Ansible-playbook-roles安装lnmp_安装lnmp环境的playbook

使用roles安装lnmp

nginx

1、准备四台主机
192.168.142.10
192.168.142.20
192.168.142.30
192.168.142.40
2、10作为ansible管理端
首先ssh连接剩下三台主机
3、vim/etc/ansible/hosts
添加[nginxservers]配置nginx ip,[phpservers]php ip,[mysqlservers]mysql ip
4、cd /etc/ansible 
mkdir roles/{nginx,php,mysql}
mkdir -p roles/nginx/{tasks,vars,files,templates,handlers,defaults,meta}
mkdir -p roles/php/{tasks,vars,files,templates,handlers,defaults,meta}
mkdir -p roles/mysql/{tasks,vars,files,templates,handlers,defaults,meta}
touch roles/nginx/{tasks,vars,handlers,defaults,meta}/main.yml
touch roles/php/{tasks,vars,handlers,defaults,meta}/main.yml
touch roles/mysql/{tasks,vars,handlers,defaults,meta}/main.yml
5、准备nginx配置模板文件，需要在管理端下载nginx、php、mysql。
cp /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.j2
mv default.conf.j2 /etc/ansible/roles/nginx/templates/
6、在模板文件中修改j2模板文件
listen       {{http_port}};
server_name  {{host_name}};
root   {{root_dir}};
location ~ \.php$ {
        root           {{root_dir}};
        fastcgi_pass   {{remote_addr}}:{{remote_port}};
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  {{root_dir}}$fastcgi_script_name;
        include        fastcgi_params;
    }
7、在vars文件中准备变量
vim main.yml
http_port: 192.168.142.20:80
host_name: www.kgc.com
root_dir: /usr/share/nginx/html
remote_addr: 192.168.142.30
remote_port: 9000
pkg: nginx
service: nginx
8、tasks
cd tasks
vim init.yml（设置关闭防火墙、selinux）
- name: disable selinux
  command: '/usr/sbin/setenforce 0'
  ignore_errors: true

- name: disable firewalld
  systemd: name=firewalld state=stopped enabled=no
  ignore_errors: true
这个文件可以复用！！
9、编写main.yml
首先可以进入/etc/ansible/roles/nginx/files
vim index.php
<?php
phpinfo();
?>
再将nginx.repo 复制道files中 cp /etc/yum.repos.d/nginx.repo ./

vim /tasks/main.yml

- include: "init.yml"

- name: copy local yum repo file
  copy: src=nginx.repo dest=/etc/yum.repos.d/

- name: install nginx
  yum: name=nginx state=latest

- name: copy index.php
  copy: src=index.php dest={{root_dir}}

- name: copy template configure file
  template: src=default.conf.j2 dest=/etc/nginx/conf.d/default.conf
  notify: restart service

- name: start nginx
  systemd: name=nginx state=started enabled=yes

vim /handlers/main.yml
- name: restart service
  systemd: name=nginx state=restarted

10、创建playbook yml文件
cd /etc/ansible
mkdir playbook

vim lnmproles.yaml

- name: nginx play
  hosts: nginxservers
  remote_user: root
  roles:
  - nginx

ansible-playbook lnmproles.yaml
启动剧本

准备mysql

先在本地安装mysql
yum remove mariadb* -y
cd /etc/yum.repos.d

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
sed -i 's/gpgcheck=1/gpgcheck=0/' mysql-community.repo
yum -y install mysql-community-server
或
wget https://repo.mysql.com/mysql57-community-release-el7-11.noarch.rpm
rpm -ivh mysql57-community-release-el7-11.noarch.rpm
sed -i 's/gpgcheck=1/gpgcheck=0/' mysql-community.repo
yum -y install mysql-server

systemctl start mysqld.service
systemctl enable mysqld.service

grep "password" /var/log/mysqld.log            #在日志文件中找出root用户的初始密码
2021-07-31T07:55:00.366359Z 1 [Note] A temporary password is generated for root@localhost: ga7%<d<0*jD&

grep "password" /var/log/mysqld.log | awk '{print $NF}'

##登录 mysql
mysql -uroot -p
Enter password:         #输入初始密码 ga7%<d<0*jD&

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Admin@123';     #密码设置要求有 大小写字母、数字和符号 组合

grant all privileges on *.* to root@"%" identified by "Admin@123" with grant option;
flush privileges;

yum -y remove mysql57-community-release-el7-10.noarch     #为了防止每次yum操作都会自动更新，卸载这个软件

首先cp /etc/ansible/roles/nginx/tasks/init.yml /etc/ansible/roles/mysql/tasks/

vim /etc/ansible/roles/mysql/tasks/main.yml

- include: init.yml

- name: remove mariadb
  command: 'yum remove mariadb* -y && cd /etc/yum.repo.d'

- name: yum install mysql
  shell: 'wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm && yum -y install mysql57-community-release-el7-10.noarch.rpm'
  ignore_errors: true

- name: replace file
  replace: "path=/etc/yum.repos.d/mysql-community.repo regexp='gpgcheck=1' replace='gpgcheck=0'"

- name: yum install mysql1
  yum: name=mysql-community-server

- name: system mysql
  service: enabled=true name={{svc}} state=started

vim /etc/ansible/roles/mysql/vars/main.yml

svc: mysqld

cd /etc/ansible/playbook
vim /etc/ansible/playbook/lnmproles.yaml
- name: nginx play
  hosts: nginxservers
  remote_user: root
  roles:
  - nginx
 
- name: mysql play
  hosts: mysqlservers
  remote_user: root
  roles:
  - mysql
