5.批量安装nginx服务并定时更新配置

编写sls文件
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://config_file/nginx/nginx.conf
- user: root
- group: root
- mode: 644
/etc/nginx/conf.d/default.conf:
file.managed:
- source: salt://config_file/nginx/conf.d/default.conf
- user: root
- group: root
- mode: 644

执行sls
[root@salt-master salt]# salt 'salt-minion' state.sls sls_file.nginx

这样可以看到nginx已经安装完毕并启动
修master上的配置文件并修改端口

可以看到端口修改生效

可以看到也是生效的

首先打开pillar
pillar_roots:
base:
- /srv/pillar
创建相应目录
mkdir /srv/pillar/nginx

编写top.sls
cd /srv/pillar
必须要有top.sls
[root@salt-master pillar]# vim top.sls

base:
'salt-minion':
- nginx.nginx

编写nginx.sls
[root@salt-master pillar]# vim nginx/nginx.sls

schedule:
nginx:
function: state.sls
minutes: 1
args:
- 'nginx'

[root@salt-master pillar]# salt 'salt-minion' pillar.data
salt-minion:
----------
schedule:
----------
nginx:
----------
args:
- nginx
function:
state.sls
minutes:
1

修改配置文件
[root@salt-master pillar]# vim ../salt/config_file/nginx/conf.d/default.conf
[root@salt-master pillar]# salt 'salt-minion' saltutil.refresh_pillar
salt-minion:
True
[root@salt-master pillar]# salt 'salt-minion' cmd.run 'netstat -anutlp|grep nginx'
salt-minion:
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6535/nginx
tcp 0 0 0.0.0.0:8088 0.0.0.0:* LISTEN 6535/nginx
等待一分钟
以上需要注意的是具体应用的sls需要和实际命令一致
例如:
salt 'salt-minion' state.sls sls_file.nginx
schedule:
nginx:
function: state.sls
minutes: 1
args:
- 'nginx'
就应该为以下内容
schedule:
nginx:
function: state.sls
minutes: 1#seconds: 1
args:
- 'sls_file.nginx'
top.sls为一个路由文件
base:
'salt-minion':
- nginx.nginx
这样就会每分钟或者每秒钟执行
salt 'salt-minion' state.sls sls_file.nginx这条指令
