主机的准备：7台虚拟机 1、Ansible主控制端：主机名：ansible 系统：CentOS 8.5 IP: 10.0.0.8 ansible版本：2.9.27 2、Ansible被控制端-webserver组主机1：主机名：web1 系统：CentOS 7.9 IP: 10.0.0.7 主机2：主机名：web2 系统：CentOS 7.9 IP: 10.0.0.17 3、Ansible被控制端-dbserver组主机1：主机名：db1 系统：ubuntu18.04 IP: 10.0.0.100 主机2：主机名：db2 系统：ubuntu18.04 IP: 10.0.0.102 4、Ansible被控制端-webserver组主机1：主机名：app1 系统：CentOS 8.5 IP: 10.0.0.18 主机2：主机名：app2 系统：CentOS 7.9 IP: 10.0.0.27

1.2、Ansible主机的准备 1.2.1、ansible主机环境的准备以及软件包的安装

[root@Centos8 ~]#hostnamectl set-hostname ansible [root@Centos8 ~]#exit [root@ansible ~]#hostname -I 10.0.0.8 #默认ansible的版本 [root@ansible ~]#yum info ansible Last metadata expiration check: 0:28:15 ago on Thu 31 Mar 2022 09:37:42 PM CST.

Ansible works : over SSH and does not require any software or daemons to be installed : on remote nodes. Extension modules can be written in any language and : are transferred to managed machines automatically.#安装ansible软件 [root@ansible ~]#yum -y install ansible #安装完检查安装的版本 [root@ansible ~]#ansible --version ansible 2.9.27 config file = /etc/ansible/ansible.cfg configured module search path = [/root/.ansible/plugins/modules, /usr/share/ansible/plugins/modules] ansible python module location = /usr/lib/python3.6/site-packages/ansible executable location = /usr/bin/ansible python version = 3.6.8 (default, Sep 10 2021, 09:13:53) [GCC 8.5.0 20210514 (Red Hat 8.5.0-3)]

1.2.2、主控端和被控端基于key验证

#修改ssh服务配置文件 [root@ansible ~]#vim /etc/ssh/ssh_config StrictHostKeyChecking no #编写基于key验证的脚本 [root@ansible ~]#vim ssh_key_for_linux.sh #!/bin/bashPASS=wm521314 END=254IP=`ip a s eth0 | awk -F[ /]+ NR==3print $3` NET=$IP%.*.. /etc/os-releaserm -f /root/.ssh/id_rsa [ -e ./SCANIP.log ] & & rm -f SCANIP.logfor((i=3; i< ="$END"; i++)); do ping -c 1 -w 1$NET$i & > /dev/null& & echo "$NET$i" > > SCANIP.log & done waitssh-keygen -P "" -f /root/.ssh/id_rsa if [ $ID = "centos" -o $ID = "rocky" ]; then rpm -q sshpass || yum -y install sshpass else dpkg -i sshpass & > /dev/null || apt -y install sshpass fisshpass -p $PASS ssh-copy-id -o StrictHostKeyChecking=no $IP AliveIP=(`cat SCANIP.log`) for n in $AliveIP[*]; do sshpass -p $PASS scp -o StrictHostKeyChecking=no -r /root/.ssh root@$n: donefor n in $AliveIP[*]; do scp /root/.ssh/known_hosts $n:.ssh/ done #编写完后运行运行脚本，实现key验证 [root@ansible ~]#bash ssh_key_for_linux.sh

1.2.3、主控端ansible配置

#配置ansible中的主机清单 [root@ansible ~]#vim /etc/ansible/hosts [test] 10.0.0.8 ansible_connection=local[webserver] 10.0.0.7 10.0.0.17[dbserver] 10.0.0.100 10.0.0.102[appserver] 10.0.0.18 10.0.0.27 #查看一下ansible中的主机列表 [root@ansible ~]#ansible all --list hosts (7): 10.0.0.8 10.0.0.7 10.0.0.17 10.0.0.100 10.0.0.102 10.0.0.18 10.0.0.27 [root@ansible ~]#ansible dbserver --list hosts (2): 10.0.0.100 10.0.0.102 #检查机器是否都可以通信使用ping模块 [root@ansible ~]#ansible all -m ping 10.0.0.8 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/libexec/platform-python" , "changed": false, "ping": "pong"10.0.0.7 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/bin/python" , "changed": false, "ping": "pong"10.0.0.17 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/bin/python" , "changed": false, "ping": "pong"10.0.0.100 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/bin/python3" , "changed": false, "ping": "pong"10.0.0.102 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/bin/python3" , "changed": false, "ping": "pong"10.0.0.18 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/libexec/platform-python" , "changed": false, "ping": "pong"10.0.0.27 | SUCCESS => "ansible_facts": "discovered_interpreter_python": "/usr/bin/python" , "changed": false, "ping": "pong"

1.3、准备MySQL5.7.37二进制包
