[root@localhost ~]# cd /usr/local/src[root@localhost src]# wget http://cn2.php.net/distributions/php-5.6.30.tar.bz2（过程省略）[root@localhost php-5.6.30]# tar jxvf php-5.6.30.tar.bz2[root@localhost src]# cd php-5.6.30/[root@localhost src]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif（过程省略）
--prefix
指定安装目录
--with-apxs2
apache的工具，能让不用人工干涉，自动把扩展模块放置到apache的module里，并在配置文件里加上load modules，httpd-M能把模块加载
--with-config-file-path
指定配置文件所在路径，php.ini
--with-mysql
--with-pdo-mysql
--with-mysqli
指定mysql的路径，三种不同mysql的驱动
（老版本用--with-mysql，新版本用--with-mysqli，作用是一样的）
--with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2
--with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
指定一些php的模块（直接复制使用）
[root@localhost php-5.6.30]# make
（过程省略）
[root@localhost php-5.6.30]# make install
（过程省略）
[root@localhost php-5.6.30]# ls /usr/local/php/bin/pear peardev pecl phar phar.phar php php-cgi php-config phpize
二进制文件，/usr/local/php/bin/php
[root@localhost php-5.6.30]# /usr/local/php/bin/php -m（apache -M）[PHP Modules]bz2CorectypedatedomeregexiffileinfofiltergdhashiconvjsonlibxmlmbstringmcryptmysqlmysqliopensslpcrePDOpdo_mysqlpdo_sqlitePharposixReflectionsessionSimpleXMLsoapsocketsSPLsqlite3standardtokenizerxmlxmlreaderxmlwriterzlib[Zend Modules]
[root@localhost php-5.6.30]# /usr/local/apache2.4/bin/httpd -M
（php是作为httpd的扩展模块的形式存在的）
·模块文件：libphp5.so
[root@localhost php-5.6.30]# ll /usr/local/apache2.4/modules/libphp5.so-rwxr-xr-x. 1 root root 37752768 2月 28 23:19 /usr/local/apache2.4/modules/libphp5.so
·配置文件：
[root@localhost php-5.6.30]# vi /usr/local/apache2.4/conf/httpd.conf
配置文件httpd.conf中，可以看到php5模块，不用则注释掉，随用随取
[root@localhost php-5.6.30]# /usr/local/php/bin/php -i
可以查看配置参数、configuration file的路径等
[root@localhost php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini
·安装常见错误：
1，解决php编译报错configure: error: xml2-config not found. Please check your libxml2 installation
yum install -y libxml2-devel
2，解决php编译报错configure: error: Cannot find OpenSSL's <evp.h>
yum install -y openssl-devel
3，解决php编译报错configure: error: Please reinstall the BZip2 distribution
yum install -y bzip2-devel
4，解决php编译报错configure: error: jpeglib.h not found.
yum install -y libjpeg-devel
5，解决php编译报错configure: error: png.h not found.
yum install -y libpng-devel
6，解决php编译报错configure: error: freetype-config not found.
yum install -y freetype-devel
7，解决php编译报错configure: error: mcrypt.h not found. Please reinstall libmcrypt.
yum install -y epel-release（先安装扩展源，mcrypt在扩展源中）
yum install -y libmcrypt-devel
11.13 安装PHP7
[root@localhost php-5.6.30]# cd /usr/local/src/[root@localhost src]# wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2--2018-02-28 23:52:39-- http://cn2.php.net/distributions/php-7.1.6.tar.bz2正在解析主机 cn2.php.net (cn2.php.net)... 123.125.23.171, 123.125.23.169, 123.125.23.168, ...正在连接 cn2.php.net (cn2.php.net)|123.125.23.171|:80... 已连接。已发出 HTTP 请求，正在等待回应... 200 OK长度：15732452 (15M) [application/octet-stream]正在保存至: “php-7.1.6.tar.bz2”100%[================================================================================================>] 15,732,452 9.45MB/s 用时 1.6s2018-02-28 23:52:41 (9.45 MB/s) - 已保存 “php-7.1.6.tar.bz2” [15732452/15732452])[root@localhost src]# tar jxvf php-7.1.6.tar.bz2[root@localhost src]# cd php-7.1.6/[root@localhost php-7.1.6]# ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
（区别于PHP5：--prefix=/usr/local/php7，--with-config-file-path=/usr/local/php7/etc，没有--with-mysql）
（过程省略）
[root@localhost php-7.1.6]# make && make install
（过程省略）
·PHP7模块文件
[root@localhost php-7.1.6]# ll /usr/local/apache2.4/modules/libphp7.so-rwxr-xr-x. 1 root root 38369056 3月 1 00:05 /usr/local/apache2.4/modules/libphp7.so
·PHP7加载的模块：
[root@localhost php-7.1.6]# /usr/local/php/bin/php -m[PHP Modules]bz2CorectypedatedomeregexiffileinfofiltergdhashiconvjsonlibxmlmbstringmcryptmysqlmysqliopensslpcrePDOpdo_mysqlpdo_sqlitePharposixReflectionsessionSimpleXMLsoapsocketsSPLsqlite3standardtokenizerxmlxmlreaderxmlwriterzlib[Zend Modules]
·apache加载了几个PHP：
[root@localhost php-7.1.6]# /usr/local/apache2.4/bin/apachectl -M
·选择使用的PHP：
（用哪个就留着，不用哪一个就注释掉）
