支持ipv6的web压力测试工具curl-load
由于工作需要,最近在测试ipv6网络设备,发现支持ipv6测试工具还有点少,于是各种折腾。
备注:对于ipv6组网及ipv6网站架设这里就不累赘了,大家可以网上搜索,现已知的IIS6.0及以上支持IPv6,apache 2.0(Linux版)以上支持,nginx支持。windows 2003的DNS不支持ipv6,2008中的dns支持ipv6。
1、前置条件
(1)本地环境要求
本地环境
[root@dr101 curl-loader-0.56]# cat /etc/redhat-release
CentOS release 6.2 (Final)
[root@dr101 curl-loader-0.56]#
(2)要求安装SSL相关包,gcc、make等工具
在CentOS下安装直接使用yum工具来安装即可,保证你的机器可以上外网
yum install gcc make openssl
官方说明查看地址:
http://curl-loader.sourceforge.net/doc/fast.html
Build it using general C development environment with bash, gcc compiler (3 or 4 series), make, etc on a linux machine.
Building pre-requirements are:
a. openssl binaries;
b. openssl development package with include files (on debian package libssl-dev);
curl-loader介绍
curl-loader(也被称为“omes-NIK”和“davilka”)是一个开源的C语言编写的工具,模拟应用负载和成千上万的几十万人的HTTP / HTTPS和FTP/ FTPS的客户端应用程序的行为,每个有其自己的源IP地址。相反,其他curl-loader使用真正的C编写的客户端协议栈,即libcurl和TLS/ openssl的SSL的HTTP和FTP协议栈,支持登录和验证口味和模拟用户行为的工具。
(3)ipv6地址配置
此处以我测试的系统为例
[root@dr101 curl-loader-0.56]# cat /etc/sysconfig/network-scripts/ifcfg-Auto_eth2
HWADDR=00:0C:29:09:F6:42
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.202.101
PREFIX=24
GATEWAY=192.168.202.1
DNS1=202.102.192.68#如果你有ipv6的DNS,可以将ipv6的DNS也加上,这样后面可以使用域名进行压力测试
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=yes #修改为yes
IPVADDR=fc00:0:0:202::101 #添加ipv6地址,注意IPVADDR不是IPV6ADDR,有点怪异
IPV6_DEFAULTGW=fc00:0:0:202::1#添加默认IPv6网关
NAME="Auto eth2"
UUID=4d4bee9e-f139-4ab0-95e0-57fc7c11cc37
ONBOOT=yes
IPV6_AUTOCONF=no#关闭IPv6自动配置
IPV6ADDR=fc00:0:0:202::101/64#再次设置ipv6地址
IPV6_DEFROUTE=yes#开启ipv6默认路由
IPV6_FAILURE_FATAL=no
GATEWAY=fc00:0:0:202::1#再次设置IPv6网关
[root@dr101 curl-loader-0.56]# ifconfig
eth2 Link encap:Ethernet HWaddr 00:0C:29:09:F6:42
inet addr:192.168.202.101 Bcast:192.168.202.255 Mask:255.255.255.0

[root@dr101 curl-loader-0.56]#
2、下载地址
官方下载地址:http://sourceforge.net/projects/curl-loader/files/curl-loader/
[root@dr101 mysoft]# wget http://ncu.dl.sourceforge.net/project/curl-loader/curl-loader-stable/curl-loader-0.56/curl-loader-0.56.tar.bz2
[root@dr101 mysoft]# tar jvxf curl-loader-0.56.tar.bz2
3、安装
(1)注意,如要是curl-load支持ipv6必须在安装即make之前修改Makefile文件中的如下内容
修改Makefile
将--disable-ipv6改为--enable-ipv6
[root@dr101 curl-loader-0.56]# vi Makefile
# To enable IPv6 change --disable-ipv6 to --enable-ipv6
$(LIBCURL):
cd ./packages; tar jxfv curl-$(CURL_VER).tar.bz2; ln -sf curl-$(CURL_VER) curl; \
patch -d curl -p1 < ../patches/curl-trace-info-error.patch
mkdir -p $(CURL_BUILD);
