本人在本着共享的原则在文中略作修改.
一.软件下载
wget http://memcached.googlecode.com/files/memcached-1.4.13.tar.gz
wget http://memagent.googlecode.com/files/magent-0.6.tar.gz
wget http://monkey.org/~provos/libevent-1.4.9-stable.tar.gz
二。安装libevent-1.4.9-stable.tar.gz
tar zxvf libevent-2.0.13-stable.tar.gz
cd libevent-2.0.13-stable
./configure --with-libevent=/usr
make
make install
三。安装memcacd
tar zxvf memcached-1.4.13.tar.gz
cd memcached-1.4.13
./configure --with-libevent=/usr
make
make install
四。安装magent
tar zxvf magent-0.6.tar.gz
make
报错1:
gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o magent.o magent.c
magent.c: In function 'writev_list':
magent.c:729: error: 'SSIZE_MAX' undeclared (first use in this function)
magent.c:729: error: (Each undeclared identifier is reported only once
magent.c:729: error: for each function it appears in.)
make: *** [magent.o] Error 1
解决办法:
[root@centos6 memcached]# vi ketama.h
#在开头加入
#ifndef SSIZE_MAX
#define SSIZE_MAX 32767
#endif
继续make
报错2:
gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o magent.o magent.c
gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o ketama.o ketama.c
gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o /usr/lib64/libevent.a /usr/lib64/libm.a
gcc: /usr/lib64/libevent.a: No such file or directory
gcc: /usr/lib64/libm.a: No such file or directory
解决办法:
[root@centos6 memcached]# ln -s /usr/lib/libevent* /usr/lib64/
[root@centos6 memcached]# make
报错3:
gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o /usr/lib64/libevent.a /usr/lib64/libm.a
gcc: /usr/lib64/libm.a: No such file or directory
make: *** [magent] Error 1
解决办法:
yum install glibc glibc-devel
如果是64bit的系统则不会在/usr/lib64/libm.a 生成,如果是32bit即会有。
[root@centos6 memcached]# cp /usr/lib64/libm.so /usr/lib64/libm.a
继续make
如果继续上面报错先查看/usr/lib/libm.so是否存在,如不存在可用/lib64/libm.so.6
文件做软连接为/usr/lib/libm.so重复上面步骤解决此问题。
报错4:
gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o /usr/lib64/libevent.a /usr/lib64/libm.a
/usr/lib64/libevent.a(event.o): In function `detect_monotonic':
event.c:(.text+0xc79): undefined reference to `clock_gettime'
/usr/lib64/libevent.a(event.o): In function `gettime':
event.c:(.text+0xd60): undefined reference to `clock_gettime'
collect2: ld returned 1 exit status
make: *** [magent] Error 1
解决办法:
[root@centos6 memcached]# vi Makefile
CFLAGS = -Wall -g -O2 -I/usr/local/include $(M64)
改为:
CFLAGS = -lrt -Wall -g -O2 -I/usr/local/include $(M64)
[root@centos6 memcached]# make
gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o -lrt /usr/lib64/libevent.a /usr/lib64/libm.a
[root@centos6 memcached]# ls 成功
Makefile ketama.c ketama.h ketama.o magent magent-0.6.tar.gz magent.c magent.o
[root@centos6 memcached]# cp magent /usr/bin/
五。启动进程
memcached启动参数描述:
-d :启动一个守护进程,
-m:分配给Memcache使用的内存数量,单位是MB,默认是64MB,
-u :运行Memcache的用户
-l :监听的服务器IP地址
-p :设置Memcache监听的端口,默认是11211 注:-p(p为小写)
-c :设置最大并发连接数,默认是1024
-P :设置保存Memcache的pid文件 注:-P(P为大写)
如果要结束Memcache进程,执行:kill cat pid文件路径
[root@centos6 memcached]# memcached -m 10 -u root -d -l 0.0.0.0 -p 11211
[root@centos6 memcached]# memcached -m 10 -u root -d -l 0.0.0.0 -p 11212
[root@centos6 memcached]# memcached -m 10 -u root -d -l 0.0.0.0 -p 11213
[root@centos6 memcached]# netstat -antp

magent启动
[root@centos6 memcached]# magent -u root -n 51200 -l 192.168.20.122 -p 12000 -s 127.0.0.1:11211 -s 127.0.0.1:11212 -b 127.0.0.1:11213
分别在127.0.0.1机器的11211,11212,11213端口启动3个Memcached进程,在12000端口开启magent代理程序;(以此类推可在不同机器上启动memcached)
11211和11212为主Memcached,11213为备份Memcached;
[root@centos6 memcached]# telnet 192.168.20.159 12000
Trying 192.168.20.159...

END
六。安装php的memcache客户端
下载
wget http://pecl.php.net/get/memcache-2.2.6.tgz
安装
tar zxvf memcache-2.2.6.tgz -C /usr/src/
cd /usr/src/memcache-2.2.6/
ls
/usr/local/php/bin/phpize
./configure --enable-memcache --with-php-config=/usr/local/php/bin/php-config
make && make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/ 出现该行安装成功
修改php.ini
[root@LNMP4 memcache-2.2.6]# vi /usr/local/php/etc/php.ini
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/" 该行修改
extension = memcache.so 该行添
