bind智能DNS + bindUI管理系统（postgresql + bind dlz）
# 软件环境：
* Centos 7.6
* bind-9.14.1.tar.gz
* postgresql 11
* python 3.7
* django 2.2.1
QPS：单节点1590 qps
# 目前测试性能最高的方案
* bind-9.12.4/bind-9.12.1、postgresql 11、Centos 7.6，4核心8G的ESXi虚拟机，开4线程，单节点查询性能可达68842 qps
zone数据使用文件配置加载到内存方式（即不使用数据库）的测试性能可达：80514 qps
## 测试其他说明
bind-9.12.4、mysql开多线程则奇慢无比
bind-9.13.3到bind-9.15.0都只有单线程，即使启动参数配置多线程，实际运行也是单线程，经过测试，这些版本与mysql结果性能会比postgresql高一些，mysql性能2300 qps左右，postgresql性能1600 qps，基本范围1400-2400 qps
从bind-9.13.3及之后的版本不支持 --enable-threads 配置参数，即多线程的支持，bind-9.13.2还支持
# 安装基本包
yum install -y bind-utils traceroute wget man sudo ntp ntpdate screen patch make gcc gcc-c++ flex bison zip unzip ftp net-tools --skip-broken
关联动态库
# vi /etc/ld.so.conf 添加如下内容
include /etc/ld.so.conf.d/*.conf
/usr/local/lib
/usr/local/lib64
/lib
/lib64
/usr/lib
/usr/lib64
编辑完ld.so.conf,执行
ldconfig
使动态库生效
# 安装postgresql
参考地址：https://www.postgresql.org/download/linux/redhat/
yum -y install https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-redhat11-11-2.noarch.rpm
yum -y install postgresql11
yum -y install postgresql11-server
yum -y install postgresql11-libs
yum -y install postgresql11-devel
/usr/pgsql-11/bin/postgresql-11-setup initdb
systemctl enable postgresql-11
## 添加环境变量
把/usr/pgsql-11/bin加入到 /etc/profile系统环境变量里
如：
## PATH export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:$JAVA_HOME/bin:/usr/pgsql-11/bin
. /etc/profile
## postgresql设置
/var/lib/pgsql/11/data/postgresql.conf
listen_addresses = '*' port = 5432 max_connections = 5120
tail -n 20 /var/lib/pgsql/11/data/pg_hba.conf
规则从上往下匹配，匹配到一条后就停止往下匹配了
# TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all peer # IPv4 local connections: ## host all all 127.0.0.1/32 identhost all all 127.0.0.1/32 md5 host all all 0.0.0.0/0 md5# IPv6 local connections: host all all ::1/128 ident # Allow replication connections from localhost, by a user with the # replication privilege. #local replication all peer #host replication all 127.0.0.1/32 ident #host replication all ::1/128 ident
## 启动postgresql
systemctl start postgresql-11
## 创建用户、数据库
su postgres
psql
create user bind_ui_wr with encrypted password 'ww123456'; # encrypted 表示用加密方式保存密码，如果不指定，则是根据配置文件中的password_encryption参数决定
create database bind_ui owner bind_ui_wr ENCODING=utf8;
## 创建只读用户
CREATE USER bind_ui_r WITH ENCRYPTED PASSWORD 'rr123456';
alter user bind_ui_r set default_transaction_read_only=on; # 设置默认事务只读
GRANT CONNECT ON DATABASE bind_ui to bind_ui_r; # 赋予用户连接数据库bind_ui的权限
\c bind_ui # 切换到指定库bind_ui
GRANT USAGE ON SCHEMA public to bind_ui_r; # 把当前库现有的所有在public这个schema下的表的使用权限赋给用户
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON TABLES TO bind_ui_r; # 默认把当前库之后新建在public这个schema下的表的使用权限赋给bind_ui_r
GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO bind_ui_r; # 赋予用户bind_ui_r所有public下的序列的查看权
GRANT SELECT ON ALL TABLES IN SCHEMA public TO bind_ui_r; # 赋予用户bind_ui_r所有public下的表的select权
## 删除只读用户方法
revoke USAGE ON SCHEMA public from bind_ui_r; # 回收schema的usage权限
revoke SELECT ON ALL TABLES IN SCHEMA public from bind_ui_r; # 回收public下所有表的查询权限
revoke SELECT ON ALL SEQUENCES IN SCHEMA public from bind_ui_r; # 回收public下所有序列的查询权限
ALTER DEFAULT PRIVILEGES IN SCHEMA public revoke SELECT ON TABLES from bind_ui_r; # 回收默认权限
revoke CONNECT ON DATABASE foo from bind_ui_r; # 关闭数据库连接权限
alter user bind_ui_r set default_transaction_read_only=off; # 关闭默认只读事务设置
\ddp # 查看权限是否为空了
drop user bind_ui_r; # 删除用户
## 测试连接
psql -h 127.0.0.1 -p 5432 -U bind_ui_wr -d bind_ui

