多節點nginx安裝配置

定義多節點

cd /srv/salt

vim top.sls

base:
  ‘server4.lalala.com‘:
    - nginx.install
  ‘server1.lalala.com‘:
    - nginx.install

把要共享的文件放在指定目錄

[[email protected] files]# pwd

/srv/salt/nginx/files

[[email protected] files]# ls n

ginx-1.10.1.tar.gz

vim /srv/salt/nginx/install.sls

nginx-install:
  pkg.installed:    #安裝包的依賴性
 
    - pkgs:
      - gcc
      - pcre-devel
      - openssl-devel
  file.managed:
    - name: /mnt/nginx-1.10.1.tar.gz      #安裝在客戶端的位置
    - source: salt://nginx/files/nginx-1.10.1.tar.gz #服務器共享文件的位置
  cmd.run:
    - name: cd /mnt;tar zxf nginx-1.10.1.tar.gz;cd nginx-1.10.1;./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-threads &> /dev/null && make &> /dev/null && make install &> /dev/null
 

高級狀態的執行(多節點)

[[email protected] nginx]# salt ‘‘ state.highstate test=True

[[email protected] nginx]# salt ‘‘ state.highstate

vim install.sls

include:
  - pkg.install
  - user.nginx

nginx-source:
  file.managed:
    - name: /mnt/nginx-1.10.1.tar.gz
    - source: salt://nginx/files/nginx-1.10.1.tar.gz

nginx-install:
 
  cmd.run:
    - name: cd /mnt;tar zxf nginx-1.10.1.tar.gz;cd nginx-1.10.1;./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-threads &> /dev/null && make &> /dev/null && make install &> /dev/null
    - creates: /usr/local/nginx
    - require:
      - pkg: pkg-install
      - file: nginx-source
      - user: nginx-user

vim service.sls

 include: 
   - nginx.install

nginx-config:
  file.managed:
    - name: /usr/local/nginx/conf/nginx.conf
    - source: salt://nginx/files/nginx.conf

nginx-init:
  file.managed:
    - name: /etc/init.d/nginx
    - source: salt://nginx/files/nginx
    - mode: 755
  cmd.run:
    - name: chkconfig --add nginx
    - unless: chkconfig --list nginx #如果不存在，就執行以上語句
    - require:
      - file: nginx-init
  service.running:
    - name: nginx
    - enable: True
    - reload: True
    - watch:
      - file: nginx-config

需要推給客戶端信息

[[email protected] files]# ls nginx nginx-1.10.1.tar.gz nginx.conf [[email protected] files]#

編輯啟動腳本

vim nginx

 36 nginx=${NGINX-/usr/local/nginx/sbin/nginx}
 37 prog=`/bin/basename $nginx`
 38 conffile=${CONFFILE-/usr/local/nginx/conf/nginx.conf}
 39 lockfile=${LOCKFILE-/var/lock/subsys/nginx}
 40 pidfile=${PIDFILE-/usr/local/nginx/logs/nginx.pid}

編輯主配置文件

vim nginx.conf

user  nginx nginx;
listen       8000;

檢測

[[email protected] files]# salt ‘*‘ state.sls nginx.service

可以看到,1,3主機 的8000端口,被打開被nginx占用

[[email protected] files]# lsof -i :4505 -n
COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
salt-mast 2339 root   16u  IPv4  14683      0t0  TCP *:4505 (LISTEN)
salt-mast 2339 root   18u  IPv4  53804      0t0  TCP 172.25.88.3:4505->172.25.88.1:49253 (ESTABLISHED)
salt-mast 2339 root   19u  IPv4  37637      0t0  TCP 172.25.88.3:4505->172.25.88.4:59132 (ESTABLISHED)

消息隊列，長連接方式，一直保持established，不用請求和回復，所以快
