Jenkins + Ansible + Gitlab(二)

Ansible与Chef，Saltstack的不同

Chef
       Ruby语言编写，C/S架构，配置需要Git依赖
       Recipe脚本编写规范，需要编程经验
Saltstack
      Python语言编写，C/S架构，模块化配置管理
      YAML脚本编写规范，适合大规模集群部署
Ansible
      Python语言编写，无Client，模块化配置管理
      Playbook脚本编写规范，易于上手，适合中小规模快速部署

Ansible配合virtualenv安装配置

机器的防火墙和selinux要关闭...

ansible两种安装模式：

• yum -y install ansible(全局模式，不好)
• git clone https://github.com/ansible/ansible.git（推荐）

1.预先安装Python3.6版本

• [root@ansible ~]# wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz
• [root@ansible ~]# tar xf Python-3.7.2.tar.xz 
• [root@ansible Python-3.7.2]# 
  [root@ansible Python-3.7.2]# ./configure  \
  > --prefix=/usr/local \
  > --with-ensurepip=install \
  > --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
• [root@ansible Python-3.7.2]# make && make altinstall

2.安装virtualenv

pip加速：https://blog.csdn.net/qq_33317586/article/details/84205769

• [root@ansible Python-3.7.2]# which pip3.7
  /usr/local/bin/pip3.7
  [root@ansible Python-3.7.2]# ln -s /usr/local/bin/pip3.7 /usr/local/bin/pip
  [root@ansible Python-3.7.2]# pip install virtualenv

3.创建Ansible账户并安装

• [root@ansible Python-3.7.2]# useradd deploy
• [root@ansible Python-3.7.2]# su - deploy
• [deploy@ansible ~]$ virtualenv -p /usr/local/bin/python3.7 .py3-a2.7.8-env （创建python3.7virtualenv实例）

4.git源代码安装ansible2.6

• [deploy@ansible ~]$ cd /home/deploy/.py3-a2.7.8-env/
• [deploy@ansible .py3-a2.7.8-env]$ which git
  /bin/git
• [deploy@ansible ~]$ git clone https://github.com/ansible/ansible.git

5.加载python3.6 virtualenv环境

• [deploy@ansible ~]$ source /home/deploy/.py3-a2.7.8-env/bin/activate
  (.py3-a2.7.8-env) [deploy@ansible ~]$

6.安装ansible依赖包

• (.py3-a2.7.8-env) [deploy@ansible ~]$ pip install paramiko PyYAML jinja2

7.在python3.6环境下加载ansible2.5

参考https://www.cnblogs.com/yongdaimi/p/7600052.html，使用git branch -r查看远程分支，git branch -a查看所有分支

• (.py3-a2.7.8-env) [deploy@ansible ansible]$ git branch -r | grep stable-2.7
    origin/stable-2.7
• (.py3-a2.7.8-env) [deploy@ansible ansible]$ git checkout stable-2.7  （切换ansible安装版本）
  分支 stable-2.7 设置为跟踪来自 origin 的远程分支 stable-2.7。
  切换到一个新分支 'stable-2.7'
• (.py3-a2.7.8-env) [deploy@ansible ansible]$ git branch
    devel
  * stable-2.7
• (.py3-a2.7.8-env) [deploy@ansible ansible]$ source /home/deploy/.py3-a2.7.8-env/ansible/hacking/env-setup -q （在虚拟环境下加载ansible2.7）

8.验证ansible2.5

• (.py3-a2.7.8-env) [deploy@ansible ansible]$ ansible --version
  ansible 2.7.8.post0 (stable-2.7 8fba0ab199) last updated 2019/02/23 19:12:52 (GMT +800)
    config file = None
    configured module search path = ['/home/deploy/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
    ansible python module location = /home/deploy/.py3-a2.7.8-env/ansible/lib/ansible
    executable location = /home/deploy/.py3-a2.7.8-env/ansible/bin/ansible
    python version = 3.7.2 (default, Feb 23 2019, 18:28:07) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
