1.Ansible-playbook中部署Nginx角色

创建nginx角色所需要的工作目录；

mkdir -p /etc/ansible/playbook/roles/nginxmkdir -p /etc/ansible/playbook/roles/nginx/defaultsmkdir -p /etc/ansible/playbook/roles/nginx/filesmkdir -p /etc/ansible/playbook/roles/nginx/handlersmkdir -p /etc/ansible/playbook/roles/nginx/metamkdir -p /etc/ansible/playbook/roles/nginx/tasksmkdir -p /etc/ansible/playbook/roles/nginx/templatesmkdir -p /etc/ansible/playbook/roles/nginx/vars

制作/etc/ansible/playbook/roles/nginx/files/index.php网页目录；

vim /etc/ansible/playbook/roles/nginx/files/index.php<" />();?>

vim /etc/ansible/playbook/roles/nginx/files/nginx.repo# nginx.repo[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/$releasever/$basearch/gpgcheck=1enabled=1gpgkey=https://nginx.org/keys/nginx_signing.keymodule_hotfixes=true

制作/etc/ansible/playbook/roles/nginx/handlers/main.yml文件，加载nginx的配置模板文件；

vim /etc/ansible/playbook/roles/nginx/handlers/main.yml- name: reload nginxservice: name={{service}}state=reloaded

制作/etc/ansible/playbook/roles/nginx/tasks/init.yml文件；

vim /etc/ansible/playbook/roles/nginx/tasks/init.yml- name: disable firewalldservice: name=firewalldstate=stoppedenabled=noignore_errors: True- name: disable selinuxshell: "/usr/sbin/setenforce 0"ignore_errors: true

制作/etc/ansible/playbook/roles/nginx/tasks/main.yml文件；

2.Ansible-playbook中部署PHP角色

创建php角色所需要的工作目录；

mkdir -p /etc/ansible/playbook/roles/phpmkdir -p /etc/ansible/playbook/roles/php/defaultsmkdir -p /etc/ansible/playbook/roles/php/filesmkdir -p /etc/ansible/playbook/roles/php/handlersmkdir -p /etc/ansible/playbook/roles/php/metamkdir -p /etc/ansible/playbook/roles/php/tasksmkdir -p /etc/ansible/playbook/roles/php/templatesmkdir -p /etc/ansible/playbook/roles/php/vars

制作/etc/ansible/playbook/roles/php/files/index.php的网页文件；

vim /etc/ansible/playbook/roles/php/files/index.php <" />();?>

制作/etc/ansible/playbook/roles/php/handlers/main.yml文件；

vim /etc/ansible/playbook/roles/php/handlers/main.yml - name: reload phpservice: name={{service}} state=reloaded

制作/etc/ansible/playbook/roles/php/tasks/main.yml文件；

/etc/ansible/playbook/roles/php/tasks]# vim main.yml - name: install yum reposhell: "rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm && rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm"ignore_errors: True- name: install phpwith_items:- php72w- php72w-cli- php72w-common- php72w-devel- php72w-embedded- php72w-gd- php72w-mbstring- php72w-pdo- php72w-xml- php72w-fpm- php72w-mysqlnd- php72w-opcacheyum: name={{item}}- name: create php useruser: name={{user_name}}- name: crate web root dirfile: name={{root_dir}} state=directory- name: copy index.phpcopy: src=index.php dest={{root_dir}}- name: modify php configuration filereplace: path=/etc/php.iniregexp=";date.timezone ="replace="date.timezone = Asia/Shanghai"notify: reload php- name: modify username and groupname in www.confreplace: path=/etc/php-fpm.d/www.confregexp="apache"replace="{{user_name}}"notify: reload php- name: modify listen addr in www.confreplace: path=/etc/php-fpm.d/www.confregexp="127.0.0.1:9000"replace="{{http_port}}"notify: reload php- name: modify allowed client in www.confreplace: path=/etc/php-fpm.d/www.confregexp="127.0.0.1"replace="{{remote_addr}}"notify: reload php- name: start phpservice: name={{service}} state=started enabled=yes
