在 Linux 系统中安装Load Generator ,并在windows 调用
由于公司需要测试系统的最大用户承受能力,所以需要学习使用loadrunner。在安装的时候碰到了不少问题,所以写下此文章总结遇到的问题以及解决方案,希望能帮到大家。也希望大家转载注明出处。Winsows 的Loadrunner 安装就不多讲了,这个太容易了。以下是Linux 中安装 Load Generator 说明:Linux 系统版本:CentOS5.4Load Generator 版本 : Load Generator 11安装步骤如下:1. 到HP官网下载Load Generator 安装文件 Software,_Load_Generator_11.00_T7330-15010.iso2.确保系统安装了c++ , gclib 相关工具(我的系统在安装前已经安装了gclib ,所以还不知道没装这个会发生什么问题)3. 在Windows 系统下将Software,_Load_Generator_11.00_T7330-15010.iso 解压出来会有三个文件夹(HP , Linux , Solaris),这三个文件夹是相关系统的安装包。请根据你的系统选择对应的文件夹copy到 要安装的Linux 系统中。为什么要使用这种解压后copy的原因是因为我根据网上的方法copy iso 文件到Linux 系统中并使用挂载的方式进行安装,碰到了很多问题,所以使用这种方式,这可是我原创的哦。我是copy到/home/LoadRunner/目录下4. 紧跟着就是安装了,只需要执行指令/home/LoadRunner/Linux/installer.sh 会出现如下图中的安装向导欢迎界面,选择Next [n] 即可。
5. 出现下图许可协议界面,也只需点击Agree [a],当然你可以选择View Agreement [v] 查看协议的详细内容
6. 出现确认安装界面,选择Install [i] 即可 7. 出现安装界面如下图 8. 完成安装,选择Finish [f] 即可,恭喜你安装成功 9. 紧跟着就是配制环境了,网上有说要配置env.csh 的,但我安装后env.csh 已经默认配置好了,这里也将的默认配置文件分享一下setenv PRODUCT_DIR /opt/HP/HP_LoadGeneratorsetenv M_LROOT $PRODUCT_DIRif ( `uname` == SunOS ) then
setenv LD_LIBRARY_PATH ${M_LROOT}/binelse if ( `uname` == Linux ) then setenv LD_LIBRARY_PATH ${M_LROOT}/binelse if ( `uname` == AIX ) then setenv LIBPATH ${M_LROOT}/binelse if ( `uname` == HP-UX ) then setenv SHLIB_PATH ${M_LROOT}/binendifsetenv PATH ${M_LROOT}/bin:$PATH
10 .除了上文中讲到的还需要在/root/.bashrc文件中添加如下配制,保存修改后注销用户重用登录
export PRODUCT_DIR=/opt/HP/HP_LoadGenerator export M_LROOT=$PRODUCT_DIR export LD_LIBRARY_PATH=${M_LROOT}/bin export PATH=${M_LROOT}/bin:$PATH11 . Load Generator会安装到/opt/HP/HP_LoadGenerator目录下,我也是使用默认的。进行/opt/HP /HP_LoadGenerator/bin 目录执行./verify_generator (不能使用root用户,至于为什么还不清楚) 检查安装是否成功,如果成功会有以下信息,

讲到这里安装步骤就完,现在讲如何在Windows 系统下启用 刚才安装的Load Generator
1. 打开Controller 的Load Generator 。 点击 场景--> Load Generator
2. 添加一个Load Generator 。点击 添加--> 输入名称(名称即ip)--> 选择平台 --> 点击更多 --> 点击 Unix 环境 --> 勾选“不使用RSH” --> 确定 3. 添加后测试连接,如果显示连接成功就功造成了,连接时如果有其它问题建议大家多思考,注意那些连接不成功的提前。我个人觉得LoadRunner 在提示之方面做的比较好,出了问题基本上看提示就知道问题在哪里。祝大家一切顺利。 http://115.com/file/clg3cm8h
方法二:
Linux下安装LoadRunner(LoadGenerator)
1. 在HP的官方网站上下载LoadRunner9.5 的Linux安装程序[T7177-15009.iso],安装文档[hp_man_LRIG9.50_01_pdf.pdf];
安装程序包括Hp、Ibm、Linux、Solaris系统的支持(LR9.0对应安装文件为[TLRNUX900WC_00.zip])。
2. 安装包的处理:
1. ZIP解压:unzip TLRNUX900WC_00.zip
2. 挂载ISO:mkdir /mnt/LoadRunner ; mount -t iso9660 -o loop T7177-15009.iso /mnt/LoadRunner
3. 开始安装,以LR9.5为例:
/mnt/LoadRunner/Linux/installer.sh
按提示操作,直接Next到完成。
4. 添加用户和环境变量:
useradd -g 0 -s /bin/csh higkoo
cat /opt/HP/HP_LoadGenerator/env.csh > /etc/.login
cat /opt/HP/HP_LoadGenerator/env.csh >~higkoo/.cshrc
touch ~root/.rhosts ~higkoo/.rhosts
5. 检查运行环境(在本机或使用VNC执行):
su - higkoo
cd /opt/HP/HP_LoadGenerator/bin/
./verify_generator
6. 启动服务(用新增的用户higkoo):
cd /opt/HP/HP_LoadGenerator/bin/
./m_daemon_setup start
7. 检查是否启动:
ps aux | grep m_agent_daemon
netstat -naop | grep 54345
8. 注意事项:
开启端口54345或关闭防火墙(service iptables stop)
正确设置后用verify_generator的检测结果是:
./verify_generator =================================================== HP Vuser Environment Verification Utility ===================================================
Product: HP LoadRunner 9.50 Version: 09.50.0000 Build: 3378 higkoolincn100ce5:

Summary: ________ Vuser Host higkoolincn100ce5: OK |
使用Controller连接,在“UNIX Environment Tab”下选择“Don't use RSH ”即可连接Linux负载机。
若使用RSH连接,则负载机必须安装RSH并正确配置,正如检测过程中描述的“Don't forget to make sure that the name of the controller machine”。
补充,Linux下似乎只支持Web/Http协议的脚本。譬如WinSock协议,从名称上都知道只适合Windows:
“Error (-81024): LR_VUG: The 'WinSock' type is not supported on 'Linux' platforms .”
另外试了Java协议,确实不行,报错如下:
Error (-81024): LR_VUG: The 'General-Java' type is not supported on 'Linux' platforms .
依赖库:yum -y --disablerepo=\* --enablerepo=AutoInstaller --nogpgcheck --skip-broken localinstall /mnt/CentOS_Final/CentOS/compat-libstdc++-33-3.2.3-61.i386.rpm
否则会报:m_agent_daemon: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
注意hosts文件的配置,如果机器名和hosts里配置不一致也会导致LoadRunner启动失败,
譬如:Error: Communication error: Failed to get the server host IP by calling the gethostbyname function.。
附上给LoadRunner定制的系统服务脚本(/etc/init.d/loadrunner):
#!/bin/bash
# /etc/init.d/loadrunner# Loadrunner负载生成器服务DAEMON=m_daemon_setupARGV="$@"DIR=/opt/HP/HP_LoadGenerator/bin/USER=higkooUBIT="su - $USER -c "
$UBIT "cd $DIR && ./$DAEMON $ARGV"
运行服务:
service loadrunner start
m_agent_daemon ( 1808 ),
