memcached安装

uytyrt

一、安装memcached
1、分别把memcached和libevent下载回来，放在/data/src目录下
cd /data/src
wget https://github.com/libevent/libe ... 2.1.8-stable.tar.gz
wget http://www.memcached.org/files/memcached-1.4.34.tar.gz

2、先安装libevent
tar zxvf libevent-2.1.8-stable.tar.gz
cd libevent-2.1.8-stable
./configure --prefix=/usr/
make
make install

3、测试libevent是否安装成功
ll /usr/lib | grep libevent
lrwxrwxrwx   1 root root      21 Feb 14 10:42 libevent-2.1.so.6 -> libevent-2.1.so.6.0.2
-rwxr-xr-x   1 root root 1128436 Feb 14 10:42 libevent-2.1.so.6.0.2
-rw-r--r--   1 root root 1817720 Feb 14 10:42 libevent.a
lrwxrwxrwx   1 root root      26 Feb 14 10:42 libevent_core-2.1.so.6 -> libevent_core-2.1.so.6.0.2
-rwxr-xr-x   1 root root  722476 Feb 14 10:42 libevent_core-2.1.so.6.0.2
-rw-r--r--   1 root root 1194990 Feb 14 10:42 libevent_core.a
-rwxr-xr-x   1 root root     969 Feb 14 10:42 libevent_core.la
lrwxrwxrwx   1 root root      26 Feb 14 10:42 libevent_core.so -> libevent_core-2.1.so.6.0.2
lrwxrwxrwx   1 root root      27 Feb 14 10:42 libevent_extra-2.1.so.6 -> libevent_extra-2.1.so.6.0.2
-rwxr-xr-x   1 root root  426194 Feb 14 10:42 libevent_extra-2.1.so.6.0.2
-rw-r--r--   1 root root  622802 Feb 14 10:42 libevent_extra.a
-rwxr-xr-x   1 root root     976 Feb 14 10:42 libevent_extra.la
lrwxrwxrwx   1 root root      27 Feb 14 10:42 libevent_extra.so -> libevent_extra-2.1.so.6.0.2
-rwxr-xr-x   1 root root     934 Feb 14 10:42 libevent.la
lrwxrwxrwx   1 root root      30 Feb 14 10:42 libevent_pthreads-2.1.so.6 -> libevent_pthreads-2.1.so.6.0.2
-rwxr-xr-x   1 root root   18502 Feb 14 10:42 libevent_pthreads-2.1.so.6.0.2
-rw-r--r--   1 root root   18694 Feb 14 10:42 libevent_pthreads.a
-rwxr-xr-x   1 root root     997 Feb 14 10:42 libevent_pthreads.la
lrwxrwxrwx   1 root root      30 Feb 14 10:42 libevent_pthreads.so -> libevent_pthreads-2.1.so.6.0.2
lrwxrwxrwx   1 root root      21 Feb 14 10:42 libevent.so -> libevent-2.1.so.6.0.2

ok，安装成功了

4、安装memcached，同时需要安装中指定libevent的安装位置
tar zxvf memcached-1.4.34.tar.gz
cd memcached-1.4.34
./configure --with-libevent=/usr/
make
make install

如果中间出现报错，请仔细检查错误信息，按照错误信息来配置或者增加相应的库或者路径。
安装完成后会把memcached放到 /usr/local/bin/memcached

5、测试是否成功安装memcached
ll /usr/local/bin/mem*
-rwxr-xr-x 1 root root 456873 Feb 14 10:43 /usr/local/bin/memcached

二、启动memcached
1、启动memcached服务器端
/usr/local/bin/memcached -d -m 10 -u root -l 10.132.162.106 -p 11211-c 256 -P /usr/local/memcached/memcached.pid

-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192.168.0.200，
-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，

2.如果要结束Memcache进程，执行
kill `cat /tmp/memcached.pid`

也可以启动多个守护进程，不过端口不能重复

三、测试memcached
[iyunv@jstwgm7vr6c8s3 local]# telnet 10.132.162.106 11211
Trying 10.132.162.106...

set key1 0 60 4

get key1
VALUE key1 0 4
1234
