安装依赖包。
[ ~]# yum -y install pcre pcre-devel expat-devel
编译apr和apr-util。
[ ~]# ls anaconda-ks.cfg apr-1.6.3.tar.gz apr-util-1.6.1.tar.gz httpd-2.4.29.tar.gz [ ~]# tar xf apr-1.6.3.tar.gz [ ~]# tar xf apr-util-1.6.1.tar.gz [ ~]# cd apr-1.6.3 [ apr-1.6.3]# ./configure --prefix=/usr/local/apr [ apr-1.6.3]# make && make install [ apr-1.6.3]# cd ../apr-util-1.6.1 [ apr-util-1.6.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr && make && make install
编译httpd。
[ apr-util-1.6.1]# cd .. [ ~]# tar xf httpd-2.4.29.tar.gz [ ~]# cd httpd-2.4.29 [ httpd-2.4.29]# ./configure --prefix=/usr/local/apache2 --sysconfdir=/etc/apache --with-z --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-mpm=event --enable-mpms-shared=all [ httpd-2.4.29]# make && make install
[ httpd-2.4.29]# echo "MANPATH /usr/local/apache/man" >>/etc/man.config # 设置man路径。 [ httpd-2.4.29]# echo ‘PATH=/usr/local/apache/bin:$PATH‘ >/etc/profile.d/apache.sh[ httpd-2.4.29]# source /etc/profile.d/apache.sh # 设置PATH环境变量。 [ httpd-2.4.29]# ln -s /usr/include /usr/local/apache2/include # 输出头文件。
三种工作模式:CGI、作为模块加入到apache、fastcgi。最简单的是以模块方式加入到apache,此处演示的是php-fpm管理php-cgi方式。
fastcgi模式的php-cgi,由php-fpm提供服务管理,它会根据配置文件启动一定数量的cgi进程,其默认监听的端口为9000,该服务正常工作需要配置文件。也就是说fastcgi模式的php有两个配置文件,一个是php的配置文件,一个是php-fpm的配置文件。
虽然此处演示的是php-fpm管理方式,但有必要说明下,在Linux中如果模块化安装php,不推荐在使用Apache 2.x中使用线程化MPM(worker和event),而是使用prefork模式的mpm,因为Linux系统的线程设计并不那么完美。所以,如果php和apache在同一台主机上(cgi或者模块化方式安装php的时候),建议httpd使用prefork模型,而不在同一台主机中,建议将php设计为fastcgi的工作模式。而在windows平台中则无需考虑这些问题,因为windows系统是真正意义上的多线程系统。

编译安装php有非常非常多的选项,比httpd还多。可以在解压php后的目录下使用./configure --help
查看。以下是部分选项,其中给出"--enable-XXXX"的选项表示默认是disable的,若要开启,需要在此处手动enable,如果给出的是"--disable-XXXX"表示默认是enable的。
--prefix=PREFIX 【SAPI modules:】 --with-apxs2=FILE Build shared Apache 2.0 Handler module. FILE is the optional pathname to the Apache apxs tool apxs --enable-fpm Enable building of the fpm SAPI executable 【General settings:】 --with-config-file-path=PATH Set the path in which to look for php.ini [PREFIX/lib] --with-config-file-scan-dir=PATH Set the path where to scan for configuration files 【Extensions:】 ####################################################### # --with-EXTENSION=shared[,PATH] # # NOTE: Not all extensions can be build as ‘shared‘. # # Example: --with-foobar=shared,/usr/local/foobar/ # ####################################################### --with-openssl=DIR Include OpenSSL support (requires OpenSSL >= 0.9.6) --enable-mbstring Enable multibyte string support --with-zlib=DIR Include ZLIB support --with-bz2=DIR Include BZip2 support --with-mhash=DIR Include mhash support --with-mcrypt=DIR Include mcrypt support --with-freetype-dir=DIR GD: Set the path to FreeType 2 install prefix --with-jpeg-dir=DIR GD: Set the path to libjpeg install prefix --with-png-dir=DIR GD: Set the path to libpng install prefix --with-libxml-dir=DIR SimpleXML: libxml2 install prefix --enable-sockets Enable sockets support --disable-xml Disable XML support (不写时默认--enable-xml) 【连接数据库:】 --with-mysql=DIR Include MySQL support. DIR is the MySQL base directory, if no DIR is passed or the value is mysqlnd the MySQL native driver will be used --with-mysqli=FILE Include MySQLi support. FILE is the path to mysql_config. If no value or mysqlnd is passed as FILE, the MySQL native driver will be used --with-pdo-mysql=DIR PDO: MySQL support. DIR is the MySQL base directory If no value or mysqlnd is passed as DIR, the MySQL native driver will be used --enable-mysqlnd Enable mysqlnd explicitly, will be done implicitly when required by other extensions 【Zend:】 --enable-maintainer-zts Enable thread safety - for code maintainers only!!
部分选项说明:
(1).以libmysql驱动方式连接mysql(Mariadb),需要提前安装mysql(Mariadb)和mysql-devel(mariadb-devel),并使用"--with-mysql"选项指定mysql安装路径,"--with-mysqli"选项指定mysql_config脚本的路径,"--with-pdo-mysql"选项也指定mysql安装路径。假如mysql安装在/usr/local/mysql下。
./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config
(2).以mysqlnd驱动方式连接mysql,不需要提前安装mysql和mysql-devel,--with-mysql、--with-mysqli和--with-pdo-mysql选项都不需要指定具体路径,只需使用mysqlnd作为这些选项的值即可。
./configure --prefix=/usr/local/php --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
在php 5.3的时候已经支持mysqlnd驱动方式了,在php 5.4的时候mysqlnd已经是默认的配置选项了。建议使用mysqlnd的驱动方式。
由于是配置fastcgi的模式,所以在./configure
的时候将apxs2功能换为"--enable-fpm",并且由于此模式下的php由自己独立的服务来控制进程的生成,所以对于为了支持httpd线程的选项"--enable-maintainer-zts"也去掉。以下是编译安装过程:
