Memcached源码安装配置

Memcached源码安装配置

官方网站:
memcached - a distributed memory object caching system
Free & open source, high-performance, distributed memory object caching system


环境:
CentOS 7.1/6.5
memcached-1.4.25


一.安装编译依赖库
yum -y install gcc gcc-c++ unzip gzip bzip2 libevent-devel cyrus-sasl-devel systemtap-sdt-devel


二.编译安装
tar -xvf memcached-1.4.25.tar.gz -C /usr/local/src
cd /usr/local/src/memcached-1.4.25
./configure --prefix=/opt/memcached \
--enable-sasl \
--enable-sasl-pwdb \
--enable-dtrace \
--enable-64bit
make -j4 && make -j4 install

cp -a /opt/memcached/share/man/* /usr/share/man
cp -a /usr/local/src/memcached-1.4.25/scripts /opt/memcached/


三.init sysv脚本
useradd -r -s /sbin/nologin memcached
mkdir -p /var/run/memcached/

cp -f /usr/local/src/memcached-1.4.25/scripts/memcached.sysv /etc/init.d/memcached

sed -i 's#daemon memcached#daemon /opt/memcached/bin/memcached#' /etc/init.d/memcached

sed -i "/^USER=/c USER=memcached" /etc/init.d/memcached

sed -i "/^CACHESIZE=/c CACHESIZE=2048" /etc/init.d/memcached


chmod +x /etc/init.d/memcached
chkconfig memcached on


四.配置并启动
init脚本启动
service memcached start
Memcached源码安装配置

命令行启动
/opt/memcached/bin/memcached -d -u memcached -m 2048 -t 4 -p 11211 -P /tmp/memcached.pid
命令行停止
kill -9 $(cat /tmp/memcached.pid)或killall memcached
提示:命令行更为灵活，memcached -h可以查看所有可定制选项参数

GUI管理工具

php扩展(memcached & memcache)

http://libmemcached.org/libMemcached.html

http://php.net/manual/zh/book.memcached.php

http://pecl.php.net/package/memcached

注意:php的memcached扩展，功能和特性比memcache扩展都要优秀

1.安装libmemcached

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz

tar -xvf libmemcached-1.0.18.tar.gz -C /usr/local/src/

cd /usr/local/src/libmemcached-1.0.18

./configure && make && make install

2.安装php memcached扩展库

wget http://pecl.php.net/get/memcached-2.2.0.tgz

tar -xvf memcached-2.2.0.tgz -C /usr/local/src/

cd /usr/local/src/memcached-2.2.0

phpize

./configure --enable-memcached-json && make -j4 && make -j4 install

3.php.ini加载memcached.so

echo extension=memcached.so >>/usr/local/php/etc/php.ini

service php-fpm restart

memcached

memcached support enabled
Version  2.2.0 
libmemcached version  1.0.18 
SASL support  yes 
Session support  yes 
igbinary support  no 
json support  yes 
msgpack support  no


但有些php GUI是基于php memcache的扩展库，所以这里也一并安装

http://php.net/manual/zh/memcache.installation.php

http://pecl.php.net/package/memcache

wget http://pecl.php.net/get/memcache-2.2.7.tgz

tar -xvf memcache-2.2.7.tgz /usr/local/src/

cd /usr/local/src/memcache-2.2.7

phpize

./configure && make -j4 && make -j4 install

echo extension=memcache.so >>/usr/local/php/etc/php.ini

 

 

service php-fpm restart

root@jlive:memcache-2.2.7#ls /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

ldap.so*  memcached.so*  memcache.so*  opcache.a*  opcache.so*

memcache

memcache support enabled
Active persistent connections  0

php memcache GUI工具--MemAdmin

基于 PHP5 & JQuery 的 Memcached 管理监控工具，界面非常清爽

wget http://www.junopen.com/memadmin/memadmin-1.0.12.tar.gz

tar -xvf memadmin-1.0.12.tar.gz -C /usr/local/nginx/html

Memcached源码安装配置
默认用户名和密码为admin/admin, memadmin/config.php可以修改
