linux的PHP5和PHP7安装

arongsoft

PHP5安装

• PHP官网www.php.net
  
• 当前主流版本为5.6/7.1
  
• 进入存储源码包的目录：
  [root@gary-tao ~]# cd /usr/local/src
  
• 下载php的源码包：
  

　　地址：wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
　　5.解压压缩包：

[root@gary-tao src]# tar -zxvf php-5.6.30.tar.gz
　　6.进入安装目录：

[root@gary-tao src]# cd php-5.6.30
[root@gary-tao php-5.6.30]#
　　7.安装php：

[root@gary-tao 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  //安装PHP
[root@gary-tao php-5.6.30]# echo $?  //安装完成没有错误用这个检查
0

　　解释说明个别参数：

--prefix：指定安装目录。
--with-apxs2：Apache的工具，指定工具的地址，可以帮我们自动配置一些模块,不用人工干涉。
--with-config-file-path：指定配置文件的路径。
--with-mysql：指定mysql路径。
　　安装报错：

• 缺少libxml2这个库，安装命令：yum install -y libxml2-devel
  

• 缺少openssl库，安装命令：yum install -y openssl-devel
  

• 缺少bzip2包，安装命令：yum install -y bzip2-devel
  

• 缺少jpeglid包,安装命令：yum install -y libjpeg-devel
  

• 缺少libpng包，安装命令：yum install -y libpng-devel
  

• 缺少freetype包，安装命令:yum install -y freetype-devel
  

• 缺少libmcrypt包，安装命令：yum install -y libmcrypt-devel，如果你没有安装epel-release这个扩展源，就需要先安装这个扩展源，因为libmcrypt是在这个扩展源里面，安装扩展源命令：yum install -y epel-release
  

　　8.编译安装

[root@gary-tao php-5.6.30]# make
[root@gary-tao php-5.6.30]# make install
[root@gary-tao php-5.6.30]# echo $?
0
　　备注：Apache和php结合的通过图中的libphp5.so模块

　　9.查看php加载的模块（都是静态的）：

[root@gary-tao php-5.6.30]# /usr/local/php/bin/php -m
[PHP Modules]
bz2
Core
ctype
date
dom
ereg
exif
fileinfo
filter
gd
hash
iconv
json
libxml
mbstring
mcrypt
mysql
mysqli
openssl
pcre
PDO
pdo_mysql
pdo_sqlite
Phar
posix
Reflection
session
SimpleXML
soap
sockets
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter
zlib
[Zend Modules]
　　10.PHP是做为apache的模块存在，查看模块：

[root@gary-tao 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 218.93.250.18. Set the 'ServerName' directive globally to suppress this message

[root@gary-tao php-5.6.30]# ls -l /usr/local/apache2.4/modules/libphp5.so   //模块文件
-rwxr-xr-x 1 root root 37752872 12月 18 17:09 /usr/local/apache2.4/modules/libphp5.so

　　解释说明：
php5_module (shared)：这个说明PHP是作为httpd扩展模块的形式存在的,那如果apache要想执行php的脚本，它就需要依赖借助于这个模块文件，如果把这个.so文件删除，那apache就不支持php了，这个模块非常重要。
　　11.这个httpd的配置文件里就多了一行php模块，被注释掉的就是没有用的模块，如果想用，把#号去掉就可以了，随用随取：

[root@gary-tao php-5.6.30]# vim /usr/local/apache2.4/conf/httpd.conf  //这是apache的配置文件

　　12.把php的参考配置文件复制到php的配置文件目录下：
　　示例如下：

[root@gary-tao php-5.6.30]# /usr/local/php/bin/php -i |less  //查看php的一些配置信息，包括编译参数。
phpinfo()

PHP7安装

• 进入源码包的目录：
  [root@gary-tao ~]# cd /usr/local/src/
  　　2.下载源码包：
  
  

　　地址：wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
　　3.解压压缩包：

[root@gary-tao src]#  tar jxvf php-7.1.6.tar.bz2

　　备注：如果没有安装bzip2压缩工具，请安装：yum install -y bzip2
　　4.进入目录：

[root@gary-tao src]# cd php-7.1.6
[root@gary-tao php-7.1.6]#
　　5.安装php7：

[root@gary-tao 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
　　6.编译安装：

[root@gary-tao php-7.1.6]# make
[root@gary-tao php-7.1.6]# make install
　　7.php7模块路径：

[root@gary-tao php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
　　8.查看php7加载的模块（静态）：

[root@gary-tao php-7.1.6]# /usr/local/php7/bin/php -m
[PHP Modules]
bz2
Core
ctype
date
dom
exif
fileinfo

pdo_sqlite
Phar
posix
Reflection
session
SimpleXML
soap
sockets
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter

[Zend Modules]

　　9.查看apache加载了几个php,通过修改配置文件来指定使用php5还是php7模块，不要的就注释掉：
　　示例如下：

[root@gary-tao 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 218.93.250.18. Set the 'ServerName' directive globally to suppress this message

authz_groupfile_module (shared)
authz_user_module (shared)
authz_core_module (shared)
access_compat_module (shared)

php5_module (shared)
php7_module (shared)
[root@gary-tao php-7.1.6]# vim /usr/local/apache2.4/conf/httpd.conf

　　10.把php7的参考配置文件复制到php7的配置文件目录下：

[root@gary-tao php-7.1.6]# cp php.ini-production  /usr/local/php7/etc/php.ini
