通过ansible安装中间件（jdk,nginx,mysql,e
开发软件环境步骤
服务器环境
liunx实操(centOS 6.8)
CentOS6.5下安装JDK1.7+MYSQL5.5+TOMC
CentOS 7 装机
centos6.9 安装JAVA-WEB环境
jdk kafka es tomcat redis mysq
ansible实践举例-playbook安装nginx
centos安装lnmp,redis

最近部门需要线上部署产品中间件，研究了ansbile，多多百度，写了一套基于ansible-playbook的自动化部署脚本，目前主要部署jdk,nginx,mysql,etcd集群.

版本列表如下：
Centos  7.9
Ansible  2.2.0
Jdk  1.8.26
Nginx  1.20.0
Mysql 5.7.31
Etcd  3.3.25

创建yunwei用户并设置密码

[root@linux03 ~]# useradd -md /data/yunwei -s /bin/bash yunwei
[root@linux03 ~]# echo 'rl@2022'|passwd --stdin yunwei
更改用户 yunwei 的密码 。
passwd：所有的身份验证令牌已经成功更新。

上传ansible包并配置yum源(需要root用户或sudo权限)

- 安装createrepo
[root@linux03 ~]# yum install createrepo -y
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Package createrepo-0.9.9-28.el7.noarch already installed and latest version
Nothing to do
[root@linux03 ~]# cd /data/yunwei/
[root@linux03 yunwei]# ls
ansible  ansible.tar.gz  yum.sh
[root@linux03 yunwei]# sh -x yum.sh
需要采用root用户 或者 sudo权限执行-----

Complete!

上传安装包deploy.tar.gz至yunwei用户

[yunwei@linux03 ~]$ tar zxf deploy.tar.gz
[yunwei@linux03 ~]$ ls
ansible  ansible.tar.gz  deploy  deploy.tar.gz  yum.sh

将ansible.cfg内容复制至/etc/ansible/ansible.cfg

[yunwei@linux03 deploy]$ pwd
/data/yunwei/deploy
[yunwei@linux03 deploy]$ cat ansible.cfg
[defaults]
# 跳过 ssh 首次连接提示验证
host_key_checking=False
# 关闭警告提示
command_warnings=False
deprecation_warnings=False

修改hosts文件，参照如下

[yunwei@linux03 deploy]$ cat hosts
[jdk]
192.168.56.119 ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
192.168.56.117 ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
[nginx]
192.168.56.117  ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
[mysql]
192.168.56.119  ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
[etcd-cluster]
192.168.56.119  etcdname=etcd01 ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
192.168.56.116  etcdname=etcd02 ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022
192.168.56.117  etcdname=etcd03 ansible_ssh_port=22 ansible_ssh_user=cloudos ansible_ssh_pass=rl@2022

注：
1.etcd集群需要配置etcdname，用于修改配置文件，建议不动
2.安装etcd用户需要配置sudo权限

修改vars/global.yml文件

[yunwei@linux03 vars]$ cat global.yml
---
global:
  app:
    install:
      home: /data/cloudos/apps
      env: /data/cloudos/.bashrc

var:
  mysql:
    install:
      # mysql安装用户
      owner: cloudos
      # mysql组
      group: cloudos
    # mysql安装服务器ip
    host: 192.168.56.119
    # mysql端口
    port: 3306
    root:
      # mysql root用户密码
      pass: hcmp@123
    db:
      # 数据库用户
      user: hcmp
      # 数据库密码
      pass: hcmp@123
  etcd:
    etcdnodes: "etcd01=http://192.168.56.119:2380,etcd02=http://192.168.56.116:2380,etcd03=http://192.168.56.117:2380"
  nginx:
    port: 8080

注：etcdnodes的参数etcd01-etcd03与hosts的etcdname对应,需要同时修改，建议不动
