memaslap的安装方法

前言：

memcache自带的memslap功能无法满足性能测试需要。google以后找到了更为强大的工具memaslap（没错就是多了一个“a”）。

具体功能见：http://docs.libmemcached.org/bin/memaslap.html

但是在安装过程中不断碰壁，于是将安装过程记录如下

Step1：下载安装包

memaslap是 libmemcached的一个组件，因此需要编译安装。首先需要下载libmemcached。

下载地址：https://launchpad.net/libmemcached/+download

Step2：解压编译

./configure --enable-memaslap

make （这个时候问题来了，遇到以下报错）

In file included from ./libmemcached/common.h:92,
                 from libmemcached/allocators.cc:38:

关键信息：error: tr1/cinttypes: No such file or directory

报错原因：libmemcached需要 gcc 4.2 以上版本才可编译，而centos 5.4 的gcc版本只有4.1 ，详见：https://bugs.launchpad.net/libmemcached/+bug/1076181

解决方法：安装gcc44的扩展包，详见：http://gearman.info/build/centos5-8.html

解决步骤引用如下：

wget http://mirrors.ustc.edu.cn/fedora/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
yum -y -q install boost141-devel
ln -s /usr/include/boost141/boost/ /usr/include/boost
export LDFLAGS="-L/usr/lib64/boost141"
export LD_LIBRARY_PATH=/usr/lib64/boost141:$LD_LIBRARY_PATH
yum -y -q install e2fsprogs-devel e2fsprogs
yum -y -q install gcc44 gcc44-c++
export CC="gcc44"
export CXX="g++44"

 所有操作完成后，重新执行：

./configure --enable-memaslap && make && make install

安装完成！！
