基于ansible自动部署java环境，redis5.0.5集群，elasticsearch6.3.1集群；完整的安装部署包我将上传到Github，需要的朋友可以给个Start哟

# 使用注意事项

基于ansible环境，ansible安装略
redis我没有采用免编译各节点需要提前准备gcc-c++环境
elasticsearch各节点需要提前执行 java roles 部署
注意关闭防火墙

# 使用方法

按实际情况更改hosts文件
修改work_yml中对应的nodeipX（集群实际ip）
安装redis集群：ansible-playbook java.yml
安装redis集群：ansible-playbook redis.yml
安装elasticsearchansible-playbook elasticsearch.yml
集群会自动开机启动

# 1.首先验证各个节点能ping通

[root@localhost work_yml]# ansible all -m ping 
192.168.0.177 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.0.179 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
192.168.0.178 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
[root@localhost work_yml]#

# 2.关闭防火墙

[root@localhost work_yml]# ansible all -m service -a 'name=firewalld state=stopped'

# 3.部署java环境

[root@localhost work_yml]# ll
总用量 12
-rw-r--r--. 1 root root 340 1月  26 09:42 elasticsearch.yml
-rw-r--r--. 1 root root 315 1月  26 09:42 java.yml
-rw-r--r--. 1 root root 295 1月  26 09:42 redis.yml
[root@localhost work_yml]# pwd
/etc/ansible/work_yml
[root@localhost work_yml]# ansible-playbook java.yml

验证

[root@localhost work_yml]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
[root@localhost work_yml]#

# 4.部署redis

注意需要提前准备gcc-c++环境

yum install -y gcc-c++

[root@localhost work_yml]# ansible-playbook redis.yml
