小岛动漫帝 731

前言:

此时大家对“vissim installing plugins”大致比较珍视,兄弟们都需要学习一些“vissim installing plugins”的相关文章。那么小编在网络上汇集了一些有关“vissim installing plugins””的相关文章,希望各位老铁们能喜欢,咱们一起来了解一下吧!

1、运维自动化发展历程及技术应用  本地部署:On-Premises  基础设施即服务:IaaS(Infrastructure as a Service)  平台即服务:PaaS(Platform as a Service)  软件即服务:SaaS(Software as a Service)

2、自动化运维应用场景  

1>文件传输  

2>命令执行    

应用部署    配置管理    任务流编排  

3>程序发布    

预发布:新版本的代码先发布到服务器(跟线上环境完全相同,只是未接入调度器)    

程序发布:不能导致系统故障或造成系统完全不可用;不能影响用户体验    

灰度发布:先发布1/10的服务器,面向少量精准用户,在逐渐增多    

发布路径:      

/nginx1.1      nginx(软链接)      /nginx1.2      在调度机上将一台 real-server 置为 down,停止旧版本的服务,删除旧的软链接,启动新的服务,创建新的软链接,在调度器启用这一批服务器    

自动化灰度发布:脚本、发布平台

3、ansible特性  

1>模块化,有Paramiko,PyYAML,jinja2(模块语言)三个关键模块,支持自定义模块  

2>基于Python语言实现,部署简单,基于python和ssh(默认安装),安全、agentless(无代理,不需要配置代理,主控端直接控制被控端)  

3>支持playbook编排任务  

4>幂等性:一个任务执行1遍和执行n遍效果一样,不因重复执行带来意外情况  

5>无需代理不依赖PKI(无需ssl)  

6>可使用任何编程语言写模块  

7>YAML格式,编排任务,支持丰富的数据结构  

8>较强大的多层解决方案(角色)

4、ansible架构及工作原理

5、ansible主要组成部分  

ansible playbook:任务剧本(任务集),编排定义Ansible任务集的配置文件,由Ansible顺序依次执行,通常是JSON格式的YML文件  

inventory:Ansible管理主机的清单/etc/anaible/hosts  

modules:Ansible执行命令的功能模块,多数为内置核心模块,也可自定义  

plugins:模块功能的补充,如连接类型插件、循环插件、变量插件、过滤插件等,该功能不常用  

API:供第三方程序调用的应用程序编程接口  

ANSIBLE:组合INVENTORY、API、 MODULES、PLUGINS的绿框,可以理解为是ansible命令工具,其为核心执行工具

6、Ansible命令执行来源:  

USER,普通用户,即SYSTEM ADMINISTRATOR  

CMDB (配置管理数据库) API 调用  

PUBLIC/PRIVATE CLOUD API调用  

USER → Ansible Playbook → Ansibile

7、利用ansible实现管理的方式:  

Ad-Hoc即ansible命令,主要用于临时命令使用场景  

Ansible-playbook主要用于长期规划好的,大型项目的场景,需要有前提的规划  

Ansible-playbook (剧本) 执行过程:    

将已有编排好的任务集写入Ansible-Playbook    通过ansible-playbook命令分拆任务集至逐条ansible命令,按预定规则逐条执行  

Ansible主要操作对象:    

HOSTS主机    NETWORKING网络设备  

注意事项:  

➢执行ansible的主机一般称为主控端,中控,master或堡垒机  

➢主控端Python版本需要2.6或以上  

➢被控端Python版本小于2.4需要安装python-simplejson  

➢被控端如开启SELinux需要安装libselinux-python  

➢windows不能做为主控端

8、安装(本机采用rpm安装,实验)  

1>rpm包安装:EPEL源

yum install ansible -y

  2>编译安装:

yum -y install python-jinja2 PyYAML python-paramiko python-babel python-cryptotar xf ansible-1.5.4.tar.gzcd ansible-1.5.4python setup.py buildpython setup.py installmkdir /etc/ansiblecp -r examples/* /etc/ansible

  3>Git方式:

git clone git://github.com/ansible/ansible.git --recursivecd ./ansiblesource ./hacking/env-setup

