3.安装PHP5和PHP7
安装PHP5
11.10~11.2 安装PHP5
1.下载PHP5安装包并解压
#cd /usr/local/src/
# wget http://cn2.php.net/distributions/php-5.6.30.tar
# tar -xjf php-5.6.30.tar.bz2
这个路径解压处理虽然不报错，但是没有解压过程，echo查看不报错。==--因为这里没有-v==
#cd /usr/local/src/
# wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
#tar zxvf php-5.6.30.tar.gz
2 配置安装
# cd php-5.6.30/
#./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
参数说明：
–prefix=/usr/local/php 指定的安装目录；
–with-apxs2=/usr/local/apache2/bin/apxs 该文件是Apache的一个工具，可以将扩展模块添加到Apache的module文件；
–with-config-file-path=/usr/local/php/etc 指定配置文件所在路径；
–with-mysql=/usr/local/mysql 指定mysql的路径；
–with-mysqli=/usr/local/mysql/bin/mysql_config
–with-pdo-mysql=/usr/local/mysql –with-mysqli=/usr/local/mysql/bin/mysql_config 上面两项参数是指定相关mysql库
–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
以上参数是指定PHP相关的一些模块（通用）。
3 安装可能会遇到的报错
3.1 configure: error: Cannot find OpenSSL's
3.2 查看 yum list |grep -i OpenSSL
# echo $?
1
# yum list |grep OpenSSL
这里注意大小写问题 -i
# yum list |grep -i OpenSSL
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/cbBFgil4jG.png?imageslim
yum install -y opensll-devel
# yum install -y openssl-devel
继续输入./configure 配置内容
configure: error: Please reinstall the BZip2 distribution
# yum install -y bzip2-devel
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/a5k×××gCI.png?imageslim
3.3 configure: error: jpeglib.h not found.
# yum install -y libjpeg-devel
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/La04C3EI2e.png?imageslim
继续输入./configure 配置内容
3.4 configure: error: png.h not found.
# yum install -y libpng-devel
3.5 configure: error: freetype-config not found
# yum install -y freetype-devel
3.6 configure: error: mcrypt.h not found. Please reinstall libmcrypt.
因为mcrypt.h这个库在epel-release这个扩展源里面
# yum install epel-release
3.7 configure: error: mcrypt.h not found. Please reinstall libmcrypt.
# yum install -y libmcrypt-devel
显示配置成功

4.make && make install 可以分两步查看有无错误

http://p0weeraap.bkt.clouddn.com/xavi2017/180302/hBEhma8GHG.png?imageslim
5.查看下生产的文件/usr/local/php,其中bin/下的是核心文件
# ls /usr/local/php
binetcincludelibphp
# ls /usr/local/php/bin/
pearpeardevpeclpharphar.pharphpphp-cgiphp-configphpize
6.du-sh来对比php文件和apache文件，libphp5.so文件是连接php和apache的重要文件
# du -sh /usr/local/php/bin/php
36M /usr/local/php/bin/php
# du -sh /usr/local/apache2.4/modules/libphp5.so
37M /usr/local/apache2.4/modules/libphp5.so
7.查看php加载的模块有哪些：/usr/local/php/bin/php -m，这些都是静态的模块
# /usr/local/php/bin/php -m

ctype
date
dom
ereg

7.1 php作为apache的模块存在的
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/d6AjEK5G55.png?imageslim
8. 查看apache的模块：/usr/local/apache2.4/bin/httpd -M
# /usr/local/apache2.4/bin/httpd -M
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::1d7a:ffe8:8235:a2a5. Set the 'ServerName' directive globally to suppress this message

8.1 php作为apache的一个模块存在的
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/3Fh3b3F3G1.png?imageslim
8.2 apache中关于php的模块文件
# ls -l /usr/local/apache2.4/modules/libphp5.so
-rwxr-xr-x 1 root root 37752768 3月 2 13:02 /usr/local/apache2.4/modules/libphp
9.打开apache的配置文件，输入/php5.so找到了增加的一行
# vim /usr/local/apache2.4/conf/httpd.conf
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/2B6KhiIDG1.png?imageslim
里面有很多被#注解的LaodMoudle，需要使用时可将注释去掉.
10. cp php.ini-production/usr/local/php/etc/php.ini
10.1查看php信息：/usr/local/php/bin/php -i |less
# /usr/local/php/bin/php -i |less
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/f1FlGc0mme.png?imageslim
10.2 查看ls /usr/local/php/etc没有php.ini文件
# ls /usr/local/php/etc
pear.conf
拷贝过来
# cp php.ini-production/usr/local/php/etc/php.ini
10.3 查看/usr/local/php/bin/php -i |less加载成功
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/GDAiJ7m276.png?imageslim
11.2 安装PHP7
1.下载安装包
# cd ..
# wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
2.解压：tar -jxvf php-7.1.6.tar.bz2
不加V的话不显示解压过程.
3.切换到php-7.1.6目录下
安装PHP-7
因为在安装PHP5的时候所有依赖的库文件以及安装完，所以此次PHP7可以直接安装。
#cd php-7.1.6
4.环境配置
#./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
注：次数与PHP-5的主要差异就是没有“--with-mysql”选项而是with-mysqli.

5.make编译和make install安装
http://p0weeraap.bkt.clouddn.com/xavi2017/180302/h8B3AIhCI3.png?imageslim
6./usr/local/apache2.4/modules/libphp7.so
# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
# du -sh !$
du -sh /usr/local/apache2.4/modules/libphp7.so
37M /usr/local/apache2.4/modules/libphp7.so
7.查看php7的模块：/usr/local/php7/bin/php -m
# /usr/local/php7/bin/php -m
bz2
Core
ctype
date
dom
exif
fileinfo
filter

pdo_sqlite
Phar

8. 查看Apache加载的PHP模块：php5_module (shared) php7_module (shared)
# /usr/local/apache2.4/bin/apachectl -M
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::1d7a:ffe8:8235:a2a5. Set the 'ServerName' directive globally to suppress this message
Loaded Modules:
core_module (static)
so_module (static)
.
.
.
php5_module (shared)
php7_module (shared)
9.此时Apache默认加载两个PHP模块，那么为了正常使用需要通过编辑Apache的配置文件来指定其工作时默认调用哪个PHP模块（注释掉其中一个调用参数即可）：
#vim /usr/local/apache2.4/conf/httpd.conf
