Jenkins+Ansible+Gitlab自动化部署三剑客-Ansible本地搭建

可以通过git bash连接linux

关闭防火墙，禁用防火墙开机启动，并更爱selinux文件，重启

 

 重新登录并检查禁用

getenforce

安装git

yum -y install git nss curl

下载python安装包

wget http://www.python.org/ftp/python/3.6.5/Python-3.6.5.tar.xz

解压 tar xf Python-3.6.5.tar.xz

 cd Python-3.6.5

./configure --prefix=/usr/local --with-ensurepip=install --enable-shared LDFLAGS="-wl, -rpath /usr/local/lib"

make && make altinstall

查看pip3.6

which pip3.6

给pip3.6做软连接

ln -s /usr/local/bin/pip3.6 /usr/local/bin/pip

安装virtualenv工具

pip install virtualenv

 在新用户下创建virtualenv

useradd deploy

su - deploy

virtualenv -p /usr/local/bin/python3.6 .py3-a2.5-env

cd /home/deploy/.py3-a2.5-env

which git

没有安装

切换到root安装git

su - root

安装git

yum -y install git nss curl

切换回用户deploy

su - deploy

git克隆ansible

git clone https://github.com/ansible/ansible.git

加载virtualenv环境

source /home/deploy/.py3-a2.5-env/bin/activate

安装ansible依赖包

pip install parammiko PyYAML jinja2

把ansible源代码移动到python3.6的virtualenv环境下

mv ansible .py3-a2.5-env/

cd .py3-a2.5-env/ansible/

切换到ansible到2.5版本

git checkout stable-2.5

加载

source /home/deploy/.py3-a2.5-env/ansible/hacking/envsetup -q

看是否安装成功

ansible --version

加载python 环境和ansible环境

su -deploy

source .py3-a2.5-env/bin/activate

source .py3-a2.5-env/ansible/hancking/env-setup -q

 

验证是否开启ansible服务

ansible-playbook --version

创建若干文件

mkdir test_playbooks

cd test_playbooks/

mkdir inventory

mkdir roles

cd inventory/

 vi testenv

[testservers]

test.example.com

[testservers:vars]

server_name=test.example.com

user=root

output=/root/test.txt

 cd ..

ls

cd  roles/

mkdir testbox

cd testbox

mkdir tasks

cd tasks/

 

vim main.yml

- name: Print server name and user to remote testbox

  shell: "echo 'Currently {{ user }} is logining {{ server_name}}' > {{ output}}" 

 输入一条数据到目标主机

回到test_playbooks

 pwd

cd ../../..

pwd

vim deploy.yml (入口文件)

- host: "testservers"

  gather_facts: true

  remote_user: root

  roles:

    - testbox

 

tree .

 

创建密钥

 

实际操作

连接ansible服务器

su -deploy

启动py3

source .py3-a2.5-env/bin/activate

启动ansible

source .py3-a2.5-env/ansible/hacking/env-setup -q

查看ansible是否启动

ansible-playbook --version

为了推到目标服务器的任务顺利执行

ssh root@test.example.com

useradd foo

useradd deploy

mkdir /etc/nginx

给目标服务器安装nginx环境

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.e17.ngx.noarch.rpm

 

退出回到ansible

pwd

ls

cd test_playbooks/

ls

vi roles/testbox/tasks/main.yml

- name: create a file

  file: 'path=/root/foo.txt state=touch mode=0775 owner=foo group=foo'

 

测试脚本是否可用

ansible-playbook -i inventory/testenv ./deploy.yml

另外的检查方式

ssh root@test.example.com ls -l /root/foo.txt

创建另一个模块

mkdir /root/testbox/files

vi roles/testbox/files/foo.sh

 echo "This is a test script"

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'

 

然后执行，看是否执行成功

ansible-playbook -i inventory/testenv ./deploy.yml

vi roles/testbox/tasks/main.yml

获取文件状态信息

- name: check if foo.sh exists

  stat: 'path=/root/foo.sh'

register: script_stat

状态判断

- debug: msg="foo.sh exists"

  when: script_stat.stat.exists

执行并查看状态

ansible-playbook -i inventory/testenv ./deploy.yml

vi roles/testbox/tasks/main.yml

执行远程脚本

- name: run the script

  command: 'sh /root/foo.sh'

 

ansible-playbook -i inventory/testenv ./deploy.yml

vim inventory/testenv

server_name=test.example.com

port=80

user=deploy

worker_processes=4

max_open_file=65505

root=/www

 mkdir roles/testbox/templates

vim roles/testbox/templates/nginx.conf.j2

 

 vi roles/testbox/tasks/main.yml

 

查看执行状态

ansible-playbook -i inventory/testenv ./deploy.yml

另一种查看，然后有配置，并且替换了参数，说明成功

ssh root@test.example.com cat /etc/nginx/nginx.conf

查看nginx是否启动成功