cd $(CURL_BUILD); ../../packages/curl/configure --prefix=$(CURL_BUILD) \
--without-libidn \
--without-libssh2 \
--disable-ldap \
# To enable IPv6 change --disable-ipv6 to --enable-ipv6#这里提示如果要使curl-load支持ipv6需要开启--enable-ipv6
$(LIBCURL):
cd ./packages; tar jxfv curl-$(CURL_VER).tar.bz2; ln -sf curl-$(CURL_VER) curl; \
patch -d curl -p1 < ../patches/curl-trace-info-error.patch
mkdir -p $(CURL_BUILD);
cd $(CURL_BUILD); ../../packages/curl/configure --prefix=$(CURL_BUILD) \
--without-libidn \
--without-libssh2 \
--disable-ldap \
--enable-ipv6 \#这里默认是--disable-ipv6,需要修改为--enable-ipv6
--enable-thread \
--with-random=/dev/urandom \
--with-ssl=/usr/include/openssl \
--enable-shared=no \
--enable-ares=$(CARES_MAKE_DIR) \
如果不理解,可以看官方文档,即查看解压后文档中的README,并搜索到ipv6:(E文还是要好好学的)
[root@202 curl-loader-0.56]# vi README
NETMASK - netmask for the loading clients IP-addresses (from IP_ADDR_MIN to
IP_ADDR_MAX). For IPv4 you can use either quad-dotted netmask string or CIDR
number from 0-32. For IPv6 only CIDR values from 0 to 128 are supported.
To enable IPv6 change --disable-ipv6 to --enable-ipv6 in Makefile
(2)make and make install
[root@dr101 curl-loader-0.56]# make
[root@dr101 curl-loader-0.56]# make install
mkdir -p /usr/bin
mkdir -p /usr/share/man/man1
mkdir -p /usr/share/man/man5
mkdir -p /usr/share/doc/curl-loader/
cp -f curl-loader /usr/bin
cp -f doc/curl-loader.1 /usr/share/man/man1/
cp -f doc/curl-loader-config.5 /usr/share/man/man5/
cp -f doc/* /usr/share/doc/curl-loader/
cp -rf conf-examples /usr/share/doc/curl-loader/
4、使用curl-load进行测试
由于curl-load没用进行configure步骤,即没有指定安装目录,默认就是当前解压目录,比如我这里的/home/mysoft/curl-load-0.56
(1)配置文件存放路径
[root@dr101 conf-examples]# pwd
/home/mysoft/curl-loader-0.56/conf-examples
[root@dr101 conf-examples]# ls
10K.conf https.conf
60K.conf ipv6.conf
bax.conf log-hdr-body.conf
bax-login-logoff-noncycling.conf login-uas-cycling.conf
bax-logs.conf login-uas-logoff-cycling.conf
big-load.conf multipart-formdata-post.conf
bulk.conf post-form-tokens-fr-file.conf
bulk-dual-url.conf post-xml.conf
credentials.cred put.conf
custom-hdrs.conf random_file_records.conf
delete.conf rate-limit.conf
fetch-probability.conf resp-errors.conf
fetch-probability-once.conf some.xml
ftp.conf timers-random-range.conf
ftp-http.conf url-randomize.conf
ftp-upload.conf url-template-file.txt
get-forms.conf url-template-fr-file.conf
get-post-login.conf url-template-resp-dynamic.conf
get-post-login-cycling.conf
[root@dr101 conf-examples]#
(2)修改ipv6配置文件
本次主要是使用curl-load进行ipv6 web服务器的测试工作,于是修改ipv6.conf文件
