【saltstack学习笔记之十】使用sls安装nginx并管理nginx的配置文件
1.需求
使用sls安装nginx并管理nginx的配置文件，当nginx配置文件被修改时，自动更新配置文件，并重启nginx。
2.配置
1.在master端上写好nginx.sls文件
mkdir -p /srv/salt/nginx
cd /srv/salt/nginx
vim init.sls
nginx:
pkg:
- installed
service:
- running
- enable: True
- reload: True
- watch:
- pkg: nginx
- file: /etc/nginx/nginx.conf
- file: /etc/nginx/conf.d/default.conf
/etc/nginx/nginx.conf:
file.managed:
- source: salt://etc/nginx/nginx.conf
- user: root
- group: root
- mode: 644
/etc/nginx/conf.d/default.conf:
file.managed:
- source: salt://etc/nginx/conf.d/default.conf
- user: root
- group: root
- mode: 644
保存退出
2.在master端上安装nginx，方便生成nginx的配置文件(生产环境中其实是不需要安装的)
yum -y install nginx
3.创建nginx同步目录
mkdir /srv/salt/etc/nginx/conf.d -p
4.拷贝nginx的配置文件到/srv/salt/etc/nginx/目录下
cp /etc/nginx/nginx.conf /srv/salt/etc/nginx/
5.拷贝default.conf配置文件到/srv/salt/nginx/conf.d/目录下
cp /etc/nginx/conf.d/default.conf /srv/salt/etc/nginx/conf.d/
6.下发安装指令[root@Admin1-saltstack nginx]# salt '*' state.sls nginx

出现上面的信息则表示安装成功了
也可以在minion端看服务是否起来：
[root@Admin2-saltstack tmp]# /etc/init.d/nginx status
nginx (pid 3046) is running...
[root@Admin3-saltstack nginx]# /etc/init.d/nginx status
nginx (pid 2876) is running...
