Teuthology平台部署是怎样的

本篇文章为大家展示了Teuthology平台部署是怎样的，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

Teuthology架构

软件组成

Teuthology 测试框架所使用到的软件组成如下：

• Jenkins 持续集成工具

• teuthology Ceph 测试套件

• shaman 查询提供软件包的 chacra 节点，水平扩展和调度 chacra 节点

• chacra 提供不同架构二进制包或文件的管理 REST API 接口

  Teuthology部署

  部署paddles/pulpito node

  安装依赖

yum install git python-dev python-virtualenv postgresql postgresql-contrib postgresql-server-dev-all supervisor gcc epel-release

配置postgresql数据库

初始化数据库

postgresql-setup initdbsystemctl start postgresql //启动数据库systemctl enable postgresql

postgresql安装并启动后，会自动生成postgres用户

su - postgres //进入该用户-bash-4.2$ psql //进入数据库postgres=# \password postgres //更改用户postgres的密码

//按照输出的提示输入密码即可

创建数据库实例paddles、shaman

postgres=#create database paddles; // 创建名为paddles的数据库postgres=#create database shaman; // 创建名为shaman的数据库postgres=#create database chacra; // 创建名为chacra的数据库

安装配置paddles

创建paddles用户，并克隆paddles项目

useradd -m paddles -g root -G root //新建用户 paddlessu - paddles //切换到paddles用户下git clone https://github.com/ceph/paddles.git //克隆该项目cd paddlesvirtualenv ./virtualenv //创建python的沙盒环境source ./virtualenv/bin/activate //进入沙盒环境

修改配置文件，paddles中有配置文件的例子，只需要复制一份并修改即可。

cp config.py.in config.py

需要修改的内容

job_log_href_templ= 'http://qa-proxy.ceph.com/teuthology/{run_name}/{job_id}/teuthology.log' # 将qa-proxy.ceph.com/teuthology改成自己对应日志服务器的地址...sqlalchemy = {     # You may use SQLite for testing    'url': ' postgresql://postgres:password@localhost/paddles',    # When you set up PostreSQL, it will look more like:    #'url': 'postgresql+psycopg2://USER:PASSWORD@DB_HOST/DB_NAME',    'echo': True,    'echo_pool': True,    'pool_recycle': 3600,    'encoding': 'utf-8'}

修改/var/lib/pgsql/data/pg_hba.conf,解决初始化paddles环境时的报错Ident authentication failed。

# "local" is for Unix domain socket connections onlylocal   all             all                                     trust# IPv4 local connections:host    all             all             127.0.0.1/32            md5# IPv6 local connections:host    all             all             ::1/128                 trust

修改完后，保存并退出。然后安装相关依赖，初始化环境。

$pip install -r requirements.txt //安装相关依赖$python setup.py develop // 初始化环境$pecan populate config.py// 在postgresql创建paddles需要的表

配置数据迁移工具

$ cp alembic.ini.in alembic.ini$ vi alembic.ini    sqlalchemy.url = postgresql://postgres:password@localhost/paddles$alembic stamp head//触发迁移工具生效

通过supervisord部署paddles服务

#cat /etc/supervisord.d/paddles.ini[program:paddles]user=paddlesenvironment=HOME="/home/paddles", USER="paddles"directory=/home/paddles/paddlescommand=/home/paddles/paddles/virtualenv/bin/gunicorn_pecan -c gunicorn_config.py config.pyautostart=trueautorestart=trueredirect_stderr=truestdout_logfile = /home/paddles/paddles.out.logstderr_logfile = /home/paddles/paddles.err.log

安装配置pulpito

创建pulpito用户，切换到pulpito用户进行部署

#useradd -m pulpito -g root -G root#su - pulpito$git clone https://github.com/ceph/pulpito.git$cd pulpito$virtualenv ./virtualenv

修改配置文件，paddles中有配置文件的例子，只需要复制一份并修改即可。

$cp config.py.in prod.py$vi prod.py

主要的修改部分如下：

………paddles_address = 'http://192.168.122.34:8080' #实际的paddles服务地址………'debug': False,

修改完后，保存并退出。然后安装相关依赖。

$source ./virtualenv/bin/activate$pip install -r requirements.txt //安装相关依赖

通过supervisord部署pulpito服务

#cat /etc/supervisord.d/pulpito.ini[program:pulpito] user=pulpito directory=/home/pulpito/pulpito command=/home/pulpito/pulpito/virtualenv/bin/python run.py environment=HOME="/home/pulpito",USER="pulpito" autostart=true autorestart=true redirect_stderr=true stdout_logfile = /home/pulpito/pulpito.out.log stderr_logfile = /home/pulpito/pulpito.err.log启动supervisorsudo supervisord -c /etc/supervisord.confsudo supervisorctl reloadsudo supervisorctl start all//启动sudo supervisorctl status//查看状态，可以看到paddles 和pulpito的进程启动了检测服务

