A+ A-memcahced是一个高性能的分布式内存对象缓存系统, 用于动态web应用以减轻数据库负载. 它通过在内存中缓存数据和对象来减少读取数据库的次数. 从而提高动态数据库驱动网站的访问速度
解决session问题,一般有三种解决方案:
1. session保持
2. session复制
3. session共享
1. 创建memcache所需目录结构
[[email protected]_210 ~]# cd /data/etc/salt/ [[email protected]_210 salt]# mkdir memcache/libevent/files -p [[email protected]_210 salt]# mkdir memcache/memcached/files -p [[email protected]_210 salt]# mkdir memcache/php-memcache/files -p [[email protected]_210 salt]# mkdir memcache/user [[email protected]_210 salt]# tree memcache/ memcache/ |-- init.sls |-- libevent | |-- files | | `-- libevent-2.0.22-stable.tar.gz | `-- install.sls |-- memcached | |-- files | | `-- memcached-1.4.31.tar.gz | |-- install.sls | `-- service.sls |-- php-memcache | |-- files | | `-- memcache-2.2.7.tgz | `-- install.sls `-- user `-- create_90root.sls [[email protected]_210 salt]# # cd memcache/ [[email protected]_210 memcache]# cat init.sls include: - memcache.memcached.service - memcache.php-memcache.install [[email protected]_210 memcache]# cat ../top.sls base: '*': - memcache.init
2. 创建memcached监听用户
[[email protected]_210 ~]# cd /data/etc/salt/memcache/user/ [[email protected]_210 user]# cat create_90root.sls 90root-user-group: group.present: - name: 90root - gid: 1000 user.present: - name: 90root ->username - fullname: 90root ->用户全名 - shell: /sbin/nologin ->shell环境 - uid: 1000 ->user uid - gid: 1000 ->user gid - createhome: True ->不创建用户家目录
3. Libevent安装及配置
[[email protected]_210 ~]# cd /data/etc/salt/memcache/libevent/files [[email protected]_210 files]# wget https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz [[email protected]_210 files]# cd /data/etc/salt/memcache/libevent/ [[email protected]_210 libevent]# vim install.sls libevent-source: file.managed: - name: /usr/local/src/libevent-2.0.22-stable.tar.gz - unless: test -e /usr/local/src/libevent-2.0.22-stable.tar.gz - source: salt://memcache/libevent/files/libevent-2.0.22-stable.tar.gz - user: root - group: root - mode: 644 libevent-extrace: cmd.run: - cwd: /usr/local/src - names: - tar zxf libevent-2.0.22-stable.tar.gz && chown -R root:root libevent-2.0.22-stable - unless: test -d /usr/local/src/libevent-2.0.22-stable - require: - file: libevent-source libevent-compile: cmd.run: - name: cd /usr/local/src/libevent-2.0.22-stable && ./configure --prefix=/usr/local/libevent && make && make install - unless: test -d /usr/local/libevent - require: - cmd: libevent-extrace
4. Memcached配置
[[email protected]_210 ~]# cd /data/etc/salt/memcache/memcached/files/ [[email protected]_210 files]# wget http://www.memcached.org/files/memcached-1.4.31.tar.gz [[email protected]_210 files]# vim ../install.sls include: - memcache.libevent.install memcached-source: file.managed: - name: /usr/local/src/memcached-1.4.31.tar.gz - unless: test -e /usr/local/src/memcached-1.4.31.tar.gz - source: salt://memcache/memcached/files/memcached-1.4.31.tar.gz - user: root - group: root - mode: 644 memcached-extrace: cmd.run: - cwd: /usr/local/src - names: - tar zxf memcached-1.4.31.tar.gz && chown -R root:root memcached-1.4.31 - unless: test -d /usr/local/src/memcached-1.4.31 - require: - file: memcached-source memcached-install: cmd.run: - name: cd /usr/local/src/memcached-1.4.31 && ./configure --prefix=/usr/local/memcached --enable-64bit --with-libevent=/usr/local/libevent && make && make install - unless: test -d /usr/local/memcached - require: - cmd: memcached-extrace
5. 启动Memcached服务
[[email protected]_210 ~]# cd /data/etc/salt/memcache/memcached/ [[email protected]_210 memcached]# vim service.sls include: - memcache.memcached.install - memcache.user.create_90root - memcache.libevent.install memcached-service: cmd.run: - name: /usr/local/memcached/bin/memcached -d -m 128 -p 11211 -c 8096 -u 90root - unless: netstat -anpt | grep 11211 - require: - cmd: memcached-install - user: 90root-user-group
6. 安装php memcache扩展
[[email protected]_210 ~]# cd /data/etc/salt/memcache/php-memcache/files [[email protected]_210 files]# wget http://pecl.php.net/get/memcache-2.2.7.tgz [[email protected]_210 php-memcache]# cat install.sls memcache_plugin: file.managed: - name: /usr/local/src/memcache-2.2.7.tgz - source: salt://memcache/php-memcache/files/memcache-2.2.7.tgz - user: root - group: root memcache_extrace: cmd.run: - cwd: /usr/local/src - names: - tar zxf memcache-2.2.7.tgz && chown -R root:root memcache-2.2.7 - unless: - file: memcache_plugin memcache_compile: cmd.run: - names: - cd /usr/local/src/memcache-2.2.7 && /usr/local/php-fpm/bin/phpize && ./configure --enable-memcache --with-php-config=/usr/local/php-fpm/bin/php-config && make && make install - unless: test -f /usr/local/php-fpm/lib/php/extensions/*/memcache.so - require: - cmd: memcache_extrace /usr/local/php-fpm/etc/php.ini: file.append: -> 往上面文件追加memcache.so - text: - extension=memcache.so [[email protected]_210 php-memcache]# ll files/ total 36 -rw-r--r-- 1 root root 36459 Mar 30 2015 memcache-2.2.7.tgz
7. 先测试，后安装memcached
[[email protected]_210 salt]# salt 'docker_211' state.highstate test=True
[[email protected]_210 salt]# salt 'docker_211' state.highstate [[email protected]_210 memcached]# salt 'docker_211' cmd.run 'netstat -anpt|grep 11211' docker_211: tcp 0 0 0.0.0.0:11211 0.0.0.0:* LISTEN 15351/memcached tcp 0 0 :::11211 :::* LISTEN 15351/memcached
