ansible一键部署lnvamp
lnvamp的意思是Linux(centos7.2),Nginx,varnish,Apache,MySQL,PHP。我在这个平台之上构建的discuz论坛,我写了一个roles来实现,这个脚本很不健壮幂等性不足,需要大量的判断继续完善,由于时间原因我就不继续完善了,先把草稿贴出来。同时这个脚本的复用性也不好,基本上没有使用变量,后期会慢慢改善。
架构图如下
nginx提供反向代理,安装nginx
varnish提供缓存,安装varnish
server提供页面处理,安装httpd,php,php-mysql,nfs-utils
file提供数据库和网页文件,安装mysql-server,mysql-python,nfs-utils
file的ansible内容写法
注意
因为手头没有主机了,这里file主机我使用的是centos6
mysql-python没有对应的rpm包,由于考虑幂等性的原因这里我没有使用ansible来完成,我在宿主机上执行的,这里我们只好手动编译,手动编译脚本如下
yum install python-devel mysql-devel zlib-devel openssl-devel -y yum groupinstall development tools -y wget https://pypi.python.org/packages/9a/81/924d6799494cf7fb24370335c2f782088d6ac4f79e4137d4df94cea3582c/MySQL-python-1.2.3.tar.gz tar xf MySQL-python-1.2.3.tar.gz cd MySQL-python-1.2.3 python setup.py install

调用roles的ansible内容写法
file主机的ansible调用方法
vim file.yml --- - hosts: file roles: - filesystemserver主机的ansible调用方法
vim amp.yml --- - hosts: lamp roles: - ampnginx主机的ansible调用方法
vim nginx.yml --- - hosts: nginx roles: - nginxvarnish主机的ansible调用方法
vim varnish.yml --- - hosts: varnish roles: - varnish
总结
这个实验基本上没有说原理和操作步骤,只是简单罗列文件,最后我把我编写的完整roles的下载路径过一天补上,已经上传等待审核
