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

[root@xavi ~]#  cd /usr/local/src/
[root@xavi src]# wget http://cn2.php.net/distributions/php-5.6.30.tar
[root@xavi src]# 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==

[root@xavi ~]#  cd /usr/local/src/
[root@xavi src]# wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
[root@xavi src]#tar zxvf php-5.6.30.tar.gz

2 配置安装

[root@xavi src]# cd php-5.6.30/
[root@xavi 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 <evp.h>

3.2 查看 yum list |grep -i OpenSSL

[root@xavi php-5.6.30]# echo $?
1
[root@xavi php-5.6.30]# yum list |grep OpenSSL

这里注意大小写问题 -i

[root@xavi php-5.6.30]# yum list |grep -i OpenSSL

yum install -y opensll-devel

[root@xavi php-5.6.30]# yum install -y openssl-devel

继续输入./configure 配置内容

configure: error: Please reinstall the BZip2 distribution
[root@xavi php-5.6.30]# yum install -y bzip2-devel

3.3 configure: error: jpeglib.h not found.

[root@xavi php-5.6.30]# yum install -y libjpeg-devel

继续输入./configure 配置内容

3.4 configure: error: png.h not found.

[root@xavi php-5.6.30]# yum install -y libpng-devel

3.5 configure: error: freetype-config not found

[root@xavi php-5.6.30]# 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

[root@xavi php-5.6.30]# yum install epel-release

3.7 configure: error: mcrypt.h not found. Please reinstall libmcrypt.

[root@xavi php-5.6.30]# 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

5.查看下生产的文件/usr/local/php,其中bin/下的是核心文件

[root@xavi php-5.6.30]# ls /usr/local/php
bin  etc  include  lib  php
[root@xavi php-5.6.30]# ls /usr/local/php/bin/
pear  peardev  pecl  phar  phar.phar  php  php-cgi  php-config  phpize

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

[root@xavi php-5.6.30]# du -sh /usr/local/php/bin/php
36M	/usr/local/php/bin/php
[root@xavi php-5.6.30]# 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

[root@xavi php-5.6.30]# /usr/local/php/bin/php -m
[PHP Modules]

7.1 php作为apache的模块存在的

8. 查看apache的模块：/usr/local/apache2.4/bin/httpd -M

[root@xavi php-5.6.30]# /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

8.2 apache中关于php的模块文件

[root@xavi php-5.6.30]# 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

[root@xavi php-5.6.30]# vim /usr/local/apache2.4/conf/httpd.conf

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

[root@xavi php-5.6.30]# /usr/local/php/bin/php -i |less

10.2 查看ls /usr/local/php/etc没有php.ini文件

[root@xavi php-5.6.30]# ls /usr/local/php/etc
pear.conf

拷贝过来

[root@xavi php-5.6.30]# 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

11.2 安装PHP7

1.下载安装包

[root@xavi php-5.6.30]# cd ..
[root@xavi src]# 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。

[root@xavi src]#  cd php-7.1.6

4.环境配置

[root@xavi 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

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

6./usr/local/apache2.4/modules/libphp7.so

[root@xavi php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
[root@xavi php-7.1.6]# 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

[root@xavi php-7.1.6]# /usr/local/php7/bin/php -m
[PHP Modules]
bz2
Core
ctype

posix

[Zend Modules]

8. 查看Apache加载的PHP模块：php5_module (shared) php7_module (shared)

[root@xavi php-7.1.6]# /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）：

[root@xavi php-7.1.6]#  vim /usr/local/apache2.4/conf/httpd.conf