在浏览器或者终端，访问 http://{ip}:8080/和http://{ip}:8081/就可以了，看到如下界面：

部署shaman

shaman的部署方式分为两种一种是手动部署，另一种通过ansible，在此采用的是手动部署。

安装相关依赖

yum install epel-release gcc gcc-c++ glibc-devel make ncurses-devel openssl-devel autoconf java-1.8.0-openjdk-devel git wget wxBase.x86_64 erlang

安装RabbitMQ

wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-3.6.1-1.noarch.rpm rpm --import https://www.rabbitmq.com/rabbitmq-signing-key-public.asc yum install rabbitmq-server-3.6.1-1.noarch.rpmsystemctl start rabbitmq-server #启动rabbitmq-serversystemctl enable rabbitmq-server #设置rabbitmq-server开机自启动

部署shaman

创建shaman用户，并克隆shaman项目，然后创建沙盒环境。

useradd -m shaman -g root -G root //新建用户shamansu - shaman //切换到shaman用户下git clone https://github.com/ceph/shaman.git //克隆该项目cd shamanvirtualenv ./virtualenv //创建python的沙盒环境source ./virtualenv/bin/activate //进入沙盒环境

安装一些在requirements.txt中没有的软件依赖

pip install --upgrade setuptools pip install --upgrade pippip install "cherrypy>=3.8.0,<9.0.0" pip install wsgiserver

修改配置文件config/dev.py。

$vim config/dev.py...    ],     'debug': False,} ... sqlalchemy_w = {     #'url': 'sqlite:///dev.db',     'url': 'postgresql://postgres:password@localhost/shaman',     'echo': True,     'echo_pool': True,     'pool_recycle': 3600,     'encoding': 'utf-8' } sqlalchemy_ro = {     #'url': 'sqlite:///dev.db',     'url': 'postgresql://postgres:password@localhost/shaman',     'echo': True,     'echo_pool': True,     'pool_recycle': 3600,     'encoding': 'utf-8' } ....

修改config/run.py，需要修改的内容为，其中服务IP根据具体改动：

simpleapp_wsgi_app = deploy('config/dev.py')...server = wsgiserver.CherryPyWSGIServer(('0.0.0.0', 8082), application, server_name='simpleapp')

初始化环境

$pip install -r requirements.txt //安装相关依赖$python setup.py develop // 初始化环境$pecan populate config/dev.py// 在postgresql创建shaman需要的表

配置数据迁移工具

$ cp alembic.ini.in alembic.ini$ vi alembic.ini    sqlalchemy.url = postgresql://postgres:password@localhost/shaman$alembic stamp head//触发迁移工具生效

配置supervisord

通过supervisord部署shaman服务

#cat /etc/supervisord.d/shaman.ini[program:shaman] user=shaman directory=/home/shaman/shaman command=/home/shaman/shaman/virtualenv/bin/python config/run.py environment=HOME="/home/shaman",USER="shaman" autostart=true autorestart=true redirect_stderr=true stdout_logfile = /home/shaman/shaman.out.log stderr_logfile = /home/shaman/shaman.err.log

启动shaman服务

sudo supervisorctl reread && sudo supervisorctl update shaman && sudo supervisorctl start shaman

检测服务

在浏览器或者终端，访问 http://{ip}:8082/就可以了，看到如下界面：

部署chacra

chacra的部署较为复杂，采取的是ansible的方式，但是官方提供的部署文件是针对ubuntu系统的，需要进行改动。

修改playbooks相关文件

修改deploy/playbooks/examples/deploy_test.yml中对应参数

development_server: trueapi_user: "admin"api_key: "secret"graphite_api_key: '1234-asdf-1234'callback_url: "http://{ip}:8082/api/repos/" #shaman的地址callback_user: "admin"callback_key: "secret"health_ping_url: "http://{ip}:8082/api/nodes/" #shaman的地址

修改deploy/playbooks/roles/common/tasks/letsencrypt.yml

#删除下面几行- name: install software-properties-common  apt:    name: software-properties-common    state: latest    update_cache: yes  become: true- name: add certbot PPA  apt_repository:    repo: "ppa:certbot/certbot"  become: true

修改deploy/playbooks/roles/common/templates/systemd/chacra-celery.service.j2

# 由于%I在systemd中有特殊的含义，所有在此将%I改为%%IExecStart={{ app_home }}/bin/celery multi start 5 -Q:1,2 poll_repos,celery -Q:3-5 build_repos -A async --logfile=/var/log/celery/%n%%I.logExecReload={{ app_home }}/bin/celery multi restart 5 -Q:1,2 poll_repos,celery -Q:3-5 build_repos -A async --logfile=/var/log/celery/%n%%I.log

