linux Memcached服务端安装

1、安装Memcached服务端

1) 手工安装

a) 安装libevent库

Debian/Ubuntu: apt-get install libevent-dev

Redhat/Centos: yum install libevent-devel

b) 下载解压并安装

wget https://memcached.org/latest

[you might need to rename the file]

tar -zxf memcached-1.x.x.tar.gz

cd memcached-1.x.x

./configure --prefix=/usr/local/memcached

make && make test && sudo make install

ln -s /usr/local/memcached/bin/memcached /usr/bin/memcached /bin/cp scripts/memcached.sysv /etc/init.d/memcached sed -i 's@^USER=.*@USER=root@' /etc/init.d/memcached sed -i 's@chown@#chown@' /etc/init.d/memcached sed -i 's@/var/run/memcached/memcached.pid@/var/run/memcached.pid@' /etc/init.d/memcached sed -i 's@^prog=.*@prog="/usr/local/memcached/bin/memcached"@' /etc/init.d/memcached #前面有软链接，这里可以省略 chmod +x /etc/init.d/memcached chkconfig --add memcached chkconfig memcached on cd ..

   2) 自动安装
   For Debian or Ubuntu: apt-get install memcached
   For Redhat/Fedora: yum install memcached

编译安装结果打印

[root@localhost memcached-1.4.37]# make install

make install-recursive

make[1]: 进入目录“/data/software/memcached-1.4.37”

Making install in doc

make[2]: 进入目录“/data/software/memcached-1.4.37/doc”

make install-am

make[3]: 进入目录“/data/software/memcached-1.4.37/doc”

make[4]: 进入目录“/data/software/memcached-1.4.37/doc”

make[4]: 对“install-exec-am”无需做任何事。

/usr/bin/mkdir -p '/usr/local/memcached/share/man/man1'

/usr/bin/install -c -m 644 memcached.1 '/usr/local/memcached/share/man/man1'

make[4]: 离开目录“/data/software/memcached-1.4.37/doc”

make[3]: 离开目录“/data/software/memcached-1.4.37/doc”

make[2]: 离开目录“/data/software/memcached-1.4.37/doc”

make[2]: 进入目录“/data/software/memcached-1.4.37”

make[3]: 进入目录“/data/software/memcached-1.4.37”

/usr/bin/mkdir -p '/usr/local/memcached/bin'

/usr/bin/install -c memcached '/usr/local/memcached/bin'

/usr/bin/mkdir -p '/usr/local/memcached/include/memcached'

/usr/bin/install -c -m 644 protocol_binary.h '/usr/local/memcached/include/memcached'

make[3]: 离开目录“/data/software/memcached-1.4.37”

make[2]: 离开目录“/data/software/memcached-1.4.37”

make[1]: 离开目录“/data/software/memcached-1.4.37”

2、启动Memcached

1) service memcached start #或者执行下面

2) memcached -p 11211 -l 127.0.0.1 -d -u root -P /var/run/memcached.pid -m 64M -c 1024

3) 几个参数的解释：

-p memcached监听的TCP端口
-l 监听的ip地址，127.0.0.1是本机，当然也可以写上你的服务器IP，如：10.0.0.10，这是我服务器的IP地址，如果你需要多个服务器都能够读取这台memcached的缓存数据，那么就必须设定这个ip
-d 以daemon方式运行，将程序放入后台
-u memcached的运行用户，我设定的是nobody
-P memcached的pid文件路径
-m memcached可以使用的最大内存数量
-c memcached同时可以接受的最大的连接数

如果你希望以socket方式来访问memcached，那么在启动的时候就必须去掉 -l和-p参数，并加上-s参数：

-s memcached的socket文件路径
