1. 配置服务器初始化
1.1) 关闭防火墙和selinux
1 [root@test-1 ~]# /bin/systemctl stop firewalld 2 [root@test-1 ~]# /bin/systemctl disable firewalld 3 [root@test-1 ~]# getenforce #查看selinux是否开启 4 Enforcing #enforcing表示selinux开启的， 5 [root@test-1 ~]# sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/selinux/config #修改配置文件，需要重启才后永久关闭 6 [root@test-1 ~]# setenforce 0 #临时关闭selinx 7 [root@test-1 ~]# getenforce #查看是否关闭 8 Disabled

提示：注意以下的配置的hosts文件的IP要根据自己的环境IP配置
1 [root@test-1 ~]# vim /etc/ansible/hosts 2 [root@test-1 ~]# cat /etc/ansible/hosts 3 # This is the default ansible ‘hosts‘ file. 4 # 5 # It should live in /etc/ansible/hosts 6 # 7 # - Comments begin with the ‘#‘ character 8 # - Blank lines are ignored 9 # - Groups of hosts are delimited by [header] elements 10 # - You can enter hostnames or ip addresses 11 # - A hostname/ip can be a member of multiple groups 12 # 13 # Ex 1: Ungrouped hosts, specify before any group headers. 14 [localhost] 15 192.168.200.131 ansible_host_pass=‘123456‘ 16 [web1] 17 192.168.200.132 ansible_host_pass=‘123456‘ 18 192.168.200.133 ansible_host_pass=‘123456‘ 19 20 [tomcat1] 21 192.168.200.134 ansible_host_pass=‘123456‘ 22 23 24 [mysql] 25 192.168.200.135 ansible_host_pass=‘123456‘ 26 27 [redis] 28 192.168.200.136 ansible_host_pass=‘123456‘ 29 30 # green.example.com 31 # blue.example.com 32 # 192.168.100.1 33 # 192.168.100.10 34 # 35 # Ex 2: A collection of hosts belonging to the ‘webservers‘ group 36 # 37 # [webservers] 38 # alpha.example.org 39 # beta.example.org 40 # 192.168.1.100 41 # 192.168.1.110 42 # 43 # If you have multiple hosts following a pattern you can specify 44 # them like this: 45 # 46 # www[001:006].example.com 47 # 48 # Ex 3: A collection of database servers in the ‘dbservers‘ group
3. 配置服务器免之间密钥通信
3.1) 创建免密钥
1 [root@test-1 ~]# ssh-keygen -t rsa 2 Generating public/private rsa key pair. 3 Enter file in which to save the key (/root/.ssh/id_rsa): 4 Enter passphrase (empty for no passphrase): 5 Enter same passphrase again: 6 Your identification has been saved in /root/.ssh/id_rsa. 7 Your public key has been saved in /root/.ssh/id_rsa.pub. 8 The key fingerprint is: 9 SHA256:lhTKHMoe5UjsWvb3xRHKeQVposFktqZnUONEtq3OEV8 root@test-1 10 The key‘s randomart image is: 11 +---[RSA 2048]----+ 12 | .. o+@ .o | 13 | o.B Xo*. + . | 14 | .= * B+.=Eo | 15 | .+. =.=+.o | 16 | +... S .o . | 17 | . .*.. o | 18 | .o. . | 19 | . | 20 | | 21 +----[SHA256]-----+
提示：
ssh-keygen -t rsa需要在每台的测试服务器上运行
3.2) 拷贝密钥到其他服务器上
1 [root@test-1 ~]# ssh-copy-id 192.168.200.132 2 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" 3 /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed 4 /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys 5 root@192.168.200.132‘s password: 6 Permission denied, please try again. 7 root@192.168.200.132‘s password: 8 9 Number of key(s) added: 1 10 11 Now try logging into the machine, with: "ssh ‘192.168.200.132‘" 12 and check to make sure that only the key(s) you wanted were added. 13 14 [root@test-1 ~]# ssh-copy-id 192.168.200.133 15 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" 16 /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed 17 /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys 18 root@192.168.200.133‘s password: 19 20 Number of key(s) added: 1 21 22 Now try logging into the machine, with: "ssh ‘192.168.200.133‘" 23 and check to make sure that only the key(s) you wanted were added. 24 25 [root@test-1 ~]# ssh-copy-id 192.168.200.134 26 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" 27 The authenticity of host ‘192.168.200.134 (192.168.200.134)‘ can‘t be established. 28 ECDSA key fingerprint is SHA256:tLhcv0ggEH8CXLX8raKfSu4pUHrHVL/3eWjACu9GbWo. 29 ECDSA key fingerprint is MD5:9b:f7:cf:6d:c1:dc:49:fb:fa:5b:6a:43:8d:9a:1b:91. 30 Are you sure you want to continue connecting (yes/no)? yes 31 /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed 32 /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys 33 root@192.168.200.134‘s password: 34 35 Number of key(s) added: 1 36 37 Now try logging into the machine, with: "ssh ‘192.168.200.134‘" 38 and check to make sure that only the key(s) you wanted were added. 39 40 [root@test-1 ~]# ssh-copy-id 192.168.200.135 41 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" 42 The authenticity of host ‘192.168.200.135 (192.168.200.135)‘ can‘t be established. 43 ECDSA key fingerprint is SHA256:tLhcv0ggEH8CXLX8raKfSu4pUHrHVL/3eWjACu9GbWo. 44 ECDSA key fingerprint is MD5:9b:f7:cf:6d:c1:dc:49:fb:fa:5b:6a:43:8d:9a:1b:91. 45 Are you sure you want to continue connecting (yes/no)? yes 46 /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed 47 /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys 48 root@192.168.200.135‘s password: 49 50 Number of key(s) added: 1 51 52 Now try logging into the machine, with: "ssh ‘192.168.200.135‘" 53 and check to make sure that only the key(s) you wanted were added.
