Automatic deployment of nginx source code through saltstack

Experimental topology

Node name	IP	function
server1	172.25.21.1	salt-server
server3	172.25.21.3	Salt minion, nginx server

The basic configuration of each node will not be described in detail. See my blog for details Saltstack automation management tool

The configuration on the server side is as follows:

In the file roots directory, create the directory and sls file

 [root@server1 salt]# mkdir nginx   # Create nginx directory
 [root@server1 salt]# cd nginx/     # Entry directory

Edit install build script

 [root@server1 nginx]# vim install.sls
 //Edit as follows:
 nginx_install:            # Dependency installation required by nginx
   pkg.installed:
     - pkgs:
       - gcc-c++
       - openssl-devel
       - pcre-devel
       - zlib-devel

   file.managed:            # File management, source package push
     - name: /root/nginx-1.14.0.tar.gz
     - source: salt://nginx/files/nginx-1.14.0.tar.gz

   cmd.run:                 # Execute the command. Decompress and compile
     - name: cd /root/ && tar zxf nginx-1.14.0.tar.gz && cd nginx-1.14.0 && sed -i.bak 's/#define NGINX_VER          "nginx\/" NGINX_VERSION/#define NGINX_VER          "nginx"/g' src/core/nginx.h && sed -i.bak 's/CFLAGS="$CFLAGS -g"/#CFLAGS="$CFLAGS -g"/g' auto/cc/gcc  && ./configure --prefix=/usr/local/nginx --with-file-aio --with-threads --with-http_ssl_module --with-http_stub_status_module &> /dev/null && make &>/dev/null && make install &>/dev/null
     - creates: /usr/local/nginx

Edit complete, push to minion

 [root@server1 salt]# salt server3 state.sls nginx.install

The results are as follows:


Push succeeded, nginx compilation and installation on server3 completed
Can be viewed in server3

Edit user script

Create a script under / srv/salt for creating service users

 [root@server1 salt]# mkdir users 
 [root@server1 salt]# cd users
 [root@server1 users]# vim nginx.sls
 //The editing contents are as follows:
 nginx-group:
   group.present:         # Set up user groups
     - name: nginx        # Group name
     - gid: 800           # Group ID

 nginx-user:              # Build user
   user.present:          
     - name: nginx        # Username
     - uid: 800           # Specify user ID
     - gid: 800           # Specified group ID
     - shell: /sbin/nologin    # Specify Shell type
     - createhome: False  # Not created. User home directory
     - home: /usr/local/nginx  # Specify user home directory

~                       

After editing, push to server3 (green indicates successful execution, blue indicates modified content)

 [root@server1 users]# salt server3 state.sls users.nginx

View on server3

Write scripts related to service startup

 [root@server1 salt]# vim nginx/service.sls 
 include:         # Other scripts included
   - nginx.install
   - users.nginx
   - pkgs.make

 /usr/local/nginx/conf/nginx.conf:       # Profile of the service
   file.managed:
     - source: salt://nginx/files/nginx.conf


 nginx-service:                  # Information about service startup
   file.managed:
     - name: /etc/init.d/nginx    # Start your steps
     - source: salt://nginx/files/nginx
     - mode: 755
   service.running:               # running method of service module
     - name: nginx
     - reload: True
     - watch:
       - file: /usr/local/nginx/conf/nginx.conf

Push

 [root@server1 salt]# salt server3 nginx.service

After push, view on server3:
