest
Syntax OK

　　完美
