CentOS make install memcached server (revised)

在centos手动安装 memcached server.

####安装的时候报这个错的解决如下:

If it's already installed, specify its path using --with-libevent=/dir/

sudo yum -y install libevent-devel

####下载安装文件

wget -c http://memcached.googlecode.com/files/memcached-1.4.15.tar.gz
tar xzf memcached-1.4.15.tar.gz
cd memcached-1.4.15
./configure --prefix=/usr/local/memcached

sudo make 
sudo make install

####手动启动

sudo /usr/local/memcached/bin/memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211 -c 1024 -P /tmp/memcached.pid
-d选项是启动一个守护进程
-m分配给Memcache使用的内存数量,单位是MB
-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,最好是1024以上的端口
-c最大运行的并发连接数,默认是1024,按照你服务器的负载量来设定
-P设置保存Memcache的pid文件

####service启动

sudo wget http://www.centos.bz/wp-content/uploads/2011/11/memcached -O /etc/init.d/memcached
sudo chmod +x /etc/init.d/memcached

###创建配置文件
sudo vi /usr/local/memcached/memcached.conf

PORT="11211"     #启动的端口
USER="memcached" #使用的用户
MAXCONN="2048"   #最大并发连接
CACHESIZE="1024" #最大使用内存
OPTIONS=""

###建立用户memcached,加入启动项,并启动memcached

因为之前不是用root用户创建的,所以现在转入root中创建组
$ su -
# groupadd memcached
# useradd -g memcached memcached
# chkconfig --add memcached
# chkconfig memcached on
# service memcached start
# service memcached status


# netstat -lanpt|grep 11211
tcp        0      0 0.0.0.0:11211               0.0.0.0:*                   LISTEN      17514/memcached     
tcp        0      0 :::11211                    :::*                        LISTEN      17514/memcached     

done!
