基础组件
简易安装
全程Yum安装
这个没什么可说的,需要注意的是
/etc/namedmanager/config-bind.php
/etc/namedmanager/config.php
这两个文件的配置信息。
最开始应该直接用IP的方式访问,搞清楚namedmanager的机制之后再切换域名来弄。
若是测试域名记得修改
/etc/hosts
编译安装
这个就有点麻烦了,麻烦的是很多服务/配置都得自己写一遍,但是为了用最新版本还是采用这个跑了起来。
准备
编译安装BIND
此教程看到安装完成即可。(如果安装失败,那我也无能为力)
大约需要20分钟。
安装LNMP
可以自己yum安装也可以用现成的工具,本人比较懒直接用工具装的
CENTOS6.9 + PHP 5.6.32(php7也没问题) + Mysql5.6.38 (5.7没测过) + Tengine
大约需要30分钟。
下载NamedManager
以上默认完成了bind的编译,LNMP环境的搭建,namedmanager的下载(zip解压到/data/wwwroot/www)
配置namedmanager
前提说明
#配置文件信息
1.named 编译目录
/usr/local/bind #所以 有些服务的位置就在 /usr/local/bind/sbin 后面会用
2.named 配置文件目录 / 额外参数目录
/etc/named
/var/named
3.namedmanager 目录
/data/wwwroot/www
4.namedmanager 网站修改后会同步到数据库及 /etc/named.namedmanager.conf (自动修改 此处仅说明)
5.同步机制 每分钟自动运行
/etc/cron.d/namedmanager-bind
6.namedmanager 数据库连接及配置信息 /etc/namedmanager/config.php
/etc/namedmanager/config-bind.php
直接贴配置

$config["bind"]["verify_config"] = "/usr/local/bind/sbin/named-checkconf"; // Used to verify generated NamedManager configuration
注意1 service start
编译安装的没有/etc/init.d/named服务 主要修改 /usr/local/bind/sbin 相关的位置 若编译位置在 /usr/local/bind 的直接可用

注意2 安装namedmanager相关
https://github.com/jethrocarr/namedmanager/wiki/Installation-Git
因为我们使用的是 /data/wwwroot/www 存放这个网页服务
#导入数据库
cd /data/wwwroot/www
mysql -u root -p < sql/version_LATESTDATE_install.sql
#添加数据库用户及密码(这个就不贴了 只要新增的用户能够管理上一步操作的数据库即可)
#设置配置文件
mkdir /etc/namedmanager/
#依然在 /data/wwwroot/www 目录
cp htdocs/include/sample-config.php /etc/namedmanager/config.php
#这一步是为了方便管理 只需要修改/etc/namedmanager/config.php 内容即可保证web服务运行,具体内容上面有贴入
ln -s /etc/namedmanager/config.php /data/wwwroot/www/htdocs/include/config-settings.php
#以下是创建config-bind.php 和 上面的config.php 不是一回事 切记 切记!!!
cp bind/include/sample-config.php /etc/namedmanager/config-bind.php
ln -s /etc/namedmanager/config-bind.php /data/wwwroot/www/bind/include/config-settings.php
注意3 定时脚本及任务
在原来的官方文档中定时脚本是和[注意2]一起出现的,经过本人的安装经历,决定单独放出来
#依然在 /data/wwwroot/www
cp resources/namedmanager_logpush.rcsysinit /etc/init.d/namedmanager_logpush
cp resources/namedmanager-www.cron /etc/cron.d/namedmanager-www
cp resources/namedmanager-bind.cron /etc/cron.d/namedmanager-bind
#以上需要修改对应的具体内容,主要是改路径
mkdir /var/log/namedmanager
chown www:www /var/log/namedmanager
#创建日志路径及权限
https://github.com/jethrocarr/namedmanager/wiki/Installation-Integration-Bind
官方文档提过
php -q /usr/share/namedmanager/bind/namedmanager_bind_configwriter.php
改为
php -q /data/wwwroot/www/bind/namedmanager_bind_configwriter.php
#这也就是定时任务中会用到的语句,记得修改定时任务中的内容
总结
BIND安装容易,但是NamedManager去管理不容易。
过程中出现了几点麻烦单独再提出以下:
1.WEB程序的的脚本路径问题;
2.PHP的函数权限问题,需要打开exec,fopen等;
3.PHP函数的max_vars的问题 因为子域名很多默认是1000,超过1000就要去修改(搜索ini的max关键字);
4.修改后自动同步并重启服务的问题,主要观察php日志或/var/log/message的相关日志(本人出现这个问题是因为config-bind.php没有指定rndc的路径即$config["bind"]["reload"]);
5.发现无法同步是通过查看定时任务日志找到的原因,日志在 /var/log/cron。
