这些编译安装的东西没必要深究,没任何意义.简单方便为好.

1. bind物理机安装

  • 需求: 找一个有api的dns.可以直接增加mysql记录不用重启dns即可动态更新,于是动手搞一套mysqlbackend+bind.

    后来发现有 powerdns dj-dns也可以实现这些功能,没必要自己搞.

  • 思路: 先搞清楚物理机怎么编译bind-->容器化mysql--> 容器化mysql+supervisor-->容器化mysql+supervisor+bind

  • 目前最新的bind集合mysql不需要改bind源代码了,改起来很烦的.

  • bind和mysql本来不想安装在一台机器上,无奈编译bind需要依赖mysql的lib库(期间我尝试按照mysql-devel还是没能解决),这里已经解决了. 我用debian:jessie为基础

apt-get install -y g++ libboost-all-dev libtool make pkg-config libmysqlclient-dev libssl-dev

然后编译安装bind9.11就可以了.见文末

  • 1.1二进制安装 mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz
yum -y install perl-devel

tar -xf mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

ln -s mysql-5.6.30-linux-glibc2.5-x86_64 /usr/local/mysql

useradd mysql -s /sbin/nologin -M

chown -R mysql:mysql /usr/local/mysql/

cd /usr/local/mysql/support-files/

\cp my-default.cnf /etc/my.cnf       ## 这个配置文件可以用第二部分my.conf改了字符集

\cp mysql.server /etc/init.d/mysqld   ## 这样/etc/init.d/mysqld start 就可以启动了

/usr/local/mysql/bin/mysqladmin -u root password '123456'

vi /etc/profile

export PATH=$PATH:/usr/local/mysql/bin

# 初始化-物理机这样操作,如果在容器部分,则可以将初始化好的/data目录替换mysql二进制包里的data,之后就不需要构建镜像时候初始化了.

/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

# 启动

/usr/local/mysql/bin/mysqld_safe --user=mysql   #前台启动

/usr/local/mysql/bin/mysqld_safe --user=mysql &
  • 1.2编译安装bind-9.11.2.tar.gz

一定要编译安装,加上with-dlz-mysql, yum安装默认是不支持mysql backend的.

echo "/usr/local/mysql/lib" >>/etc/ld.so.conf \

ldconfig

yum install -y perl-devel openssl-devel

cd /usr/local/src/

tar xf  bind-9.11.2.tar.gz
