一、网站拓扑

　　ansible主机inventory的情况：
　　# cat ansible_inventory.txt
　　[front]
　　10.11.7.224 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=xuAK
　　10.11.5.209 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=pwByh
　　[redmon]
　　10.11.7.205 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WlkW
　　10.11.7.202 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=iJMfZ
　　10.11.7.201 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WxB6
　　[web]
　　10.11.7.207 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=VtxR3
　　10.11.7.206 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=adR5I
　　10.11.7.192 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=W5f4
　　[db]
　　10.11.7.200 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=vLmb
　　10.11.7.195 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=WOg
　　10.11.7.193 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_pass=fZrLv
　　二、安装部分
　　1、准备所需的源
　　下面是nginx源为例，具体参考博客centos7配置更新源、epel源
　　# cat /etc/yum.repos.d/ngx.repo
　　# filename: nginx.repo
　　[nginx]
　　name=centos7 nginx repo
　　baseurl=http://nginx.org/packages/centos/7/$basearch/
　　enabled=1
　　gpgcheck=0
　　#rpm -ivhhttps://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
　　2、准备好所需的安装包（建议下载后，通过拷贝等方式进行安装，有部分关联包，根据安装过程中，出现的提示安装即可）
　　下载包：（nginx为例，部分使用系统默认自带的安装包）
　　# yum install --downloadonly --downloaddir=/root/ans/ningx/ nginx
　　keepalived包使用默认
　　或者使用yumdownloader下载：
　　# yumdownloader --resolve --destdir=/root/ans/ openssl-devel
　　# ls     #安装包
　　ansible_inventory.txt   mongodb  mysql  nginx  redis  resin
　　3、ansible安装各个功能应用程序
　　通过ansible对不同功能的服务器进行安装，具体如下（ntp时间同步可以略过）
　　3.1、安装开发工具：
　　# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "yum groupinstall 'Development Tools' -y"
　　3.2、ntp时间同步
　　# ansible all -i /root/ans/ansible_inventory.txt -m yum -a "name=ntp state=present"
　　# ansible all -i /root/ans/ansible_inventory.txt -m service -a "name=ntpd state=started enabled=yes"
　　# ansible all -i ansible_inventory.txt -m systemd -a "name=ntpd state=restarted enabled=yes"
　　# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "date"
　　#ansible all -i /root/ans/ansible_inventory.txt -m cron -a "name='sync cron' hour=4 user=root job='ntp.sjtu.edu.cn'"
　　定时的结果：
　　# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "crontab -l"
　　# crontab -l
　　#Ansible: sync cron
　　0 4 * * * ntp.sjtu.edu.cn
　　定时取消：
　　# ansible all -i /root/ans/ansible_inventory.txt -m cron -a "name='sync cron' minute=10 hour=4 user=root job='ntp.sjtu.edu.cn' state=absent"
　　新建文件夹，指定存放路径
　　http://www.iyunv.com/thread-211953-1-1.html
　　# ansible all -i /root/ans/ansible_inventory.txt -m shell -a "mkdir /root/ans"
　　或
　　# ansible all -i /root/ans/ansible_inventory.txt -m file -a "path=/root/ans state=directory"
　　查看
　　# ansible all -i /root/ans/ansible_inventory.txt -a "ls -l /root"
　　3.3、安装nginx
　　[front][web]
　　# ansible front,web -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/nginx dest=/root/ans/"
　　# ansible front,web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ivh /root/ans/nginx/*"
　　# ansible front,web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ql nginx"
　　启动与停止
　　# ansible front,web -i /root/ans/ansible_inventory.txt -m systemd -a "name=nginx state=started enabled=yes"
　　# ansible front,web -i /root/ans/ansible_inventory.txt -m systemd -a "name=nginx state=stopped"
　　3.4、keepalived安装
　　[front]
　　# ansible front -i /root/ans/ansible_inventory.txt -m yum -a "name=keepalived state=latest"
　　# ansible front -i /root/ans/ansible_inventory.txt -m service -a "name=keepalived state=start enabled=yes“
　　# ansible front -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ql keepalived"
　　# ansible front -i /root/ans/ansible_inventory.txt -m systemd -a "name=keepalived state=started enabled=yes"
　　# ansible front -i /root/ans/ansible_inventory.txt -m shell -a "ps -ef | grep keepalived" --limit=10.11.7.224
　　3.5、安装resin：（需要安装关联包jdk、openssl-devel）
　　[web]
　　# ls resin/
　　jdk-8u121-linux-x64.rpm  resin-4.0.49-1.x86_64.rpm  RPM-GPG-KEY-caucho
　　# ansible web -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/resin dest=/root/ans/"
　　# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/resin/jdk-8u121-linux-x64.rpm -y”
　　# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "rpm --import /root/ans/resin/RPM-GPG-KEY-caucho"
　　# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "yum install openssl-devel -y"
　　# ansible web -i /root/ans/ansible_inventory.txt -m shell -a "rpm -ivh /root/ans/resin/resin-4.0.49-1.x86_64.rpm"      #也可用使用yum来安装
　　3.6、安装mongodb和Redis：
　　[redmon]
　　# ansible redmon -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/mongodb dest=/root/ans/"
　　# ansible redmon -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/redis dest=/root/ans/"
　　# ansible redmon -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/redis/*.rpm -y"
　　# ansible redmon -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/mongodb/*.rpm -y"
　　3.7、安装mysql（mysql-community-server）：
　　# ansible db -i /root/ans/ansible_inventory.txt -m copy -a "src=/root/ans/mysql dest=/root/ans/"
　　# ansible db -i /root/ans/ansible_inventory.txt -m shell -a "yum install /root/ans/mysql/*.rpm -y"