部署chacra

使用ansible-playbook部署ansible服务

检查服务

在浏览器或者终端，访问 http://{ip}:8083/就可以了，看到如下界面：

Teuthology Node

Teuthology部署中官方建议为两个角色scheduler和worker。

创建/etc/teuthology.yaml

内容如下：

lab_domain: didichuxing.com #testnode的域名后缀archive_base: /home/teuthworker/archive # 存储日志信息的地方automated_scheduling: Falsereserve_machines: 0queue_host: 127.0.0.1queue_port: 11300lock_server: 'http://{ip}:8080' # paddles的地址results_server: 'http://{ip}:8080' # paddles的地址results_ui_server: 'http://{ip}:8081' # pulpito的地址#results_sending_email: 'teuthology',results_timeout: 43200# Verify the packagee signaturescheck_package_signatures: falseceph_git_base_url: 'git@git.xiaojukeji.com:chishui/' # gitlab地址ceph_git_url: 'git@git.xiaojukeji.com:chishui/deph.git'ceph_qa_suite_git_url: 'git@git.xiaojukeji.com:chishui/deph.git'use_conserver: Falseconserver_master: 'conserver.front.sepia.ceph.com'conserver_port: 3109max_job_time: 259200  # 3 daysbaseurl_template: 'http://{host}/{proj}-{pkg_type}-{dist}-{arch}-{flavor}/{uri}'use_shaman: Trueshaman_host: '{ip}:8082'src_base_path: /home/teuthworker/srcteuthology_path: /home/teuthworker/src/teuthology_mastersuite_verify_ceph_hash: Falsesuite_allow_missing_packages: False

安装依赖

yum -y install git python-devel python-pip python-virtualenv libevent-devel libvirt-python beanstalkd

启动beanstackd队列：

systemctl start beanstalkdsystemctl enable beanstalkd # 配置开机自启动

部署teuthology

创建teuthology与teuthworker两个用户：

useradd -m teuthology -g root -G rootuseradd -m teuthworker -g root -G root

分别给两个账号授予passwordless sudo access权限：

useradd ubuntuvim /etc/sudoers#添加下面两行teuthology   ALL=(ALL)         NOPASSWD: ALLteuthworker  ALL=(ALL)         NOPASSWD: ALL

scheduler

su - teuthologymkdir ~/srcgit clone https://github.com/ceph/teuthology.git src/teuthology_masterpushd src/teuthology_master/./bootstrappopd

worker

su - teuthworkermkdir ~/srcgit clone https://github.com/ceph/teuthology.git src/teuthology_masterpushd src/teuthology_master/./bootstrappopdmkdir ~/binwget -O ~/bin/worker_start https://raw.githubusercontent.com/ceph/teuthology/master/docs/_static/worker_start.shecho 'PATH="$HOME/src/teuthology_master/virtualenv/bin:$PATH"' >> ~/.profilesource ~/.profilemkdir -p ~/archive/worker_logsworker_start magna 1

使用worker_start来启动一个plana的工作进程

worker_start plana 1

配置teuthology和teuthworker用户与test nodes间的免密登录

ssh-copy-id -i ~/.ssh/id_rsa.pub ubuntu@{machine_type}00x.example.com

Test Nodes

添加ubuntu用户

在每个test node上创建ubuntu用户，并为ubuntu用户授予passwordless sudo access权限。

useradd ubuntupasswd ubuntuNew password: <密码>etype new password: <密码>vim /etc/sudoers#添加下面一行ubuntu All=(ALL) NOPASSWD:ALL

配置ssh

#vim /etc/ssh/sshd_config//更改为下面行#HostKey /etc/ssh/ssh_host_key# HostKeys for protocol version 2HostKey /home/ubuntu/.ssh/id_rsa#HostKey /etc/ssh/ssh_host_rsa_key#HostKey /etc/ssh/ssh_host_dsa_key#HostKey /etc/ssh/ssh_host_ecdsa_key#HostKey /etc/ssh/ssh_host_ed25519_key......PermitRootLogin yes......PubkeyAuthentication yes......PasswordAuthentication yes......#systemctl restart sshd

安装依赖

yum install -y redhat-lsb yum-priorities genisoimage wget

submitting nodes

在paddles中注册test nodes

wget https://raw.githubusercontent.com/ceph/teuthology/master/docs/_static/create_nodes.py

修改create_nodes.py

paddles_url = 'http://{ip}:8080/nodes/' # paddles的地址machine_type = 'plana'lab_domain = 'example.com'# Don't change the user. It won't work at this time.user = 'ubuntu'# We are populating 'plana001' -> 'plana003'machine_index_range = range(1, 4) # 创建了'plana001' -> 'plana003' 3台机器......

日志服务器部署
添加nginx服务配置

server {  listen 80;  server_name {ip};  default_type text/plain;  access_log /var/log/nginx/log-access.log;  error_log /var/log/nginx/log-error.log;  location / {    autoindex on;    alias /home/teuthworker/archive/;  }}

重启nginx服务

systemctl restart nginx

修改paddles配置中的job_log_href_templ的值为：

job_log_href_templ= 'http://{ip}/{run_name}/{job_id}/teuthology.log'
