心情: 一般
在Linux系统下，需要给已经运行的Apache增加mod_proxy模块，编译的时候应该这样：
apxs -c -i mod_proxy.c proxy_util.c
否则你可能会收到这样的错误信息
[root@server1 proxy]# /apache/httpd/bin/apachectl configtest
httpd: Syntax error on line 58 of /apache/httpd-2.2.3/conf/httpd.conf: Cannot load /apache/httpd-2.2.3/modules/mod_proxy.so into server: /apache/httpd-2.2.3/modules/mod_proxy.so: undefined symbol: proxy_lb_workers
如果你还加载了mod_proxy_ajp.so那应该
apxs -c -i mod_proxy_ajp.c ajp*.c[root@server1 proxy]# /apache/httpd/bin/apachectl configtest
httpd: Syntax error on line 58 of /apache/httpd-2.2.3/conf/httpd.conf: Cannot load /apache/httpd-2.2.3/modules/mod_proxy_ajp.so into server: /apache/httpd-2.2.3/modules/mod_proxy_ajp.so: undefined symbol: ajp_msg_reset
