源码安装bind
1.准备源码包:
bind官网:http://www.isc.org/downloads/bind/
[root@dns1 ~]#ll
-rw-r--r-- 1 root root 8356463 Dec 11 11:16 bind-9.10.1-P1.tar.gz
2.编译环境正常,未安装rpm的bind程序包
[root@dns1 ~]#yumgroupinstall Development tools
[root@dns1 ~]#yumgroupinstall Server Platform Development
[root@dns1 ~]# rpm-qa bind
[root@dns1 ~]#
3.编译安装源码包:
解压源码:
[root@dns1 ~]#tar jxf bind-9.10.1-P1.tar.gz
[root@dns1 ~]#cd bind-9.10.1-P1
[root@dns1bind-9.10.1-P1]#
可以从中获取帮助:
[root@dns1bind-9.10.1-P1]#./configure --help |less
编译:设置安装路径,程序配置文件路径,禁用Ipv6,禁用chroot,允许多线程
[root@dns1bind-9.10.1-P1]#./configure --prefix=/usr/local/bind --sysconfdir=/etc/named/ --disable-ipv6 --disable-chroot --enable-threads
我这里编译出现了错误,依赖openssl-devel的包:
[root@dns1bind-9.10.1-P1]#yum install openssl-devel
重新编译:
[root@dns1bind-9.10.1-P1]#./configure --prefix=/usr/local/bind --sysconfdir=/etc/named/ --disable-ipv6 --disable-chroot --enable-threads
安装程序:
[root@dns1bind-9.10.1-P1]#make && make install
4.尽量加入系统用户named来管理bind
[root@dns1 ~]#groupadd -r -g 53 named
[root@dns1 ~]# useradd-r -g named -u 53 named
5.下面即将进行的步骤:
导出程序路径至PATH中
导出帮助文件
导出库文件和头文件:
如果开发没用使用其中的库就不用导出
[root@dns1 ~]#ls /usr/local/bind/sbin/
arpaname dnssec-revoke lwresd named-rrchecker
ddns-confgen dnssec-settime named nsec3hash
dnssec-dsfromkey dnssec-signzone named-checkconf rndc
dnssec-importkey dnssec-verify named-checkzone rndc-confgen
dnssec-keyfromlabel genrandom named-compilezone tsig-keygen
dnssec-keygen isc-hmac-fixup named-journalprint
[root@dns1 ~]#ls /usr/local/bind/bin/
bind9-config delv dig host isc-config.sh nslookup nsupdate
[root@dns1 ~]#vim .bash_profile
PATH=$PATH:$HOME/bin:/usr/local/bind/bin:/usr/local/bind/sbin
[root@dns1 ~]#source .bash_profile
6.源码安装是没有任何配置文件和服务脚本的哦!
#ls/etc/named/ 主配置文件
#ls/var/named/ 区域解析库文件
#ls/etc/rc.d/init.d 启动脚本
我们自己来编写配置文件和服务脚本哦!
[root@dns1 ~]#mkdir /var/named
[root@dns1 ~]#cd /var/named
访问一个能访问的DNS获取根区域文件:
[root@dns1named]# dig -t NS . @172.16.0.1 >/var/named/named.ca
[root@dns1named]# ls
named.ca
编辑好本地解析库文件:
[root@dns1 named]# vim named.localhost
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H) ; minimum
NS @
A 127.0.0.1
[root@dns1 named]#vi named.loopback
$TTL 1D
@ IN SOA @ rname.invalid. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H) ; minimum
NS @
A 127.0.0.1
PTR localhost.
权限设置和设置属组为named:
[root@dns1 named]# chmod 640 *
[root@dns1 named]# chown :named *
[root@dns1 named]# ll
total 12
-rw-r----- 1 root named 2100 Dec 11 11:56named.ca
-rw-r----- 1 root named 374 Dec 11 11:57 named.localhost
-rw-r----- 1 root named 401 Dec 11 11:58 named.loopback
提供主配置文件:named.conf
先设置好rndc密钥配置文件:
[root@dns1 named]# rndc-confgen -r /dev/urandom> /etc/named/rndc.conf
需要将rndc密钥文件配置在named.conf文件中:
[root@dns1 named]# cat /etc/named/named.conf
options {
directory "/var/named";
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
# Use with the following in named.conf,adjusting the allow list as needed:
key"rndc-key" {
algorithm hmac-md5;
secret "4a8/AsRRQ5OH5a0oRaBeAg==";
};
#
controls{
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};
#End of named.conf
设置好文件的权限和属组:
[root@dns1 named]# chmod 640 /etc/named/*
[root@dns1 named]# chown :named /etc/named/*
[root@dns1 named]# ll /etc/named/
total 12
-rw-r----- 1 root named 2389 Dec 11 11:29bind.keys
-rw-r----- 1 root named 545 Dec 11 12:09 named.conf
-rw-r----- 1 root named 479 Dec 11 12:01 rndc.conf
7.到这里我们其实可以启动named服务了!
但是有些复杂,只说一些命令哦!
查看帮助文件
#ls /usr/local/bind9/share/man
#man -M /usr/local/bind9/share/man named
前台启动,日志也在前台记录
[root@dns1 named]# named -u named –g
使其在后台运行:
[root@dns1 named]# named -u named
查看启动状态:
[root@dns1 named]# ss -tunl |grep :53
udp UNCONN 0 0 172.16.31.100:53 *:*
udp UNCONN 0 0 127.0.0.1:53 *:*
tcp LISTEN 0 10 172.16.31.100:53 *:*
tcp LISTEN 0 10 127.0.0.1:53 *:*
tcp LISTEN 0 128 :::53887 :::*
[root@dns1 named]# ps aux |grep named
named 18870 0.0 1.1 13××× 11848 ? Ssl 12:23 0:00 named -u named
root 18883 0.0 0.0 103252 824 pts/1 S+ 12:24 0:00 grep named
关闭named服务:
[root@dns1 named]# killall named
[root@dns1 named]# ps aux |grep named
root 18887 0.0 0.0 103252 824 pts/1 S+ 12:24 0:00 grep named
8.我们现在来实现加入区域:
[root@dns1 named]# vim /etc/named/named.conf
zone "oracle.com" IN {
type master;
file "oracle.com.zone";
};
设置区域正向区域解析库文件:
[root@dns1 named]#vim /var/named/oracle.com.zone
$ORIGIN oracle.com.
@ IN SOA ns.oracle.com. root.oracle.com. (
2014121101 ;serial
1D ;refresh
5M ;retry
1W ;expiry
1H) ;minimum
@ IN NS ns.oracle.com.
IN MX 5 mail.oracle.com.
ns IN A 172.16.31.100
www IN A 172.16.31.100
www IN A 172.16.31.101
mail IN A 172.16.31.100
pop3 IN CNAME mail
iamp4 IN CNAME mail
设置好权限和属组:
[root@dns1 named]# chmod 640 oracle.com.zone
[root@dns1 named]# chown :named oracle.com.zone
启动named服务:
[root@dns1 named]# named -u named
查看日志:
[root@dns1 named]# tail /var/log/messages

