在新的服务器（centos 6.3）编译安装完php-5.4.8，再配置好php.ini和httpd.conf后，启动apache-2.4.3的时候，命令执行/usr/local/apache2/bin/apachectl start时，提示：

httpd: Syntax error on line 146 of /etc/httpd/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: undefined symbol: zend_parse_parameters

通过搜索发现，说是缺少bison。

如果通过rpm -qa|grep bison发现没有安装bison，安装bison即可。centos可以用yum install bison

但是我发现已经安装了bison-2.4.1。最后实在是没办法了，下载了bison-2.5的rpm包直接安装。

[root@localhost ~]#  wget http://ftp.gnu.org/gnu/bison/bison-2.5.tar.gz [root@localhost ~]#  tar -zxvf bison-2.5.tar.gz [root@localhost ~]#  cd bison-2.5 [root@localhost ~]#  ./configure [root@localhost ~]#  make && make install

再重新编译安装了PHP。然后/usr/local/apache2/bin/apachectl start启动Apache。惊奇的发现可以正常启动了，测试了下PHP网页，可以正常访问。

听说还有别人会报下面这个错误，我也一起写出来。

命令执行/usr/local/apache2/bin/apachectl start时，错误提示如下：

httpd: Syntax error on line 146 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied

这个是由于SELinux保护模式引起的。有2种方法可以解决。

第一种：永久关闭SELinux保护模式（不推荐，给服务器带来风险）

[root@localhost ~]#  vi /etc/selinux/config

将SELINUX=enforcing 改成SELINUX=disabled

保存重启系统。

第二种方法：临时关闭selinux模式

[root@localhost ~]#   setenforce 0 [root@localhost ~]#  chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache/modules/libphp5.so

如果上面的命令报错，可以试试这个chcon -t texrel_shlib_t /usr/local/apache/modules/libphp5.so

如果还有报错，请使用帮助，根据帮助写命令。

[root@localhost ~]#  service httpd restart [root@localhost ~]#  setenforce 1
