SaltStack实战—部署LNMT

62 阅读 0 评论
我是靠谱客的博主 高高猎豹，最近开发中收集的这篇文章主要介绍SaltStack实战—部署LNMT，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

环境：

角色主机名IP应用
masternode01172.16.78.125salt-master
salt-ssh
salt-minion
minionnginx172.16.78.128nginx
salt-minion
minionmysql172.16.78.129mysql
salt-minion
miniontomcat172.16.78.130tomcat
salt_minion

步骤：

1. 使用salt-ssh进行批量安装salt-minion

关于如何使用批量安装可以参考 SaltStack之salt-ssh

[root@node01 ~]# vim /etc/salt/roster
node02:
  host: 172.16.78.128
  user: root
  passwd: 123
node03:
  host: 172.16.78.129
  user: root
  passwd: 123
node04:
  host: 172.16.78.130
  user: root
  passwd: 123

[root@node01 ~]# salt-ssh '*' state.highstate
...省略状态执行返回值
Changes:   
              ----------
              salt-minion:
                  True

Summary for node04
------------
Succeeded: 5 (changed=5)
Failed:    0
------------
Total states run:     5
Total run time:  26.573 s

2. 接受minion的证书，并使用salt命令测试连通性

[root@node01 ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
mysql
nginx
tomcat
[root@node01 ~]# salt-key -yA
[root@node01 ~]# salt-key -L
Accepted Keys:
mysql
nginx
tomcat
Denied Keys:
Unaccepted Keys:
Rejected Keys:

[root@node01 ~]# salt '*' test.ping
tomcat:
    True
mysql:
    True
nginx:
    True

3. 创建环境目录

[root@node01 ~]# mkdir -p /srv/salt/base
[root@node01 ~]# cd /srv/salt/base/
[root@node01 base]# mkdir -p lnmt/{nginx,mysql,tomcat,repo}
[root@node01 base]# cd lnmt/
[root@node01 lnmt]# ls
mysql  nginx  tomcat  repo

4. 配置repo状态文件

[root@node01 lnmt]# cd repo
[root@node01 repo]# mkdir file
[root@node01 repo]# cd file/
[root@node01 file]# wget https://mirrors.aliyun.com/repo/Centos-7.repo
[root@node01 file]# sed -i 's/$releasever/7/g' Centos-7.repo 
[root@node01 file]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' Centos-7.repo
[root@node01 file]# wget http://mirrors.aliyun.com/repo/epel-7.repo

[root@node01 file]# cd ..
[root@node01 repo]# vim repo.sls
/etc/yum.repos.d/Centos-7.repo:
  file.managed:
    - source: salt://lnmt/repo/file/Centos-7.repo

/etc/yum.repos.d/epel-7.repo:
  file.managed:
    - source: salt://lnmt/repo/file/epel-7.repo
  cmd.run:
    - name: yum clean all && yum makecache && yum -y groups mark install 'Development Tools'
  pkg.installed:
    - pkgs:
      - pcre-devel
      - openssl
      - openssl-devel
      - gd-devel
      - gcc
      - gcc-c++
      - wget

5. 配置nginx状态文件

[root@node01 lnmt]# cd nginx/
[root@node01 nginx]# mkdir file
[root@node01 nginx]# cd file
[root@node01 file]# wget http://nginx.org/download/nginx-1.18.0.tar.gz
[root@node01 file]# vim install.sh

  cmd.run:
    - name: cd /usr/src && tar xf mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
    - unless: test -d /usr/local/mysql-5.7.30-linux-glibc2.12-x86_64

/usr/local/mysql:
  file.symlink:

-------------------------------------------------------------------
[root@node01 mysql]# vim server.sls
mysql-server:
  service.running:
    - name: mysqld
    - enable: True

7. 配置tomcat状态文件

[root@node01 lnmt]# cd tomcat/
[root@node01 tomcat]# mkdir file
[root@node01 tomcat]# cd file/
[root@node01 file]# wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz

[root@node01 tomcat]# cat install.sls
include:

install_java_package:
  pkg.installed:
    - pkgs:
      - java-1.8.0-openjdk
      - java-1.8.0-openjdk-devel

/usr/src/apache-tomcat-9.0.37.tar.gz:
  file.managed:
    - source: salt://lnmt/tomcat/file/apache-tomcat-9.0.37.tar.gz
  cmd.run:
    - name: cd /usr/src && tar xf apache-tomcat-9.0.37.tar.gz -C /usr/local/
    - unless: test -d /usr/local/apache-tomcat-9.0.37 

/usr/local/tomcat:
  file.symlink:
    - target: /usr/local/apache-tomcat-9.0.37
-------------------------------------------------------------------
[root@node01 tomcat]# cat server.sls 
tomcat_server:
  cmd.run:
    - name: /usr/local/tomcat/bin/catalina.sh start

8. 配置nginx与tomcat交互

[root@node01 nginx]# cat file/nginx.conf
...
#access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://172.16.78.130:8080;   //修改此行
        }
...

[root@node01 nginx]# cat config.sls 
/usr/local/nginx/conf/nginx.conf:
  file.managed:
    - source: salt://lnmt/nginx/file/nginx.conf

nginx:
  service.running:
    - reload: True
    - watch:
      - file: /usr/local/nginx/conf/nginx.conf

9. 配置高级状态

[root@node01 base]# vim top.sls
base:
  'nginx':
    - lnmt.nginx.install
    - lnmt.nginx.server
    - lnmt.nginx.config
  'mysql':
    - lnmt.mysql.install
    - lnmt.mysql.server
  'tomcat':
    - lnmt.tomcat.install
    - lnmt.tomcat.server

10. 整个base环境结构

[root@node01 base]# tree
.
└── lnmt
    ├── mysql
    │   ├── file
    │   │   ├── my.cnf
    │   │   ├── mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz
    │   │   └── mysql.service
    │   ├── install.sls
    │   └── server.sls
    ├── nginx
    │   ├── config.sls
    │   ├── file
    │   │   ├── install.sh
    │   │   ├── nginx-1.18.0.tar.gz
    │   │   ├── nginx.conf
    │   │   └── nginx.service
    │   ├── install.sls
    │   └── server.sls
    ├── repo
    │   ├── file
    │   │   ├── Centos-7.repo
    │   │   └── epel-7.repo
    │   └── repo.sls
    └── tomcat
        ├── file
        │   └── apache-tomcat-9.0.37.tar.gz
        ├── install.sls
        └── server.sls

9 directories, 18 files

11. 执行高级状态

[root@node01 base]# salt '*' state.highstate
...省略状态返回值

12. 访问验证
在这里插入图片描述
访问nginx服务器IP，成功跳转至tomcat页面了
