PHP module installation in Apache

PHP's website: http://php.net
PHP5 version of the Discuz this forum support parsing, there is good compatibility, but in PHP7 and later versions of Discuz This forum is not compatible, PHP7 may also be some related software compatibility is not very good

Installing PHP5
Environment: HTTP and MySQL services installed, HTTP and MySQL service installation paths must be specified when installing PHP
First download the corresponding PHP version, here is the download php5.6.37
Unzip PHP and execute the compilation parameters in the extracted directory
Explanation of the compilation parameters:

./configure --prefix=/usr/local/php5 \            指定php安装目录--with-apxs2=/usr/local/httpd/bin/apxs \         指定http目录，编译中可向http配置文件中添加php--with-config-file-path=/usr/local/php/etc \     指定php的配置文件目录--with-mysql=/usr/local/mysql \                  指定mysql的安装目录和mysql的库路径--with-pdo-mysql=/usr/local/mysql \               --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir \                                以下是指定php需要编译支持的函数库--with-gd \ --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-sockets --enable-exif\

Compilation parameters in PHP decompression directory, for errors in compilation, the end of the note is answered

PHP7 Installation

Install PHP7, the compilation process and PHP5 are basically consistent, you need to modify the installation directory and configuration file directory specified PHP5 installation, or the installation PHP7 will be overwritten php5

Problems with PHP compilation

Question one:
PHP compilation installation in the installation of error, according to the error information to find the corresponding installation package, installation package software is generally end with devel, use the Yum Install Library name-devel can install the support library properly

Question two:
Resolution: Error:cannot Find Libmysqlclient_r under/usr/local/mysql.
The following problem solution is present when you configure PHP

checking for MySQL support... yeschecking for specified location of the MySQL UNIX socket...nochecking for MySQL UNIX socket location... noconfigure: error: Cannot find libmysqlclient_r under/usr/local/mysql. Note that the MySQL client library is not bundledanymore!

In fact, this is not related to PHP, it is because when compiling Apache, using the--WITH-MPM module, so you have to compile MySQL when you add--enable-thread-safe-client. Parameters
This is an improvement of PHP5.2, which does not require MySQL to enable security threads before the PHP5.2.0 version. The official introduction to the--enable-thread-safe-client item is as follows: How to build a wire program client library is always thread-safe. The biggest problem is that subroutines that are read from the socket in the net.c are not break-safe. You might want to resolve the problem by interrupting a long-time read of the server with your own alarms. If an interrupt handler is installed for Sigpipe interrupts, the socket processing feature should be thread-safe. supesite/x-to avoid dropping a program when the connection is interrupted, MySQL masks sigpipe on the first call to Mysql_server_init (), Mysql_init (), or mysql_connect (). If you plan to use your own sigpipe handler, you should first call Mysql_server_init () and then install your handler.

There is a second solution is convenient: before compiling, the first to process the MySQL library, the default lookup libmysqlclient_r.so, but MySQL default is libmysqlclient.so, the content is exactly the same, make a link

# cd /usr/local/mysql/lib/mysql/ # ln -s libmysqlclient.so.20.0.0 libmysqlclient_r.so
