centos系统中php7安装memcached 扩展

#编译安装php-7.1.16

#wget http://cn2.php.net/distributions/php-7.1.16.tar.gz
#tar -zxvf php-7.1.16.tar.gz
#cd php-7.1.16
#./configure --prefix=/usr/local/php-7.1.16 --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-iconv --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pdo-odbc=unixODBC,/usr/ --with-pdo-dblib=/usr/local/freetds --with-pear --with-png-dir --with-xmlrpc --with-xsl --with-zlib --with-jpeg-dir=/usr --with-png-dir=/usr --with-mcrypt --with-mssql=/usr/local/freetds --enable-ftp --enable-exif --enable-calendar --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
#make && make install

php7 安装memcached扩展

1. 首先安装memcache的客户端库 libmemcached。

php版本不高于5.6可以安装

1	`wget https://launchpad.net/libmemcached/1.0/1.0.17/+download/libmemcached-1.0.17.tar.gz`

php7版本的1.0.17版本的libmemcache库安转不了会报错只能装下面的1.0.18版本的

wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz
tar -zxvf libmemcached-1.0.18.tar.gz
cd libmemcached-1.0.18
./configure
make && make install

2.安装 php7 memcache扩展

git clone https://github.com/php-memcached-dev/php-memcached 
git checkout -b php7 
cd php_memcache
/usr/local/php/bin/phpize 
./configure --with-php-config=/usr/local/php/bin/php-config 
make && make install

修改php.ini的配置

/usr/local/php7.1/lib/php.ini
加上：extension_dir="/usr/local/php7.1/lib/php/extensions/no-debug-non-zts-20160303/"(每个人的路径可能不一样)
extension = "memcached.so

重启php-fpm

php7安装redis拓展

phpredis下载地址https://github.com/phpredis/phpredis

解压并进入源码包
unzip phpredis-develop.zip
cd phpredis-develop
生成configure配置文件:/usr/local/php-7.1/bin/phpize
编译安装:
./configure --with-php-config=/usr/local/php-7.1/bin/php-config
make && make install

修改php.ini配置

/usr/local/php7.1/lib/php.ini
加上：extension_dir="/usr/local/php7.1/lib/php/extensions/no-debug-non-zts-20160303/"(每个人的路径可能不一样)
extension=redis.so
重启php

检查:

1 2	`[root@test etc]# /usr/local/php-7.1/bin/php -m\|grep redis` `redis`

测试链接mssql

<?php
try {
$hostname='111.111.111.111';//注意,这里和上面不同,要直接用IP地址或主机名
$port=1433;//端口
$dbname="db_1";//库名
$username="dbname";//用户
$pw="dbpass";//密码
$dbh= new PDO("dblib:host=$hostname:$port;dbname=$dbname;charset=UTF-8","$username","$pw");
} catch (PDOException $e) {
echo"Failed to get DB handle: ".$e->getMessage() ."n";
exit;
}
echo'connent MSSQL succeed';
$stmt=$dbh->prepare("select firstname,lastname from table");
$stmt->execute();
while ($row=$stmt->fetch()) {
print_r($row);
}
unset($dbh); unset($stmt);
?>

测试连接memcached

<?php
$memcache = new Memcached;
$memcache->addServer('192.168.1.20',11211) or dir ("Could not connect");
$memcache->set('key','Hello world!');
$get_value = $memcache->get('key');
echo $get_value;
?>
