puppet 横向扩展(一)
目录
概述
横向扩展实验之一 – 扩展puppet master 的个数.
实验环境
master 和 node 都是 debian 7.7 i686 系统
2个 puppet master 在一台机器上, 都是 apache 虚拟主机
实验步骤
创建puppetmaster的rack环境
cd /usr/share/puppet/rack
mkdir -p puppetmasterd_18140/{public,tmp}
cp puppetmasterd/config.ru puppetmasterd_18140/
chown puppet puppetmasterd_18140/config.ru
mkdir -p puppetmasterd_18141/{public,tmp}
cp puppetmasterd/config.ru puppetmasterd_18141/
chown puppet puppetmasterd_18141/config.ru
配置文件设置
- passenger.conf : passenger 配置信息
放在 /etc/apache2/mods-available 中， 并在 /etc/apache2/mods-enabled中建立软连接 - puppetmaster_proxy.conf
关闭 SSL， 重新请求头部， 为后端进程做负载均衡，放在 /etc/apache2/site-available 中， 并在 /etc/apache2/site-enabled中建立软连接 - puppetmaster_worker_1.conf
虚拟主机1， 指向处理puppet请求的Rac目录，放在 /etc/apache2/site-available 中， 并在 /etc/apache2/site-enabled中建立软连接 - puppetmaster_worker_2.conf
虚拟主机2， 指向处理puppet请求的Rac目录，放在 /etc/apache2/site-available 中， 并在 /etc/apache2/site-enabled中建立软连接
各个配置文件的详细内容如下:
$ cat passenger.conf
<IfModule mod_passenger.c>
PassengerRoot /usr
PassengerRuby /usr/bin/ruby
# And the passenger performance tuning settings
PassengerHighPerformance On
# Set this to about 1.5 times the number of CPU cores in your master:
PassengerMaxPoolSize 2
# Recycle master processes after they service 1000 requests
PassengerMaxRequests 1000
# Stop processes if they sit idle for 10 minutes
PassengerPoolIdleTime 600
</IfModule>
$ cat puppetmaster_proxy.conf
# Available back-end worker virtual hosts
# NOTE the use of cleartext unencrypted HTTP.
<Proxy balancer://puppetmaster>

补充说明
apache默认没有加载 proxy 和 proxy_balancer 和 proxy_http 模块，需要补上
cd /etc/apache2/mods-enabled
ln -s ../mods-available/proxy.conf proxy.conf
ln -s ../mods-available/proxy.load proxy.load
ln -s ../mods-available/proxy_balancer.conf proxy_balancer.conf
ln -s ../mods-available/proxy_balancer.load proxy_balancer.load
ln -s ../mods-available/proxy_http.load proxy_http.load # 没有这个模块， agent 会有 503错误
cd /etc/apache2/sites-enabled
ln -s ../sites-available/puppetmaster_proxy.conf puppetmaster_proxy
ln -s ../sites-available/puppetmaster_worker_1.conf puppetmaster_worker_1
ln -s ../sites-available/puppetmaster_worker_2.conf puppetmaster_worker_2
默认的 8140 端口关闭
rm /etc/apache2/sites-enabled/puppetmaster
service apache2 restart
配置完成后如果有类似如下 403 权限不足的错误
Warning: Unable to fetch my node definition, but the agent run will continue:
Warning: Error 403 on SERVER: Forbidden request: localhost(127.0.0.1) access to /certificate_revocation_list/ca [find] at :119
那么, 将 master-1 上的 /etc/puppet/puppet.conf 文件中 [master] 下 如下2行注释掉。（估计SSL由代理服务器来完成）
#ssl_client_header = SSL_CLIENT_S_DN
#ssl_client_verify_header = SSL_CLIENT_VERIFY
测试配置结果
默认的负载均衡
# puppet master 上执行
root@master-1:/var/log/apache2# service apache2 restart
# 开始时, 负载均衡的log都是空的
root@master-1:/var/log/apache2# ll /var/log/apache2/

从上面的log可以看出 agent 上执行的 puppet agent -t 一共访问了 5 次 master.
其中3次由 worker_1 处理了, 2次由 worker_2 处理了. <== 这就是负载均衡的效果
负载均衡情况下, 一台 puppet master 挂了的情况
# master 上执行, 清空log, 删除 puppetmaster_worker_1 的配置, 重启apache2 服务
root@master-1:~# rm /var/log/apache2/* -rf

从上面的log可以看出, 没有生成 worker_1 的log, 全部处理都是由 worker_2 完成的. agent 也没有出错.