3.3) 验证是否可以从ansible主服务器连接到其他管理服务端服务器
1 [root@test-1 ~]# ssh 192.168.200.132 2 Last failed login: Thu Sep 19 12:17:05 EDT 2019 from 192.168.200.131 on ssh:notty 3 There was 1 failed login attempt since the last successful login. 4 Last login: Thu Sep 19 12:14:13 2019 from 192.168.200.1 5 6 [root@test-2 ~]# logout 7 Connection to 192.168.200.132 closed. 8 [root@test-1 ~]# ssh 192.168.200.133 9 Last login: Thu Sep 19 12:14:17 2019 from 192.168.200.1 10 11 [root@test-3 ~]# logout 12 Connection to 192.168.200.133 closed. 13 [root@test-1 ~]# ssh 192.168.200.134 14 Last login: Thu Sep 19 12:14:18 2019 from 192.168.200.1 15 16 [root@test-4 ~]# logout 17 Connection to 192.168.200.134 closed. 18 [root@test-1 ~]# ssh 192.168.200.135 19 Last login: Thu Sep 19 12:14:25 2019 from 192.168.200.1 20 21 [root@test-5 ~]# logout 22 Connection to 192.168.200.135 closed.
提示：
验证没问题，都可以连接
4. ansible连接是否ping是正常的
4.1） ansible使用ping，看主机是否正常
1 [root@test-1 ~]# ansible web1 -m ping 2 192.168.200.133 | SUCCESS => { 3 "ansible_facts": { 4 "discovered_interpreter_python": "/usr/bin/python" 5 }, 6 "changed": false, 7 "ping": "pong" 8 } 9 192.168.200.132 | SUCCESS => { 10 "ansible_facts": { 11 "discovered_interpreter_python": "/usr/bin/python" 12 }, 13 "changed": false, 14 "ping": "pong" 15 } 16 [root@test-1 ~]# ansible mysql -m ping 17 192.168.200.135 | SUCCESS => { 18 "ansible_facts": { 19 "discovered_interpreter_python": "/usr/bin/python" 20 }, 21 "changed": false, 22 "ping": "pong" 23 }
5. ansible-playbook通常github拉取部署
5.1) 创建ansible目录
1 [root@test-1 ~]# mkdir -p /ansible
5.2) 创建github目录拉取代码
1 [root@test-1 ~]# mkdir -p /github 2 [root@test-1 ~]# cd /github/ 3 [root@test-1 github]# ll 4 total 0
5.3) 安装git拉取工具
1 [root@test-1 github]# yum install git -y 2 [root@test-1 github]# git clone https://github.com/tiaotiaodan/ansible.git 3 Cloning into ‘ansible‘... 4 remote: Enumerating objects: 58, done. 5 remote: Counting objects: 100% (58/58), done. 6 remote: Compressing objects: 100% (40/40), done. 7 remote: Total 58 (delta 5), reused 58 (delta 5), pack-reused 0 8 Unpacking objects: 100% (58/58), done. 9 [root@test-1 github]# ll 10 total 0 11 drwxr-xr-x 5 root root 79 Sep 19 13:28 ansible
5.4) 拷贝ansible-playbook配置文件到/ansible下
1 [root@test-1 github]# cd ansible/ 2 [root@test-1 ansible]# ll 3 total 8 4 drwxr-xr-x 2 root root 17 Sep 19 13:28 group_vars 5 -rw-r--r-- 1 root root 326 Sep 19 13:28 hosts 6 drwxr-xr-x 7 root root 68 Sep 19 13:28 roles 7 -rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml 8 [root@test-1 ansible]# cp -a * /ansible/ 9 [root@test-1 ansible]# cd /ansible/ 10 [root@test-1 ansible]# ll 11 total 8 12 drwxr-xr-x 2 root root 17 Sep 19 13:28 group_vars 13 -rw-r--r-- 1 root root 326 Sep 19 13:28 hosts 14 drwxr-xr-x 7 root root 68 Sep 19 13:28 roles 15 -rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml
6. 部署ansible-playbook的lnmp环境
6.1） 进入ansible目录
1 [root@test-1 ansible]# cd /ansible/ 2 [root@test-1 ansible]# ll 3 total 8 4 drwxr-xr-x 2 root root 17 Sep 19 13:28 group_vars 5 -rw-r--r-- 1 root root 326 Sep 19 13:28 hosts 6 drwxr-xr-x 7 root root 68 Sep 19 13:28 roles 7 -rw-r--r-- 1 root root 323 Sep 19 13:28 site.yaml
6.2) 检查配置文件
1 [root@test-1 ansible]# ansible-playbook --syntax-check site.yaml 2 3 playbook: site.yaml
6.3) 执行配置文件
1 [root@test-1 ansible]# ansible-playbook site.yaml 2 3 PLAY [install nginx, php and www]

8. 浏览器验证是否正常
8.1) 浏览器请求
提示：
1、本次用了一台服务器进行验证测试，
2、在生产环境应该是用域名请求，负载均衡到随机每台服务器。
