环境： Centos 5.4 使用软件： wget http://mydns.bboy.net/download/mydns-1.1.0.tar.gz wget http://soft.vpser.net/datebase/mysql/mysql-5.1.54.tar.gz 安装前准备： yum -y install gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel vim-minimal nano fonts-chinese gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip 一、安装mysql数据库 tar zxvf mysql-5.1.54.tar.gz cd mysql-5.1.54 ./configure --prefix=/usr/local/mysql --with-extra-charsets=all --enable-thread-safe-client --enable-assembler --with-charset=utf8 --with-extra-charsets=all --with- big-tables --with-readline --with-ssl --with-embedded-server --enable-thread-safe-client --enable-local-infileser make make install groupadd mysql useradd -s /sbin/nologin -M -g mysql mysql cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf sed -i 's/skip-locking/skip-external-locking/g' /etc/my.cnf /usr/local/mysql/bin/mysql_install_db --user=mysql chown -R mysql /usr/local/mysql/var chgrp -R mysql /usr/local/mysql/. cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql chmod 755 /etc/init.d/mysql vim /etc/ld.so.conf.d/mysql.conf添加如下： /usr/local/mysql/lib/mysql /usr/local/lib ldconfig ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql ln -s /usr/local/mysql/include/mysql /usr/include/mysql /etc/init.d/mysql start ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql ln -s /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump ln -s /usr/local/mysql/bin/myisamchk /usr/bin/myisamchk /usr/local/mysql/bin/mysqladmin -u root password 123456 设置密码 二、安装mydns: tar zxvf mydns-1.1.0.tar.gz ./configure --prefix=/usr/local/mydns --with-mysql-lib=/usr/local/mysql/lib/mysql/ --with-mysql-include=/usr/local/mysql/include/mysql/ make && make install /usr/local/mysql/bin/mysqladmin -uroot -p create mydns 创建dns数据库 mysql>insert into mysql.user (host,user,password) values ('localhost','mydns',password('mydns')); //建立用户mydns，密码mydns mysq>flush privileges; //重载MySQL授权表 mysql>grant all on mydns.* to mydns@'localhost' identified by 'mydns'; 把数据mydns授权于用户mydns 生成主配置文件： /usr/local/mydns/sbin/mydns --dump-config > /etc/mydns.conf 三、配置mydns: 修改mydns.conf如下： # DATABASE INFORMATION db-host = localhost # SQL server hostname db-user = mydns # SQL server username db-password = mydns # SQL server password database = mydns # MyDNS database name # GENERAL OPTIONS user = mydns # Run with the permissions of this user group = mydns # Run with the permissions of this group listen = 172.16.6.200 # Listen on these addresses ('*' for all) no-listen = # Do not listen on these addresses # CACHE OPTIONS zone-cache-size = 1024 # Maximum number of elements stored in the zone cache zone-cache-expire = 60 # Number of seconds after which cached zones expires reply-cache-size = 1024 # Maximum number of elements stored in the reply cache reply-cache-expire = 30 # Number of seconds after which cached replies expire # ESOTERICA log = LOG_DAEMON # Facility to use for program output (LOG_*/stdout/stderr) pidfile = /var/run/mydns.pid # Path to PID file timeout = 120 # Number of seconds after which queries time out multicpu = 1 # Number of CPUs installed on your system recursive = 8.8.8.8 # Location of recursive resolver把解析不了的转发到8.8.8 recursive-timeout = # Number of seconds before first retry recursive-retries = # Number of retries before abandoning recursion recursive-algorithm = # Recursion retry algorithm one of: linear, exponential, progressive allow-axfr = yes # Should AXFR be enabled?
