Apache服務啓動報錯
[root@localhost ]# service httpd start
httpd: Syntax error on line 162 of /etc/httpd.conf/httpd.conf: Cannot load modules/mod_dir.so into server: /usr/local/apache2/modules/mod_dir.so: undefined symbol: apr_array_clear
解決辦法：將./configure 選項的--with-apr 替換成--with-included-apr 重新編譯
如果報錯：
configure: error: Bundled APR requested but not found at ./srclib/. Download and unpack the corresponding apr and apr-util packages to ./srclib/.
解決辦法：把apr和apr-util copy到http目錄的srclib下 重新編譯
cp -rp /usr/local/src/apr-1.4.6/ /usr/local/src/httpd-2.4.10/srclib/apr
cp -rp /usr/local/src/apr-util-1.5.1/ /usr/local/src/httpd-2.4.10/srclib/apr-util
之後再重新編譯
ok 可以啓動了