注意： /usr/local/bind/sbin/named -n 1 线程数
经测试，bind-9.13、bind-9.14已经与线程数量无关，均为单线程了。设置-n 4与-n 1性能都一样
bind-9.12.4、postgresql 11开多线程，性能很高

view配置：
存放目录：/etc/named/conf.d
这里连接数据库的账号只需要只读权限就可以了
cat cn_yd.conf # match-clients要与定义的acl匹配
view "cn_yd" {
match-clients { cn_yd; };
dlz "Postgres zone" {
database "postgres 2
{host=127.0.0.1 dbname=bind_ui port=5432 user=bind_ui_r password=rr123456}
{select zone_name from \"DnsRecord_zonetag\" where zone_name = '$zone$'}
{select ttl, type, mx_priority,
case when lower(type)='txt' then
concat('\"', data, '\"')
when lower(type) = 'soa' then

end

and (\"DnsRecord_record\".resolution_line = '103' or \"DnsRecord_record\".resolution_line = '0')

注意：这里
DnsRecord_record.resolution_line 的值要与 bindUI定义值相同，以区别不同的解析线路
其他类似

# 安装python 3.7
cd /usr/loca/src; wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
tar -Jxvf Python-3.7.3.tar.xz; cd Python-3.7.3
./configure --prefix=/usr/local/python_3.7.3; make; make install
可以把 /usr/local/python_3.7.3/bin 添加系统环境变量，这样使用更简单
/usr/local/python_3.7.3/bin/pip install --upgrade pip
/usr/local/python_3.7.3/bin/pip install virtualenv
## 更换国内pipy源，安装python扩展更快
参考：https://www.cnblogs.com/meelo/p/4636340.html
cat ~/.pip/pip.conf
[global] index-url = https://mirrors.aliyun.com/pypi/simple/ [install] trusted-host = mirrors.aliyun.com
## 创建用于运行BindUI项目的python虚拟环境
mkdir -p /data/pyvenv/
/usr/local/python_3.7.3/bin/pyvenv /data/pyvenv/BindUI
要进虚拟python环境操作方法
. /data/pyvenv/BindUI/bin/activate
退出虚拟环境
deactivate
# 部署BindUI项目
mkdir -p /data/webroot
cd /data/webroot
yum -y install git
git clone https://github.com/cucker0/BindUI.git
rm -rf /data/webroot/BindUI/.git # 为网站安全
## 设置配置信息，设置连接数据库信息
/data/webroot/BindUI/bindUI/settings.py
注释下面这两行
# import pymysql # pymysql.install_as_MySQLdb()
这里的账号需要有写读权限
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'bind_ui',
'USER': 'bind_ui_wr',
'PASSWORD': 'ww123456',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
## 安装依赖组件
cd /data/webroot/BindUI
. /data/pyvenv/BindUI/bin/activate
pip install --upgrade pip
pip install django Pillow pymysql IPy xlrd xlwt psycopg2
## 初始化数据库
python manage.py migrate python manage.py makemigrations python manage.py migrate
## 创建超级用户
python manage.py createsuperuser
## 运行django
python manage.py runserver 0.0.0.0:8080
此时可以通过下面的URL访问BindUI控制台
http://服务器IP:8080
使用上面的登记登录
* 登录
* 首页
* 添加域名
* 设置NS主机，可设置多个
* 添加起始授权主机、NS主机相应的记录
NS主机设置了多个就需要建立多个，起始授权主机只有一个
建一个反向解析域
同样也需要设置NS主机
建立PTR记录，与NS主机记录对应
此时就能建其他记录了
## 给bind_ui_r用户添加相应表的只读权限
上面授权时，因为下面这些表还没有创建，所以是没有授到权的，需要重新执行一次。
su postgres psql \c bind_ui GRANT SELECT ON "DnsRecord_record" TO bind_ui_r; GRANT SELECT ON "DnsRecord_zonetag" TO bind_ui_r;
## 启动bind服务
systemctl start named
bind启动调试模式方法
/usr/local/bind/sbin/named -n 1 -u named -c /usr/local/bind/etc/named.conf -d 4 -g
此时就可以解析了
# Django Nginx+ uWSGI 运行django项目
前面运行的django 在bash控制上，现在以守护进程方式运行，参考https://www.cnblogs.com/linkenpark/p/6560787.html
## 安装uwsgi
/usr/local/python_3.7.3/bin/pip install uwsgi
id uwsgi
uid=1000(uwsgi) gid=1000(uwsgi) groups=1000(uwsgi)
/usr/local/python_3.7.3/bin/uwsgi --http 0.0.0.0:8000 -H /data/pyvenv/BindUI --chdir /data/webroot/BindUI/ --wsgi-file bindUI/wsgi.py
这时在浏览器上能看到除了样式外的页面
退出uwsgi
## 配置uwsgi
mkdir /etc/uwsgi
vi /etc/uwsgi/uwsgi9090.ini

chown -R uwsgi:uwsgi /data/webroot/BindUI//upload/user_image # 上传用户头像的目录可写，其他目录只需要只读权限即可。
## 设置uwsgi自动启动脚本

## 更新项目代码
当python项目代码有更新时，要让其生效，重载或重启 uwsgi服务即可
systemctl reload uwsgi

## django admin静态文件加载不了问题
在/data/webroot/BindUI/bindUI/settings.py 最后添加下面设置
STATIC_ROOT = os.path.join(BASE_DIR, "static")
STATICFILES_FINDERS = (
"django.contrib.staticfiles.finders.FileSystemFinder",
"django.contrib.staticfiles.finders.AppDirectoriesFinder"
)
cd /data/webroot/BindUI
. /data/pyvenv/BindUI/bin/activate
python manage.py collectstatic #生产静态问题，询问覆盖时，输入yes，这时生成了这个目录 /data/webroot/BindUI/static/admin
再把上面添加的配置删除或注释
deactivate
最终访问效果：
