#如上，提示错误，解决方法：安装perl-Test-Pod
[root@localhost otp_src_17.1]# yum install perl-Test-Pod
#继续安装Template Toolkit
[root@localhost Template-Toolkit-2.25]# make test
[root@localhost Template-Toolkit-2.25]# make install
步骤5、#安装perl的gnuplot
[root@localhost software]# tar -xvf gnuplot-4.0.0.tar.gz
[root@localhost software]# cd gnuplot-4.0.0
[root@localhost gnuplot-4.0.0]# ./configure --prefix=/usr/local/gnuplot
[root@localhost gnuplot-4.0.0]# make && make install
...
touch: missing file operand
Try `touch --help' for more information.
../mkinstalldirs /usr/local/gnuplot/info
mkdir -p -- /usr/local/gnuplot/info
/usr/bin/install -c -m 644 gnuplot.info /usr/local/gnuplot/info/gnuplot.info
/usr/bin/install: cannot stat `gnuplot.info': No such file or directory
make[1]: *** [install-info] Error 1

#如上，提示错误，解决方法：安装texinfo
[root@localhost otp_src_17.1]# yum install texinfo
#继续安装perl的gnuplot
[root@localhost gnuplot-4.0.0]# make && make install
步骤6、安装mathplotlib
[root@localhost otp_src_17.1]# yum list | grep matplotlib
[root@localhost otp_src_17.1]# yum install python-matplotlib
#配置环境变量
[root@localhost otp_src_17.1]vi /etc/profile
[root@localhost otp_src_17.1]source /etc/profile
#验证tsplot是否安装成功
[root@localhost otp_src_17.1]# tsplot
Traceback (most recent call last):
File "/usr/local/tsung/bin/tsplot", line 45, in

raise ImportError("Gtk* backend requires pygtk to be installed.")
ImportError: Gtk* backend requires pygtk to be installed.
#如上，提示错误，解决方法：安装pygtk
[root@localhost otp_src_17.1]# yum install pygtk2
#再次验证tsplot是否安装成功
[root@localhost gnuplot-4.0.0]# tsplot

#如上，提示错误，原因再远tsplot只能在中断terminal中运行，解决方法：安装桌面
[root@localhost otp_src_17.1]# yum grouplist | grep X
Legacy UNIX compatibility
Legacy X Window System compatibility
TeX support
X Window System
Xhosa Support
[root@localhost otp_src_17.1]# yum groupinstall "X Window System"
#注意这里还得再安装Desktop,否则startx报错
[root@localhost otp_src_17.1]# yum groupinstall Desktop
startx，桌面下使用，，见后文
步骤7、#关闭selinux(不关闭的话可能会话连接数等会被限制，上不去)
#查看selinux状态
[root@localhost ~]# /usr/sbin/sestatus -v
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
……….
#关闭(修改/etc/selinux/config，将SELINUX=enforcing改为SELINUX=disabled)
[root@localhost ~]# vi /etc/selinux/config
...
#SELINUX=enforcing
#modified by laiyu
SELINUX = disabled
# SELINUXTYPE= can take one of these two values:
...
[root@localhost ~]# reboot
步骤8、#修改ulimit
说明：tsung.xml配置文件中，有个maxusers参数，用于突破由单一进程打开的socket最大数限制(缺省的，任意OS上为1024)和select系统调用可扩展性的不足。当用户数更限制更高时，将开启新的erlang虚拟机来处理新用户。默认的maxusers属性值为800.现在，有了内核轮询的允许，可以且应该为maxusers使用一个更大的值，比如300000，且不会有性能损失。但是需要提搞os的limit值
[root@localhost ~]# ulimit –n
1024
[root@localhost ~]# vi /etc/security/limits.conf
...
#ftp hard nproc 0
#@student - maxlogins 4
#added by laiyu#添加以下两行
* soft nofile 65535
* hard nofile 65535
# End of file
步骤9、#实现免SSH密码登录(用于分布式集群，可暂时不设置)
步骤10、#配置文件
#创建默认的配置文件目录、日志文件目录
[root@localhost examples]# mkdir -p ~/.tsung/log
#设置报告生成工具的路径（将日志分析程序复制到tsung/bin下，方便使用）
[root@localhost ~]# find / -name tsung_stats.pl
/usr/local/tsung/lib/tsung/bin/tsung_stats.pl
/root/software/tsung-1.5.1/src/tsung_stats.pl
[root@localhost ~]# cp /usr/local/tsung/lib/tsung/bin/tsung_stats.pl /usr/local/tsung/bin/
#复制自带的例子到配置文件目录
[root@localhost examples]# cp -rp /usr/local/tsung/share/doc/tsung/examples ~/.tsung/
#拿注册功能为例进行测试，配置tsung.xml文件
[root@localhost .tsung]# cp examples/jabber_register.xml ~/.tsung/tsung.xml
步骤11、#启动测试
[root@localhost ~]# tsung -f ~/.tsung/tsung.xml -l ~/.tsung/log/ start
Starting Tsung
"Log directory is: /root/.tsung/log/20140903-1531"
"Maximum number of concurrent users in a single VM reached and 'use_controller_vm' is true, can't start new beam !!! Check 'maxusers' value in configuration.~n"
^C
BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
(v)ersion (k)ill (D)b-tables (d)istribution
a
说明：
tsung –f 指定运行时使用的配置文件( 默认 ~/.tsung/tsung.xml)
tsung –l 指定日志路径( 默认~/.tsung/log/ )
#如上，报错了,解决方法，修改配置文件，如下，打开配置文件，增加maxusers属性
[root@localhost ~]# vi ~/.tsung/tsung.xml
修改如下
[root@localhost ~]# tsung -f ~/.tsung/tsung.xml -l ~/.tsung/log/ start
Starting Tsung
"Log directory is: /root/.tsung/log/20140903-1544"
。。。好了
步骤12、#生成测试报告
[root@localhost ~]# cd ~/.tsung/log/20140903-1544 #进入日志文件目录
[root@localhost 20140903-1544]# tsung_stats.pl
creating subdirectory data
creating subdirectory gnuplot_scripts

#获取报告
[root@localhost 20140903-1544]# cd ..

把test.tar下载到本地，解压，然后打开html文件即可
日志错误：Could not find/open font when opening font "arial"解决方法
问题描述
如图，查看生成日志文件gnuplot.log，发现有错误提示提示
Could not find/open font when opening font "arial", using internal non-scalable
解决方法
在linux中添加arial字体
widonws下载字体文件到Linux
步骤1、打开C:\WINDOWS\Fonts，找到Arial,右键，复制到指定文件夹下
步骤2、
[root@localhost ~]# mkdir/usr/share/fonts/arial
用类似xshell等工具，把刚才复制的字体上传到指定新建的arial目录下。
步骤3、设置环境变量
[root@localhost ~]# vi ~/.bash_profile
如下，添加如下红色的部分的字体
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
export GDFONTPATH=/usr/share/fonts/arial
export GNUPLOT_DEFAULT_GDFONT="arial"
PATH=$PATH:$HOME/bin
export PATH
保存，然后执行source命令
[root@localhost ~]# source .bash_profile
#也可以如下方式生成图形
tsplot “name” log_path –d output_dir
#获取图形报告
[root@localhost log]# ls

[root@localhost log]# mkdir output
[root@localhost log]# mv *.png output
[root@localhost log]# tar -cvf output.tar output
下载output.tar，然后解压，然后查看.png图片
