项目中需要用到Memcached,前期的测试,都是在Win上做的.而我们的服务器却是Solaris的.为了测试在Solaris上的性能.则需要在服务器上安装Memcached.因为之前没有弄过这个东西,所以安装的过程也遇到了很多的问题.
????
还好在Solaris下,有一个专门的工具Cool Stack,它是一个Apache,PHP,MySql的简易安装包.现在的版本是1.3.1.很庆幸,在这个安装包中,同样也包含Memcached.
从http://cooltools.sunsource.net/coolstack/下载Cool Stack的运行环境和Memcached的安装包.
分别是:CSKruntime_1.3.1_i386.pkg.bz2和CSKmemcached_1.3.1_i386.pkg.bz2.
下载后上传到Solaris上.
之后进行解压.
bunzip2 CSKruntime_1.3.1_i386.pkg.bz2
bunzip2 CSKmemcached_1.3.1_i386.pkg.bz2
解压后,
使用Root账号登录.
之后使用pkgadd来安装两个包,记住要加-d.
pkgadd -d CSKruntime_1.3.1_i386.pkg
pkgadd -d CSKmemcached_1.3.1_i386.pkg
很容易的就安装成功了.
之后进入到目录:/opt/coolstack/bin中.
你就会看到目录里有一个memcached了.
执行./memcached -h
如果你能看到像下面的内容一样,就证明你安装成功了.

哈.现在你可以将Memcached启动起来进行测试啦.
./memcached -d -m 2048 -l 10.10.13.240 -P 11211???
关于Memcached的使用.网上有很多教程.
可以参见.
PS:这两天被这个问题给郁闷坏了.
新装的Solaris服务器.
要安装Memcached,首先要安装libevent.
网上提供的都是需要自己编译,安装的.
这就需要在系统中安装gcc和make.
装这两个东西倒没有什么问题.
可是在安装libevent的时候,遇到了好多的问题.
做C的同事也帮着弄了好久,才勉强将它安装上,其间还改了源代码....
可是Memcached却始终提示找不到libevent.
无论你是否指定libevent的路径.都不行.
我在自己的Ubuntu上装了一下,一点问题也没有.
快要放弃的时候,在Sun的网站上看到了可以使用Cool Stack来安装Memcached.
才让自己看了希望.
还好,功夫不负有心人.
现在已经开始进行Memcached的测试了.
终于把这个狗屎问题解决了.
