memcache 安装 （windows和linux）

摘要：环境下安装下载安装包解压到盘任意位置以管理员身份运行，否则安装失败执行命令没有报错说明我们已经安装成功下载我的是的版本所以下载位版本将扩展放入扩展文件夹中在中添加然后重启注意文件夹中的是用于浏览器访问文件夹中的是适用于命令行运行脚本测试代码

下载 memcache 安装包 ：http://pan.baidu.com/s/1pLcjTzl

解压到d盘任意位置 , cmd(以管理员身份运行，否则安装失败) 执行命令

没有报错说明我们已经安装成功

下载 php_memcache.dll : https://pecl.php.net/package/memcache/3.0.8/windows

我的是5.6的版本 所以下载 64位 TS版本

将dll扩展放入php扩展文件夹中

在php.ini 中添加 extension=php_memcache.dll

然后重启wampserver
注意：apache文件夹中的php.ini 是用于浏览器访问 php文件夹中的php.ini 是适用于命令行运行php脚本

php测试代码 (我的是命令行测试)

安装环境说明：

操作系统：Centos 6.5 -64bit
安装路径：/usr/local/memcached

yum install libevent libevent-devel

[root@localhost home]# wget http://memcached.org/files/memcached-1.4.25.tar.gz

tar zxvf memcached-1.4.25.tar.gz

打开文件夹 指定安装路径 并编译

cd memcached-1.4.25

./configure --prefix=/usr/local/memcached

make && make install

下载php memcache 扩展 tgz包

[root@localhost home]# wget https://pecl.php.net/get/memcache-3.0.8.tgz
[root@localhost home]# tar zxf memcache-3.0.8.tgz
[root@localhost home]# cd memcache-3.0.8
[root@localhost memcache-3.0.8]# /usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
# 安装成功后会输出这个地址，这是php扩展模块文件夹 /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

#php.ini 中的 extension_dir =” ./”  
#修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/” 
(若已经修改过请忽略)

#添加 
extension=memcache.so

#重启 php-fpm 
/etc/init.d/php-fpm restart

下载libevent tgz包 并安装
官网：http://libevent.org/

[root@localhost home]# tar zxf libevent-2.0.21-stable.tar.gz
[root@localhost home]# cd libevent-2.0.21-stable
[root@localhost home]# ./configure --prefix=/usr/local/libevent/
[root@localhost libevent-2.0.21-stable]# make && make install

重新编译安装memcached服务，并配置libevent

[root@localhost home]# cd memcached-1.4.25
[root@localhost memcached-1.4.25]# ./configure --prefix=/usr/local/memcache/ --with-libevent=/usr/local/libevent/
[root@localhost memcached-1.4.25]# make && make install

下载 libmemcached tgz包 并编译安装

安装SASL相关环境
yum install cyrus-sasl-plain cyrus-sasl  cyrus-sasl-devel  cyrus-sasl-lib 

官网：http://libmemcached.org/libMemcached.html
[root@localhost home]# wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz
[root@localhost home]# tar zxf libmemcached-1.0.18.tar.gz
[root@localhost home]# cd libmemcached-1.0.18
[root@localhost libmemcached-1.0.18]# ./configure --prefix=/usr/local/libmemcached  --with-memcached --enable-sasl
[root@localhost libmemcached-1.0.18] make
[root@localhost libmemcached-1.0.18] make install

下载php memcached 扩展 tgz包

[root@localhost home]# wget https://pecl.php.net/get/memcached-2.2.0.tgz
[root@localhost home]# tar zxf memcached-2.2.0.tgz
[root@localhost home]# cd memcached-2.2.0
[root@localhost memcached-2.2.0]# /usr/local/php/bin/phpize

    ./configure --with-php-config=/usr/local/php/bin/php-config 
    --with-libmemcached-dir=/usr/local/libmemcached  --enable-memcached-sasl（注意这个参数）

如果提示下面错误信息 说明我们要安装 libsasl2-dev    

yum直接搜索是没有对应的package的 我们用笨方法
[root@localhost home]# yum search sasl |  grep  dev
[root@localhost home]# yum install cyrus-sasl-devel 

继续编译

./configure --with-php-config=/usr/local/php/bin/php-config 
--with-libmemcached-dir=/usr/local/libmemcached  --enable-memcached-sasl（注意这个参数）
 make 
 make install

# 安装成功后会输出这个地址，这是php扩展模块文件夹
/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

#php.ini 中的 extension_dir =” ./”  
#修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/” 
(若已经修改过请忽略)

#添加 
extension=memcached.so

#重启 php-fpm 
/etc/init.d/php-fpm restart

[root@localhost init.d]# touch memcached
[root@localhost init.d]# chmod 777 memcached

复制粘贴以下内容于 redis文件 保存退出

配置开启自启动

chkconfig --add memcached

增加开启启动设置启动级别

chkconfig --level 2345 memcached on

测试启动，停止，重启memcached

# 服务启动，停止service memcached start service memcached stop
# init.d目录启动，停止/etc/init.d/memcached start/etc/init.d/memcached stop

# 打开防火墙规则vim /etc/sysconfig/iptables

# 增加内容 -A INPUT -p tcp -m tcp --dport 11211 -j ACCEPT   




# 重启火墙规则立即生效service iptables restart