可以查询了:
[root@dns1 named]# dig -t A www.oracle.com@172.16.31.100
; <<>> DiG9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6 <<>> -t A www.oracle.com@172.16.31.100

成功了哦!
9.下面就可以进行服务启动脚本的书写了:
我们先将bind的帮助文件写进/etc/man.config进行调用:
方便named服务启动后生成pid文件:
[root@dns1 named]# chown named:named/usr/local/bind/var/run/
[root@dns1 named]# touch /var/lock/subsys/named
[root@dns1 named]# touch /etc/rc.d/init.d/named
[root@dns1 named]# chmod 755/etc/rc.d/init.d/named
[root@dns1 named]# vim /etc/rc.d/init.d/named
#!/bin/bash
# named a network name service.
# chkconfig: 345 35 75
# description: a name server
pidfile=/usr/local/bind/var/run/named/named.pid
lockfile=/var/lock/subsys/named
conffile=/etc/named/named.conf
named=/usr/local/bind/sbin/named
prog=named
[ -r /etc/rc.d/init.d/functions ] && ./etc/rc.d/init.d/functions
start() {
if [ -e $lockfile ] ; then
echo -n -e "$prog is already running.\n"
warning
echo -n -e \n
exit 0
fi
echo -n "Starting $prog:"
daemon --pidfile $pidfile $named -u named -c $conffile
tetval=$?
echo
if [[ $retval -eq 0 ]] ; then
touch $lockfile
return $retval
else
rm -f $lockfile $pidfile
return 1
fi
}
stop() {
if [ ! -e $lockfile ] ; then
echo -n "$prog is stopped."
warning
echo
exit 0
fi
echo -n "Stopping $prog:"
killproc $prog
retval=$?
echo
if [[ $retval -eq 0 ]] ; then
rm -f $lockfile $pidfile
return 0
else
echo "Can't stop $prog"
return 1
fi
}
restart() {
stop
start
}
reload() {
echo -n "Reload the $prog:"
killproc -HUP $prog
retval=$?
echo
return $retval
}
status() {
if pidof $prog &>/dev/null; then
echo -n "$prog is running."
success
echo
else
echo -n "$prog is stopped."
success
echo
fi
}
usage() {
echo "Usage:named {start|stop|status|reload|restart}"
}
case $1 in
start)
start;;
stop)
stop;;
restart)
restart;;
status)
status;;
reload)
reload;;
*)
usage
exit 1
;;
esac
有个bug,warning函数会覆盖前面的输出
我怀疑是warning函数的问题!
就不管了o(∩_∩)o 哈哈
10.最后介绍一下DNS下面的压力测试工具:queryperf
实际测试要考虑带宽哦!
[root@dns1bind-9.10.1-P1]# ls contrib
dane idn perftcpdns queryperf scripts zkt-1.1.2
dlz nslint-3.0a2 query-loc-0.4.0 README sdb
[root@dns1bind-9.10.1-P1]# cd contrib/queryperf/
[root@dns1queryperf]# ls
config.h.in configure.in Makefile.in queryperf.c utils
configure input missing README
简单编译安装:
[root@dns1 queryperf]# make
root@dns1 queryperf]# ./configure
复制命令到bin下:
[root@dns1 queryperf]# cp queryperf /bin/
开始压力测试:
queryperf [-d datafile] [-s server_addr] [-p port] [-qnum_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]
常用选项:
-d datefile:选择要解析域名集合的文件,对哪些区域进行测试
-s server_addr:指定压力测试的服务器
我们需要建立一个解析域名集合的文件:
例如:
[root@dns1 ~]#vi test.txt
www.oracle.com A
mail.oarcle.com A
oracle.com NS
oracle.com MX
pop3.oracle.com A
iamp4.oracle.com A
www.oracle.com A
mail.oarcle.com A
oracle.com NS
oracle.com MX
pop3.oracle.com A
iamp4.oracle.com A
简单测试一下哦!
[root@dns1 ~]# queryperf -d test.txt -s172.16.31.100

到这里源码安装Bind的介绍就结束了,shell脚本构建服务还是不熟练!