  4>pip安装:pip是安装Python包的管理器,类似yum

yum install python-pip python-develyum install gcc glibc-devel zibl-devel rpm-bulid openssl-develpip install --upgrade pippip install ansible --upgrade

  5>确认安装: ansible --version

9、相关文件  

1>配置文件    

/etc/ansible/ansible.cfg 主配置文件,配置ansible工作特性    /etc/ansible/hosts 主机清单    /etc/ansible/roles/ 存放角色的目录  

2>程序    

/usr/bin/ansible 主程序,临时命令执行工具    /usr/bin/ansible-doc 查看配置文档,模块功能查看工具    /usr/bin/ansible-galaxy 下载/上传优秀代码或Roles模块的官网平台    /usr/bin/ansible-playbook 定制自动化任务,编排剧本工具/usr/bin/ansible-pull远程执行命令的工具    /usr/bin/ansible-vault 文件加密工具    /usr/bin/ansible-console 基于Console界面与用户交互的执行工具  

3>主机清单inventory    

Inventory主机清单    ansible的主要功用在于批量主机操作,为了便捷地使用其中的部分主机,可以在inventory file中将其分组命名    默认的inventory file为/etc/ansible/hosts    inventory file可以有多个,且也可以通过Dynamic Inventory来动态生成  

4>/etc/ansible/hosts文件格式  

inventory文件遵循INI文件风格,中括号中的字符为组名。可以将同一个主机同时归并到多个不同的组中;此外,当如若目标主机使用了非默认的SSH端口,还可以在主机名称之后使用冒号加端口号来标明

[root@ansible ~]#vim /etc/ansible/hosts

也可以配置域名解析,使用域名代替ip,如果ssh默认端口号有改动不是22端口,则 ip/域名:端口

Ansible配置文件  Ansible配置文件/etc/ansible/ansible.cfg (一般保持默认)

[defaults]#inventory = /etc/ansible/hosts     #主机列表配置文件#library = /usr/share/my_modules/   #库文件存放目录#remote_tmp = $HOME/.ansible/tmp    #临时py命令文件存放在远程主机目录#local_tmp = $HOME/.ansible/tmp     #本机的临时命令执行目录#forks = 5                          #默认并发数#sudo_user = root                   #默认sudo用户#ask_sudo_pass = True               #每次执行ansible命令是否询问ssh密码#ask_pass = True#remote_port = 22#host_key_checking = False          #检查对应服务器的host_key,建议取消注释,要不然得先建立连接(/root/.ssh/known_hosts)Ansible才能连接成功#log_path=/var/log/ansible.log      #日志文件

Ansible配置文件保持默认,建议开启:host_key_checking = False,log_path=/var/log/ansible.log

10、Ansible系列命令

ansible ansible-doc ansible-playbook ansible-vault ansible-console ansible-galaxy ansible-pull

ansible-doc 显示模块帮助

ansible-doc [options] [module...]-a 显示所有模块的文档-l,--list 列出可用模块-s,--snippet显示指定模块的playbook片段

示例:

ansible-doc -l      列出所有模块ansible-doc ping    查看指定模块帮助用法ansible-doc -s ping 查看指定模块帮助用法(短帮助)

ansible通过ssh实现配置管理、应用部署、任务执行等功能,建议配置ansible端能基于密钥认证的方式联系各被管理节点

  ansible <host-pattern> [-m module_name] [-a args]

    --version显示版本

    -m module指定模块,默认为command

    -v详细过程-vv -vvv更详细

    --list-hosts显示主机列表,可简写-list

    -k, --ask-pass提示输入ssh连接密码,默认Key验证

    -K, --ask-become-pass提示输入sudo时的口令

    -C, --check检查,并不执行

    -T, --timeout=TIMEOUT执行命令的超时时间,默认10s

    -u, --user=REMOTE_USER执行远程执行的用户

    -b, --become代替旧版的sudo切换

[root@ansible ~]#ansible all --list  hosts (2):    192.168.100.10    192.168.100.20

  *:通配符

  ansible "*" -m ping

  ansible 192.168.100.* -m ping

  ansible "*server" -m ping

[root@ansible ~]#ansible *server -m ping192.168.100.20 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.100.10 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}

