cd /opt rm -rf memcached-1.2.0.tar.gz wget http://192.168.0.97/download/linux/cache/memcached-1.2.0.tar.gz rm -rf memcached-1.2.0 tar -zxf memcached-1.2.0.tar.gz cd /opt/memcached-1.2.0 ./configure –with-libevent= make make install
2、安装 memcache 客户端
cd /opt rm -rf memcache-2.2.5.tgz wget http://192.168.0.97/download/linux/cache/memcache-2.2.5.tgz rm -rf memcache-2.2.5 tar -zxf memcache-2.2.5.tgz cd /opt/memcache-2.2.5 /usr/local/php/bin/phpize ./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir make make install# 修改php.ini
- – - – - vi /etc/php.ini /extension_dir = iextension=memcache.so extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/” # - – - – - -
# 重启 apache php生效 /usr/local/apache2/bin/apachectl restart
3、一般的维护 开启 关闭 查看状态
开启memcache 服务端 /usr/local/bin/memcached -d -m 128 -u root -l 192.168.0.97 -c 256 -P /tmp/memcached.pid关闭memcache 服务端 kill `cat /tmp/memcached.pid`
写成脚本 vi /etc/init.d/memcache_start.sh i/usr/local/bin/memcached -d -m 128 -u root -l 192.168.0.97 -c 256 -P /tmp/memcached.pid chmod a+x /etc/init.d/memcache_start.sh
vi /etc/init.d/memcache_stop.sh ikill `cat /tmp/memcached.pid` chmod a+x /etc/init.d/memcache_start.sh
查看memcache状态 telnet 192.168.0.98 11211 输入stats查询状态 stats STAT pid 8601 STAT uptime 696 STAT time 1245832689 STAT version 1.2.0 STAT pointer_size 64 STAT rusage_user 0.007998 STAT rusage_system 0.030995 STAT curr_items 1 STAT total_items 1 STAT bytes 76 STAT curr_connections 2 STAT total_connections 4 STAT connection_structures 3 STAT cmd_get 1 STAT cmd_set 1 STAT get_hits 1 STAT get_misses 0 STAT bytes_read 97 STAT bytes_written 620 STAT limit_maxbytes 134217728 END
-d选项是启动一个守护进程， -m是分配给Memcache使用的内存数量，单位是MB，我这里是10MB， -u是运行Memcache的用户，我这里是root， -l是监听的服务器IP地址，如果有多个地址的话，我这里指定了服务器的IP地址192.168.22.200， -p是设置Memcache监听的端口，我这里设置了12000，最好是1024以上的端口， -c选项是最大运行的并发连接数，默认是1024，我这里设置了256，按照你服务器的负载量来设定， -P是设置保存Memcache的pid文件，我这里是保存在 /tmp/memcached.pid，
4、在客户端使用php测试
查看源码 打印 ? 1<?php 2$mem=new Memcache; 3$mem->connect(“192.168.0.97″,11211); 4$mem->set(‘key’,'This is a test!’, 0, 60); 5$val=$mem->get(‘key’); 6echo $val; 7?>
