centos 6.3x64 安装ansible_ui

ansible_ui 安装文档
参考资料： https://github.com/alaxli/ansible_ui/issues/15 
注意，以下安装过程最好都用root用户安装


一. 环境准备
1. lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS
Description: CentOS release 6.3 (Final)
Release: 6.3
Codename: Final




2. uname -a
Linux test42 2.6.32-504.30.3.el6.x86_64 #1 SMP Wed Jul 15 10:13:09 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux




3. python -V
Python 2.6.6


4. mkdir -p /data/soft/app/python2.7/ansible_ui


5. 检查是否安装有pip
pip -V
-bash: pip: command not found


6.安装pip,setuptools, 参考 http://pip-cn.readthedocs.io/en/latest/installing.html, 下载地址： https://bootstrap.pypa.io/ 
a. 下载get-pip.py ，上传至/data/soft/app/python2.6
b. cd /data/soft/app/python2.6/
c. python get-pip.py
d. pip -V,显示 pip 8.1.2 from /usr/lib/python2.6/site-packages (python 2.6)， 则安装成功
7. 修改yum源为163yum源，yum安装的时候会快，并且不会再出现无法解析的问题
a. 参考http://mirrors.163.com/.help/centos.html 
b. 备份/etc/yum.repos.d/CentOS-Base.repo, mv /etc/yum.repos.d/CentOS-Base.repo  /etc/yum.repos.d/CentOS-Base.repo.bak
c. cp /data/soft/app/python2.6/CentOS6-Base-163.repo /etc/yum.repos.d/
d. yum clean all
e. yum makecache








8. 安装相关库
yum install -y gcc gcc-c++
注：如遇到错误：Downloading Packages:
http://mirrors.163.com/centos/6/os/x86_64/Packages/cpp-4.4.7-17.el6.x86_64.rpm: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'mirrors.163.com'"
通过如下方式解决：打开文件/etc/resolv.conf在其中添加：
nameserver 8.8.8.8
nameserver 8.8.4.4
search localdomain
yum install -y git
yum install -y openldap-devel
yum install -y python-devel
yum install -y libffi-devel
yum install -y openssl-devel
yum install -y libjpeg-devel
yum install -y zlib-devel
yum install -y python-setuptools
yum install -y mysql-devel
yum install -y  sshpass
9. 配置sshpass, 如使用192.168.0.xx免密登录，按如下步骤执行
a. ssh  -o StrictHostKeyChecking=no  192.168.0.xx
b. ssh-keygen -t rsa
c. ssh-copy-id -i ~/.ssh/id_rsa.pub 192.168.0.xx
d. ssh '192.168.0.xx'
如果这一步能够登录成功，说明配置成功



10. 安装最新版本的python
a. 下载python2.7.11 源码并上传至/data/soft/app/python2.7， 切换当前工作目录为/data/soft/app/python2.7
b. tar -xf Python-2.7.11.tgz
c. cd Python-2.7.11
d. ./configure --prefix=/usr/local
e. make && make install
f. cd /usr/local/bin/
g. ./python -V,  显示 Python 2.7.11






二. 使用virtualenv创建python2.7沙盒环境
1. pip install virtualenv
2. cd /data/soft/app/python2.7/
3. mkdir env
4. virtualenv --python=python2.7 --no-site-packages env/
5. source ./env/bin/activate
6. deactivate


三. 安装ansible_ui 及数据库配置
1. cd /data/soft/app/python2.7/ansible_ui
2. git clone https://github.com/alaxli/ansible_ui.git
3. mkdir -p ansible_ui/playbooks, 此路径为存放playbook的路径
4. /data/soft/app/python2.7/ansible_ui/ansible_ui, 确认此目录下有manage.py， 激活python 虚拟环境， source ./env/bin/activate
5. 开始安装ansible_ui
--使用pip 安装的时候不要使用sudo,否则会切换到python2.6.6的pip安装, 会导致安装过程中出现很多问题
pip install setuptools_scm
pip install -r requirements.txt
pip install Pillow
pip install django-guardian==1.3.0
pip install ansible==1.9.6

6. 配置数据库， cd desktop/core/internal， vim settings_local.py, 修改后如下
# Database settings
DATABASES = {
   'default': {
'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
'NAME': 'ansible',                      # Or path to database file if using sqlite3.
'USER': 'ansibleuser',                      # Not used with sqlite3.
'PASSWORD': 'xxxxxx',                  # Not used with sqlite3.
'HOST': '192.168.0.xx',
'PORT': '3306',                      # Set to empty string for default. Not used with sqlite3.
   },
}


# Mail settings
MAIL_SENDER = "[email protected]"
MAIL_SMTP = "smtp.xx.com"


# Ansible-playbook path
ANSIBLE_PLAYBOOK = '/data/soft/app/python2.7/ansible_ui/playbooks'
7. 在数据库中创建用户并授权
1. 登录192.168.0.xx， mysql -u root -p
2. 在mysql中执行如下
create database ansible CHARACTER SET utf8;
grant all on ansible.* to ansibleuser@'%' identified by 'xxxxxx';
8. 初始化数据库，cd /data/soft/app/python2.7/ansible_ui/ansible_ui, 执行如下命令
***以下命令执行过程中，会要求你设置一个superuser和密码，请记录下此用户名和密码，此用户名和密码就是登录ansible_ui的超级用户
python manage.py schemamigration desktop.apps.account --init
python manage.py schemamigration desktop.apps.ansible --init
python manage.py syncdb
python manage.py migrate ansible
python manage.py migrate account
python manage.py migrate kombu.transport.django
python manage.py migrate djcelery
python manage.py migrate guardian





9. 配置supervisord和ansible
a. cd /data/soft/app/python2.7/ansible_ui/ansible_ui/celery-conf/
b. vim supervisord.conf,查找program:ansible_celeryd，修改command中 virtualenv 和 ansible_ui home, 修改后如下command = /data/soft/app/python2.7/env/bin/python /data/soft/app/python2.7/ansible_ui/ansible_ui/manage.py celeryd -B -l info
c. cd /data/soft/app/python2.7/ansible_ui/ansible_ui
d. cp ansible-conf/ansible.cfg ~/.ansible.cfg


10. 启动
a. supervisord -c celery-conf/supervisord.conf
b. python manage.py runserver 0.0.0.0:8000 




至此，ansible_ui已安装完毕，并且使用的是远程mysql数据库(192.168.0.xx)