  或关系

  ansible "webserver:dbserver" -m ping

  ansible "192.168.100.10:192.168.100.20" -m ping

[root@ansible ~]#ansible "webserver:dbserver" -m ping192.168.100.20 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}192.168.100.10 | SUCCESS => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": false,     "ping": "pong"}

  逻辑与

  ansible "webserver:&dbserver" -m ping

  在webserver组并且在dbserver组中的主机

  逻辑非

  ansible 'webserver:!dbserver' -m ping

  在webserver组,但不在dbserver组中的主机

  注意:此处为单引号

  综合逻辑

  ansible 'webserver:dbserver:&appserver:!ftpserver' -m ping

  正则表达式

  ansible "webserver:&dbserver" -m ping

  ansible“ ~(web|db).*\.yang\.com”-m ping

11、Ansible命令执行过程

  

1.加载自己的配置文件默认/etc/ansible/ansible.cfg

  2.加载自己对应的模块文件,如command

  3.通过ansible将模块或命令生成对应的临时py文件,并将该文件传输至远程服务器的对应执行用户$HOME/.ansible/tmp/ansible-tmp-数字/XXX.PY文件

  4.给文件+x执行

  5.执行并返回结果

  6.删除临时py文件,sleep 0退出

  执行状态:

    绿色:执行成功并且不需要做改变的操作

    黄色:执行成功并且对目标主机做变更

    红色:执行失败

12、Ansible常见模块

  各种模块的使用,可以ansible-doc -s service先查看帮助,再进行使用  1>command模块:在远程主机执行命令,默认模块,可忽略-m选项

[root@ansible ~]#ansible all -m command -a 'hostname'192.168.100.20 | CHANGED | rc=0 >>node-2192.168.100.10 | CHANGED | rc=0 >>node-1[root@ansible ~]#ansible all -m command -a 'echo yang | passwd --stdin yang'192.168.100.20 | CHANGED | rc=0 >>yang | passwd --stdin yang    #没有成功,当字符串打印出来了192.168.100.10 | CHANGED | rc=0 >>yang | passwd --stdin yang    #没有成功,当字符串打印出来了

此命令不支持$VARNAME < > | ; & 等,需要使用shelI模块实现

2>shell模块:和command相似,用shell执行命令

[root@ansible ~]#ansible all -m shell -a 'echo yang | passwd --stdin yang'192.168.100.20 | CHANGED | rc=0 >>更改用户 yang 的密码 。passwd:所有的身份验证令牌已经成功更新。192.168.100.10 | CHANGED | rc=0 >>更改用户 yang 的密码 。passwd:所有的身份验证令牌已经成功更新。

调用bash执行命令类似cat /tmp/stanley.md | awk -F'|' '{print $1,$2}' &>/tmp/example.txt 这些复杂命令,即使使用shell也可能会失败,解决办法:写到脚本,copy到远程,执行,再把需要的结果拉回执行命令的机器

3>script模块:运行脚本  -a "/PATH/TO/SCRIPT_FILE"

[root@ansible ~]#./hello.sh     #当前Ansible机器上的脚本:实现打印hello,输出主机名hellomy hostname is ansible.localdomain[root@ansible ~]#ansible all -m script -a '/root/hello.sh'192.168.100.20 | CHANGED => {    "changed": true,     "rc": 0,     "stderr": "Shared connection to 192.168.100.20 closed.\r\n",     "stderr_lines": [        "Shared connection to 192.168.100.20 closed."    ],     "stdout": "hello\r\nmy hostname is node2.localdomain\r\n",     "stdout_lines": [        "hello",         "my hostname is node2.localdomain"    ]}192.168.100.10 | CHANGED => {    "changed": true,     "rc": 0,     "stderr": "Shared connection to 192.168.100.10 closed.\r\n",     "stderr_lines": [        "Shared connection to 192.168.100.10 closed."    ],     "stdout": "hello\r\nmy hostname is node1.localdomain\r\n",     "stdout_lines": [        "hello",         "my hostname is node1.localdomain"    ]}

