打开git bash 连接ansible服务器，然后进入deploy用户
#ssh [email protected]
进入python3.6虚拟环境
#su - deploy
#source .py3-a2.5-env/bin/activate
加载ansible 2.5版本
#source .py3-a2.5-env/ansible/hacking/env-setup -q
验证ansible加载效果
#ansible-playbook --version
1、File模块
登录到目标主机进行预配置工作
#ssh [email protected]
创建两个系统用户
# useradd foo
# useradd deploy
登出，回到ansible的主机，进入到test_playbooks目录。编辑主任务文件,添加测试任务。保存退出
# vi roles/testbox/tasks/main.yml
?
- name: create a file # 创建文件file
file: ‘path=/root/foo.txt state=touch mode=0755 owner=foo group=foo‘
#path为文件路径 #state为所用命令 #mode 为文件权限 #owner 为设置的系统用户名称 #group 为宿主执行测试任务
# ansible-playbook -i inventory/testenv ./deploy.yml
?
查看文件是否创建成功
# ssh [email protected] ls -l /root/foo.txt
创建安装nginx需要的文件，复制下面的脚本，进行保存
# vi roles/testbox/files/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true2、Copy模块
先创建一个files目录，在目录下创建一个脚本文件,添加一下内容，保存退出
# mkdir roles/testbox/files
# vi roles/testbox/files/foo.sh
echo "This is a test script"
编辑主任务配置文件，保存退出。
# vi roles/testbox/tasks/main.yml
?
- name: copy a file
copy: ‘remote_src=no src=roles/testbox/files/foo.sh dest=/root/foo.sh mode=0644 force=yes‘
#remote_src 定义当前拷贝任务是将ansible本地server文件传送到目标主机中
#src 本地文件 传送 #dest 目标主机文件
#mode 设置文件权限 #force 定义拷贝任务强制执行编辑好文件之后，执行任务
# ansible-playbook -i inventory/testenv ./deploy.yml
?
3、Stat模块、Debug模块
编辑主任务配置文件，添加以下内容
# vi roles/testbox/tasks/main.yml
# 获取远程foo.sh的文件状态信息
- name: check if foo.sh exists
stat: ‘path=/root/foo.sh‘
register: script_stat
# 将stat文件信息，放到when的判断语句中，如果判断成功，dubug输出foo.sh exists
- debug: msg="foo.sh exists"
when: script_stat.stat.exists
编辑好文件之后，执行任务
# ansible-playbook -i inventory/testenv ./deploy.yml
?
4、Command/Shell模块
编辑主任务配置文件，添加以下内容
# vi roles/testbox/tasks/main.yml
# 远程执行foo.sh脚本
- name: run the script
command: ‘sh /root/foo.sh‘
编辑好文件之后，执行任务
# ansible-playbook -i inventory/testenv ./deploy.yml
?
5、Template模块、Packaging模块、Service模块
添加一些参数到testenv的文件当中，添加如下参数
# vi vi inventory/testenv
?
server_name=test.example.com
port=80
user=deploy
worker_processes=4
max_open_file=65505
root=/www
创建templates目录，然后创建一个nginx.conf.j2的模块文件，添加配置信息
# mkdir roles/testbox/templates
# vi roles/testbox/templates/nginx.conf.j2
# For more information on configuration, see:
user {{ user }}; # user变量
worker_processes {{ worker_processes }}; # 变量
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections {{ max_open_file }}; #变量
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘
‘$status $body_bytes_sent "$http_referer" ‘
‘"$http_user_agent" "$http_x_forwarded_for"‘;
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
# Load config files from the /etc/nginx/conf.d directory
# The default server is in conf.d/default.conf
#include /etc/nginx/conf.d/*.conf;
server {
listen {{ port }} default_server; # 端口变量
server_name {{ server_name }}; #服务器名称变量
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root {{ root }}; # root变量
index index.html index.htm;
}
error_page 404 /404.html;
location = /404.html {
root /usr/share/nginx/html;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
}
编辑主任务配置文件，添加以下下内容
# vi roles/testbox/tasks/main.yml
# 将模板写入目标主机配置文件
- name: write the nginx config file
template: src=roles/testbox/templates/nginx.conf.j2 dest=/etc/nginx/conf.d/default.conf
# yum安装nginx
- name: ensure nginx is at the latest version
yum: pkg=nginx state=latest
# 启动nginx服务
- name: start nginx service
service: name=nginx state=started编辑好文件之后，执行任务
# ansible-playbook -i inventory/testenv ./deploy.yml
?
检查nginx.conf.j2文件的参数变量，是否写入nginx主配置文件
# ssh [email protected] cat /etc/nginx/conf.d/default.conf
?
检查远程主机nginx是否启动
# ssh [email protected] ps -ef | grep nginx
?
