搭建Memceached服务器

32ew12

                      注意事项：memceached服务器必须要在LNMP环境下使用，这个大家要注意了。


首先把（ memceached-package.zip ）软件包拖到系统的桌面，然后减压。

[iyunv@localhost 桌面]# ls     memceached-package.zip
memceached-package.zip
[iyunv@localhost 桌面]# unzip    memceached-package.zip

切换到减压目录并且查看这个目录下有哪些软件包：

[iyunv@localhost 桌面]# cd   memceached-package
[iyunv@localhost memceached-package]# ls
libevent-2.0.15-stable.tar.gz    memcached-1.4.5.tar.gz

减压（libevent-2.0.15-stable.tar.gz）这个软件包，并且切换到减压后的这个软件包的目录、

[iyunv@localhost memceached-package]# tar  zxf   libevent-2.0.15-stable.tar.gz
[iyunv@localhost memceached-package]# ls
libevent-2.0.15-stable   libevent-2.0.15-stable.tar.gz   memcached-1.4.5.tar.gz
[iyunv@localhost memceached-package]# cd  libevent-2.0.15-stable

现在开始涉足环境和安装，
[iyunv@localhost libevent-2.0.15-stable]#   ./configure
[iyunv@localhost libevent-2.0.15-stable]#   make
[iyunv@localhost libevent-2.0.15-stable]#   make  install

现在回到（memceached-package）目录并且查看这个目录下的软件包：
[iyunv@localhost memceached-package]# cd   /root/桌面/memceached-package
[iyunv@localhost memceached-package]# ls
libevent-2.0.15-stable  libevent-2.0.15-stable.tar.gz  memcached-1.4.5.tar.gz

现在减压这个软件包：
[iyunv@localhost memceached-package]# tar  zxf  memcached-1.4.5.tar.gz
[iyunv@localhost memceached-package]# ls
libevent-2.0.15-stable  libevent-2.0.15-stable.tar.gz  memcached-1.4.5  memcached-1.4.5.tar.gz
[iyunv@localhost memceached-package]# cd   memcached-1.4.5


[iyunv@localhost memcached-1.4.5]#  ./configure
[iyunv@localhost memcached-1.4.5]#  make
[iyunv@localhost memcached-1.4.5]#  make install

启动memcahced 服务：

Libevent.conf这个文件是没有的我们新建，并且要跟新一下。

[iyunv@localhost memcached-1.4.5]# echo  "/usr/local/lib/" >  /etc/ld.so.conf.d/libevent.conf
[iyunv@localhost memcached-1.4.5]# ldconfig   -v

现在就启动服务：

[iyunv@localhost ~]# /usr/local/bin/memcached  -p  11211    -l   192.168.1.2    -m   100MB   -n   10    -f    2   -u  root   -vvv  -d

在客户端上使用（telnet）来测试：

如果没有这个命令就要安装这个命令的软件包了。

[iyunv@localhost ~]#  yum   -y  install   telnet
[iyunv@localhost ~]#  telnet  192.168.1.2   11211
Trying 192.168.1.2...

get  name         #取数据

jim
END
Quit #退出

这个是是武器上的变化：