4>copy模块:从服务器复制文件到客户端

[root@ansible ~]#ansible all -m copy -a 'src=/root/hello.sh dest=/root/'    #src:指定源文件  dest:指定目标文件存放目录192.168.100.20 | CHANGED => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": true,     "checksum": "63ff849c6cde8cd1eef04e0472e832d8407eca00",     "dest": "/root/hello.sh",     "gid": 0,     "group": "root",     "md5sum": "c426adca4193658a2183f59d726cc2dc",     "mode": "0644",     "owner": "root",     "size": 58,     "src": "/root/.ansible/tmp/ansible-tmp-1584450232.18-80008690840068/source",     "state": "file",     "uid": 0}192.168.100.10 | CHANGED => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": true,     "checksum": "63ff849c6cde8cd1eef04e0472e832d8407eca00",     "dest": "/root/hello.sh",     "gid": 0,     "group": "root",     "md5sum": "c426adca4193658a2183f59d726cc2dc",     "mode": "0644",     "owner": "root",     "size": 58,     "src": "/root/.ansible/tmp/ansible-tmp-1584450232.14-44687748938829/source",     "state": "file",     "uid": 0}node1节点查看:[root@node1 ~]# lltotal 8-rw-------. 1 root root 1557 Sep 28 22:49 anaconda-ks.cfg-rw-r--r--  1 root root   58 Mar 17 21:03 hello.sh删除node节点的hello.sh文件,重新创建个同名文件,再使用ansible复制,如目标存在,默认覆盖,此处backup=yes指定先备份(ansible有幂等性特点)[root@ansible ~]#ansible all -m copy -a 'src=/root/hello.sh dest=/root/ backup=yes mode=+x'    #src:指定源文件 dest:指定目标文件存放目录 backup=yes:如果目标文件存在则进行备份192.168.100.20 | CHANGED => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": true,     "checksum": "63ff849c6cde8cd1eef04e0472e832d8407eca00",     "dest": "/root/hello.sh",     "gid": 0,     "group": "root",     "mode": "0755",     "owner": "root",     "path": "/root/hello.sh",     "size": 58,     "state": "file",     "uid": 0}192.168.100.10 | CHANGED => {    "ansible_facts": {        "discovered_interpreter_python": "/usr/bin/python"    },     "changed": true,     "checksum": "63ff849c6cde8cd1eef04e0472e832d8407eca00",     "dest": "/root/hello.sh",     "gid": 0,     "group": "root",     "mode": "0755",     "owner": "root",     "path": "/root/hello.sh",     "size": 58,     "state": "file",     "uid": 0}[root@ansible ~]#ansible all -a 'ls /root/'192.168.100.20 | CHANGED | rc=0 >>anaconda-ks.cfghello.shhello.sh.4160.2020-03-17@21:14:23~    #原文件存在,被备份jdk-8u221-linux-x64.tar.gz192.168.100.10 | CHANGED | rc=0 >>anaconda-ks.cfghello.shhello.sh.4604.2020-03-17@21:14:22~    #原文件存在,被备份

  5>Fetch模块:从客户端取文件至服务器端,copy相反,目录可先tar

[root@ansible ~]#mkdir /data    #先创建一个/data目录,存放抓取过来的文件[root@ansible ~]#ansible all -m fetch -a 'src=/root/anaconda-ks.cfg dest=/data'192.168.100.10 | CHANGED => {    "changed": true,     "checksum": "c324508ffa651d64f4fa6286fb74ec438e283b3b",     "dest": "/data/192.168.100.10/root/anaconda-ks.cfg",     "md5sum": "b1c0bd6a556fac4e120fddcc7d1124df",     "remote_checksum": "c324508ffa651d64f4fa6286fb74ec438e283b3b",     "remote_md5sum": null}192.168.100.20 | CHANGED => {    "changed": true,     "checksum": "4a2e5b1e34c5496d9dcebbb9a1b7ece8b6b03950",     "dest": "/data/192.168.100.20/root/anaconda-ks.cfg",     "md5sum": "32435d070271e8018672e21ae7c2acbb",     "remote_checksum": "4a2e5b1e34c5496d9dcebbb9a1b7ece8b6b03950",     "remote_md5sum": null}[root@ansible ~]#tree /data//data/├── 192.168.100.10│   └── root│       └── anaconda-ks.cfg└── 192.168.100.20    └── root        └── anaconda-ks.cfg4 directories, 2 files
