ansible-playbook批量部署nginx，nginx
ansible-playbook批量部署nginx，nginx
一．Ansible
ansible是新出现的运维工具是基于Python研发的糅合了众多老牌运维工具的优点实现了批量操作系统配置、批量程序的部署、批量运行命令等功能。
yun install -y ansible二．Playbook编写
首先，ansible主机要和部署的主机要免密钥通讯ssh-keygen
ssh-copyid 192.168.37.26定义主机组
[root@w5 ~]# vim /etc/ansible/hosts
[webserver]
192.168.37.26
创建目录结构
cd /etc/ansible/roles/
mkdir nginx/{files,templates,vars,handlers,meta,default,tasks} -pvfiles/：存储由copy或script等模块调用的文件；
wget http://nginx.org/download/nginx-1.13.6.tar.gztasks/：此目录中至少应该有一个名为main.yml的文件，用于定义各task；其它的文件需要由main.yml进行“包含”调用；
cat main.yml
- name: copy package
copy: src=nginx-1.13.6.tar.gz dest=/usr/local/src/nginx-1.13.6.tar.gz
tags: cppkg
- name: tar nginx
shell: cd /usr/local/src;tar -xf nginx-1.13.6.tar.gz
- name: yum install
yum: name={{ item }} state=latest
with_items:
- openssl-devel
- pcre-devel
- gcc
- name: install nginx
shell: useradd nginx;cd /usr/local/src/nginx-1.13.6;./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre;make && make install
- name: copy conf file
template: src=nginx.conf dest=/usr/local/nginx/conf/nginx.conf
- name: systemctl init
template: src=nginx.service dest=/usr/lib/systemd/system/nginx.service
- name: start nginx service
service: name=nginx state=started enabled=true
handlers/：此目录中至少应该有一个名为main.yml的文件，用于定义各handler；其它的文件需要由main.yml进行“包含”调用；
vars/：此目录中至少应该有一个名为main.yml的文件，用于定义各variable；其它的文件需要由main.yml进行“包含”调用；
vim main.yml
nginxport: "8080"
server_name: "web.wsl.com"
root_dir: "/web"templates/：存储由template模块调用的模板文本；
[root@w5 templates]# cat nginx.conf
user nginx;
worker_processes {{ ansible_processor_vcpus }};
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

location / {

#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#

location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {

# fastcgi_index index.php;

#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {

[root@w5 templates]# cat nginx.service

meta/：此目录中至少应该有一个名为main.yml的文件，定义当前角色的特殊设定及其依赖关系；其它的文件需要由main.yml进行“包含”调用；
default/：此目录中至少应该有一个名为main.yml的文件，用于设定默认变量；
三．定义一个主调用文件
[root@w5 ansible]# pwd
/etc/ansible
[root@w5 ansible]# cat nginx.yaml
- hosts: webserver
remote_user: root
roles:
- nginx
四．检测语法
[root@w5 ansible]# ansible-playbook --syntax-check /etc/ansible/nginx.yaml
playbook: /etc/ansible/nginx.yaml五．测设部署
[root@w5 ansible]# ansible-playbook -C /etc/ansible/nginx.yaml[root@w5 ansible]# ansible-playbook /etc/ansible/nginx.yaml
