centos5 安装 tsung
因要使用tsung对openfire做压力测试，tsung依赖erlang，导致首次安装tsung即失败。已安装的centos5并不包含erlang开发包，下载到 otp_src_R12B-5.tar.gz 解压后进入到解压后目录，按照说明步骤：./configure 结果前面看着刷一堆的日志，一切OK，但到最后出现两行错误：
checking for tgetent in -lncurses... no
checking for tgetent in -lcurses... no
checking for tgetent in -ltermcap... no
checking for tgetent in -ltermlib... no
configure: error: No curses library functions found
configure: error: /bin/sh '/opt/of/software_temp/otp_src_R12B-5/erts/configure' failed for erts
折腾了半天发现是缺少erlang的依赖ncurses，因为是centos，先查看缺失哪个。命令一看，有些还是有的，但也缺少一部分。
yum list|grep ncurses
根据缺失的组件情况，再安装ncuses缺少组件
yum -y install ncurses-devel 安装成功后，再到erlang解压目录下./configure 一切正常，再执行:make也正常，但到make install 又出错：
make: Entering directory `/opt/evas/software_temp/otp_src_R12B-5/lib/common_test/c_src'
../priv/build_rx_lib ../priv make
make: execvp: ../priv/build_rx_lib: Permission denied
make: *** Error 127

这个问题就比较好找了，根据上面的路径找到lib/common_test/priv 目录，来个暴力的，在该目录下：chmod 777 build_rx_lib ，再执行make install 一切正常了。接下来就是继续安装tsung, ./configure,make,make install 一切正常，终于把这玩意给安装好了。在ubuntu上安装tsung省事多了。
