apache重启错误： httpd: Syntax error on line 57 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache2/

在重启apache时出现一下错误：

httpd: Syntax error on line 57 of /etc/httpd/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server: libltdl.so.3: cannot open shared object file: No such file or directory

cannot open shared object file：翻译是“无法打开共享对象文件”

网上找的解决方法：

1、把libltdl.so.3所在目录的文件夹名加入/etc/ld.so.conf文件中！
       libltdl.so.3所在的目录就是/usr/local/lib
      #echo "/usr/local/lib">>/etc/ld.so.conf
      # ldconfig

    重启apache

2、

linux启动apache libltdl.so.3:cannot open shared object file:No such file or directory异常

执行ln -s /usr/local/lib/libltdl.so.3 /usr/lib/libltdl.so.3  即可
