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

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
