一、安裝PHP7
1.yum安裝編譯php需要的包
yum -y install libxml2 libxml2-devel curl-devel libpng-devel freetype-devel libmcrypt-devel libjpeg-devel
2.創建php用戶組和用戶
groupadd php
useradd -r -g php -s /sbin/nologin -M php
3.下載php源碼包，將源碼包放到/usr/local/src/目錄下
下載頁面：http://www.php.net/downloads.php
這裏用的是 php-7.0.13.tar.gz
下載地址：http://cn2.php.net/distributions/php-7.0.13.tar.gz
4.進入src/目錄
cd /usr/local/src/
5.解壓源碼包
tar -zxf php-7.0.13.tar.gz
6.進入php源碼目錄，編譯安裝（配置參數：http://php.net/manual/zh/configure.about.php）
cd php-7.0.13/
./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--with-mysql-sock=/var/lib/mysql/mysql.sock \
--enable-fpm \
--enable-ftp \
--enable-xml \
--enable-zip \
--enable-soap \
--enable-pcntl \
--enable-shmop \
--enable-bcmath \
--enable-shared \
--enable-mysqlnd \
--enable-opcache \
--enable-session \
--enable-sockets \
--enable-sysvsem \
--enable-mbregex \
--enable-mbstring \
--enable-gd-native-ttf \
--enable-inline-optimization \
--with-gd \
--with-curl \
--with-mhash \
--with-iconv \
--with-xmlrpc \
--with-gettext \
--with-jpeg-dir \
--with-freetype-dir \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-openssl \
--without-gdbm \
--without-pear \
--disable-debug \
--disable-rpath \
--disable-fileinfo
make && make install
7.源碼安裝包有兩個php.ini-xxx文件，一個是產品模式，一個是開發模式。根據需求選擇一個改名爲php.ini放到php/etc/目錄下
cp /usr/local/src/php-7.0.13/php.ini-development /usr/local/php/etc/php.ini
8.修改php目錄權限
chown -R php:php
9.將php命令加入環境變量，修改profile文件
vim /etc/profile
10.修改爲下面內容，保存退出c
PATH=/usr/local/mysql/bin:/usr/local/php/bin:$PATH
11.使/etc/profile裏的配置立即生效
source /etc/profile
二、配置Apache支持PHP7
1.修改apache配置文件httpd.conf
vim /usr/local/apache/conf/httpd.conf
2.找到下面位置，加入紅色標記部分，保存退出
DirectoryIndex index.html index.php
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
Addtype application/x-httpd-php .php .phtml
3.重啓apache
service httpd restart
4.在apache的web目錄下添加php文件，如/usr/local/apache/htdocs/phpinfo.php
<?php
phpinfo();
訪問URL，如：http://192.168.8.9:8088/phpinfo.php
頁面顯示正常，則配置成功
三、配置Nginx支持PHP7
1.配置php-fpm
php-fpm.conf是 php-fpm 進程服務的配置文件
www.conf這是 php-fpm 進程服務的擴展配置文件
cd /usr/local/php/etc
mv php-fpm.conf.default php-fpm.conf
mv php-fpm.d/www.conf.default php-fpm.d/www.conf
2.將php-fpm服務腳本加入到init.d/目錄
cp /usr/local/src/php-7.0.13/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
3.爲php-fpm添加可執行權限
chmod +x /etc/init.d/php-fpm
4.將php-fpm加入系統服務
chkconfig --add php-fpm
5.修改服務的默認啓動等級
chkconfig php-fpm on
6.啓動php-fpm
service php-fpm start
7.修改nginx配置文件nginx.conf
vim /usr/local/nginx/conf/nginx.conf
8.把前面的#註釋符號去掉，把/script改爲$document_root，保存退出
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
9.重啓nginx
service nginx restart
10.在nginx的web目錄下添加php文件，如/usr/local/nginx/html/phpinfo.php
<?php
phpinfo();
訪問URL，如：http://192.168.8.9/phpinfo.php
頁面顯示正常，則配置成功
四、測試PHP7操作MySQL
在web目錄下添加php文件，如/usr/local/apache/htdocs/mysql.php 或 /usr/local/nginx/html/mysql.php
<?php
$host = 'localhost';
$user = 'root';
$pass = 'root123';
$database = 'mysql';
$sql = 'SELECT * FROM user LIMIT 1';
/*連接MySQLi*/
try {
$con = mysqli_connect($host, $user, $pass, $database);
$result = mysqli_query($con, $sql);
//獲取數據
$data = mysqli_fetch_all($result, MYSQLI_ASSOC);
print_r($data);
//釋放結果集
mysqli_free_result($result);
mysqli_close($con);
} catch (Exception $e) {
print "MySQLi Error: " . $e->getMessage() . "<br/>";
}
echo "<hr>";
/*連接PDO*/
try {
$dbh = new PDO("mysql:host=$host;dbname=$database", $user, $pass);
foreach ($dbh->query($sql) as $row) {
print_r($row);
}
$dbh = null;
} catch (PDOException $e) {
print "PDO Error: " . $e->getMessage() . "<br/>";
}
訪問URL，如：http://192.168.8.9/mysql.php
