Linux下安装PHP7.1并做关联APACHE处理

1.复制php压缩包到/usr/local/src

2.解压

tar -zxvf php-7.1.2.tar.gz

3.编译安装(请先安装apache和mysql)

./configure --prefix=/usr/local/php7 
 --with-apxs2=/usr/local/apache2/bin/apxs 
 --with-curl 
 --with-freetype-dir 
 --with-gd 
 --with-gettext 
 --with-iconv-dir 
 --with-kerberos 
 --with-libdir=lib64 
 --with-libxml-dir 
 --with-mysqli 
 --with-openssl 
 --with-pcre-regex 
 --with-pdo-mysql 
 --with-pdo-sqlite 
 --with-pear 
 --with-png-dir 
 --with-xmlrpc 
 --with-xsl 
 --with-zlib 
 --enable-fpm 
 --enable-bcmath 
 --enable-libxml 
 --enable-inline-optimization 
 --enable-gd-native-ttf 
 --enable-mbregex 
 --enable-mbstring 
 --enable-opcache 
 --enable-pcntl 
 --enable-shmop 
 --enable-soap 
 --enable-sockets 
 --enable-sysvsem 
 --enable-xml 
 --enable-zip 
 --enable-maintainer-zts

核心就是配置关联

--with-apxs2=/usr/local/apache2/bin/apxs

4.如果有编译错误

yum安装

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel  pcre-devel openssl openssl-devel curl-devel libxslt-devel

5.make && make install

make && make install

如果有残留make clean一下

make clean
make
make install

6.apache与php的关联

PHP安装成功后会在apache的modules目录下生成一个libphp.so动态库文件，在apache的配置文件httpd.conf里自动增加一行。

vi /etc/httpd/httpd.conf

LoadModule php7_module        modules/libphp7.so  

在Apache的配置文件httpd.conf的<IfModule mime_module></IfModule>块里增加一行

AddType application/x-httpd-php .php  

配置index.php为默认执行的文件

<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

7.重启apache

可能会出现 Could not reliably determine the server's fully qualified domain name
解决方案：

用记事本打开 httpd.conf

将里面的 #ServerName localhost:80 注释去掉即可。

再执行 httpd

然后可以通过浏览器访问 http://localhost:80 ，如果页面显示 “It works！” ，即表示apache已安装并启动成功。

8.查看phpinfo()

这些都是php支持mysql的模块，不需要跟具体的mysql关联。

9.写代码查看sql连接

$conn=mysqli_connect("127.0.0.1","root","123456");
if($conn){
	echo"ok";
}else{
	echo"error";    
}

附上yum一些指令，避免yum的mysql的干扰！

查询yum的安装包

    yum list installed 

查看具体的包信息

    yum info mysql

移除mysql

    yum remove mysql-libs.x86_64

不会影响到自己编译的mysql