[root@dr101 conf-examples]# vi ipv6.conf
########### GENERAL SECTION ################################
BATCH_NAME= ipv6
CLIENTS_NUM_MAX = 20 #10000
INTERFACE =eth2 #需要修改为你进行ipv6通信的接口,不知道了,用ifconfig查看
NETMASK=64
IP_ADDR_MIN= fc00:0:0:202::111 #2001:db8:fff5:6::101,IP_ADDR_MIN &MAX是用来指定ipv6地址范围的,必须和物理接口的ipv6地址在一个网段,同时没有被其他主机使用
IP_ADDR_MAX= fc00:0:0:202::130 #2001:db8:fff5:6::103 #2001:db8:fff5:ffff::1
IP_SHARED_NUM=20 #上面写了地址范围,但是不是每个地址都会用上的,这里就是指明使用上面ipv6地址范围中多少个地址用来进行测试,curl-load会在本地网卡上绑定一批ipv6的地址
CYCLES_NUM= -1
URLS_NUM = 1
########### URL SECTION ####################################
URL= http://[fc00:0:0:216::11]/hunlian.htm #http://ip6-localhost/apache2-default/index.html 填写要测试的URL,当然URL也可以是一个文件中的多个url,注意ipv6webURL的写法,如果你使用了域名,可以直接用域名进行测试
REQUEST_TYPE=GET
TIMER_URL_COMPLETION = 0 # In msec. When positive, Now it is enforced by cancelling url fetch on timeout
TIMER_AFTER_URL_SLEEP =300 #默认为1000
(3)进行简单测试
[root@dr101 curl-loader-0.56]# ./curl-loader -f conf-examples/ipv6.conf
会先绑定一下ipv6地址到eth2上
这下err的错误少了,有了2XX即成功的请求了
============ loading batch is: ipv6 ======================================

ctrl+c来结束测试
此时再开窗口,可以看到接口上绑定了很多ipv6的地址
[root@dr101 ~]# ifconfig

如何去掉这些绑定的ipv6呢?
这些地址是临时加上去的,可以重启网卡service network restart来实现。
5、一些参数说明
(1)配置参数
########### GENERAL SECTION ################################
BATCH_NAME= baidu //测试对象的名称
CLIENTS_NUM_MAX=20 //最大虚拟用户数
CLIENTS_NUM_START=1 //一开始启动用户数
CLIENTS_RAMPUP_INC=1 //每秒钟启动几个用户
INTERFACE =eth0 //使用的网卡eth0
NETMASK=16 //子网掩码位数
IP_ADDR_MIN= 192.168.1.1 //起始IP地址
IP_ADDR_MAX= 192.168.53.255 #Actually - this is for self-control //最后的IP地址范围
CYCLES_NUM= -1 // -1 表示无限循环
URLS_NUM= 1
########### URL SECTION ####################################
URL=http://www.baidu.com/index.html //要测试的URL
#URL=http://localhost/ACE-INSTALL.html
URL_SHORT_NAME="local-index"
REQUEST_TYPE=GET
TIMER_URL_COMPLETION = 5000 # In msec. When positive, Now it is enforced by cancelling url fetch on timeout
TIMER_AFTER_URL_SLEEP =20
(2)结果参数
各项参数说明:
interval stats 间隔统计
latest 最新数据(3秒内的)
clients 并发用户数量
CAPS-curr 最新发送请求数
req: request (请求)
- 1xx成功NUM; - 2xx成功NUM;- 3xx的重定向数量;- 4xx客户端错误数;- 5xx服务器错误数;
平均2XX(成功)的HTTP响应中的应用服务器延时,如上,但只有2xx有应答。来推动是3xx的重定向和5xx服务器错误/拒绝未必能真实反映一个测试服务器工作的功能(D2XX);
Ti (T-in) 吞吐量“吞”,平均值,字节/每秒
To (T-out) 吞吐量“吐”,平均值,字节/每秒
Summary stats 总结统计
runs 运行时间
CAPS-average 总平均发送请求数(秒)
错误类型:
err - 其他NUM错误,如解析,TCP连接,服务器关闭或空响应;
T-err - URL完成时间到期的错误;

6、弯路及错误解决方法
如果不修改Makefile
即不将将--disable-ipv6改为--enable-ipv6就进行make && make install
可以看到全是Err的错误,看不到2XX
