PowerDNS 压力测试
DNS服务器搭建好了，我们来压力测试一下。
测试工具
- queryperf （bind下的）
- dnsperf
我们选用queryperf
安装
1.下载
wget https://www.isc.org/downloads/file/bind-9-12-2-p1/?version=tar-gz
#下载下来的文件名字不是个tar包
#index.html\?version\=tar-gz
#重命名
mv index.html\?version\=tar-gz bind.tar.gz
下载地址，bind downlocads
2.编译
#step 1
tar -zxvf bind.tar.gz
#step 2
cd bind-9.12.2-P1/
cd contrib/queryperf/
ls
#=============================

#step 3
./configure #可以./configure -h 查看帮助
#step 4
make
#step 5
sudo cp queryperf /usr/bin/
参数解释
- -d: 后面接上一个文件，文件的内容是用户对DNS的请求，一行为一条请求。发多少个查询就写多少条
- -s: DNS服务器地址
- -p: DNS服务器端口

Usage: queryperf [-d datafile] [-s server_addr] [-p port] [-q num_queries]
[-b bufsize] [-t timeout] [-n] [-l limit] [-f family] [-1]
[-i interval] [-r arraysize] [-u unit] [-H histfile]
[-T qps] [-e] [-D] [-R] [-c] [-v] [-h]
-d specifies the input data file (default: stdin)
-s sets the server to query (default: 127.0.0.1)
-p sets the port on which to query the server (default: 53)
-q specifies the maximum number of queries outstanding (default: 20)
-t specifies the timeout for query completion in seconds (default: 5)
-n causes configuration changes to be ignored
-l specifies how a limit for how long to run tests in seconds (no default)
-1 run through input only once (default: multiple iff limit given)
-b set input/output buffer size in kilobytes (default: 32 k)
-i specifies interval of intermediate outputs in seconds (default: 0=none)
-f specify address family of DNS transport, inet or inet6 (default: any)
-r set RTT statistics array size (default: 50000)
-u set RTT statistics time unit in usec (default: 100)
-H specifies RTT histogram data file (default: none)
-T specify the target qps (default: 0=unspecified)
-e enable EDNS 0
-D set the DNSSEC OK bit (implies EDNS)
-R disable recursion
-c print the number of packets with each rcode
-v verbose: report the RCODE of each response on stdout
-h print this usage
