一、配置apache

1、首先在角色中手动定义三个服务角色

[student@server roles]$ ansible-galaxy init apache
- Role apache was created successfully
[student@server roles]$ ansible-galaxy init mysql
- Role mysql was created successfully
[student@server roles]$ ansible-galaxy init php
- Role php was created successfully
[student@server roles]$ cd apache/
//这次服务主要用到的模块
[student@server apache]$ tree 
.
├── defaults
│   └── main.yml
├── files       //用于存放软件包和脚本
├── handlers
│   └── main.yml
├── meta
│   └── main.yml
├── README.md
├── tasks     //用于存放play主模块
│   └── main.yml
├── templates   //用于写入启动服务的j2文件
├── tests
│   ├── inventory
│   └── test.yml
└── vars         //用于定义需要下载的服务名
    └── main.yml

8 directories, 8 files

2、定义files中的脚本

首先定义好yum源地址

[student@server files]$ cat yum.sh 
#!/bin/bash
/usr/bin/curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
yum reinstall -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
/usr/bin/sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
/usr/bin/sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*

定义预编译程序
预编译三部曲

[student@server files]$ cat apache.sh 
#!/bin/bash
cd /opt/apr-1.7.0
sed -i '/$RM "$cfgfile"/d' configure
./configure --prefix=/usr/local/apr
make
make install

cd /opt/apr-util-1.6.1
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
make
make install

cd /opt/httpd-2.4.54
./configure --prefix=/usr/local/apache \\
	--sysconfdir=/etc/httpd24 \\
	--enable-so \\
	--enable-ssl \\
	--enable-cgi \\
	--enable-rewrite \\
	--with-zlib \\
	--with-pcre \\
	--with-apr=/usr/local/apr \\
	--with-apr-util=/usr/local/apr-util/ \\
	--enable-modules=most \\
	--enable-mpms-shared=all \\
	--with-mpm=prefork
make
make install

定义环境变量

[student@server files]$ cat httpd.sh 
echo 'export PATH=/usr/local/apache/bin/:$PATH' > /etc/profile.d/httpd.sh
source /etc/profile.d/httpd.sh

3、定义清单任务模块


[student@server apache]$ cat tasks/main.yml 
---
# tasks file for apache
- name stop firewalld     ——关闭防火墙
  service: 
    name: firewalld
    state: stopped
    enabled: no

- name: stop selinux    ——永久关闭
  lineinfile: 
    path: /etc/selinux/config
    regexp: '^SELINUX='
    line: SELINUX=disabled

- name: stop selinux1    ——关闭防火墙并加载
  shell: 
    cmd: setenforce 0

- name: set yum        ——指定file中定义的yum源脚本
  script: yum.sh

- name: install pkgs   ——下载所需的安装环境
  shell: 
    cmd: yum -y install bzip2  vim make wget openssl-devel pcre-devel expat-devel libtool gcc gcc-c++ libxml2-devel --allowerasing

- name: unzip       ——解压缩到/opt下
  unarchive: 
    src: apr-1.7.0.tar.gz
    dest: /opt/

- name: unzip
  unarchive: 
    src: apr-util-1.6.1.tar.gz
    dest: /opt/

- name: unzip
  unarchive: 
    src: httpd-2.4.54.tar.gz
    dest: /opt/


- name: cr apache      ——创建系统用户
  user: 
    name: apache
    system: yes
    shell: /sbin/nologin
    create_home: no
    state: present

- name: apache.sh      ——执行预编译脚本
  script: apache.sh

- name: httpd.sh      ——环境变量脚本
  script: httpd.sh

- name: cp config     ——调用system服务
  template: 
    src: httpd.service.j2
    dest: /usr/lib/systemd/system/httpd.service

- name: apply config   ——重启系统服务
  shell: 
    cmd: systemctl daemon-reload

- name: restart httpd    ——开启服务
  service: 
    name: httpd
    state: started
    enabled: yes

定义system服务启动

[student@server templates]$ cat httpd.service.j2 
[Unit]
Description=httpd server daemon
After=network.target 
[Service]
Type=forking
ExecStart=/usr/local/apache/bin/apachectl start
ExecStop=/usr/local/apache/bin/apachectl stop
ExecReload=/bin/kill -HUP $MAINPID
[Install]
WantedBy=multi-user.target

创建用户

[student@server ansible]$ cat apache.yml 
---
- name: use apache role
  hosts: node1
  roles: 
    - apache

4、执行apache—playbook任务

[student@server ansible]$ ansible-playbook apache.yml

PLAY [use apache role] *********************************************************

TASK [Gathering Facts] *********************************************************
ok: [node1]

TASK [apache : stop firewalld] *************************************************
ok: [node1]

TASK [apache : stop selinux] ***************************************************
ok: [node1]

TASK [apache : set yum] ********************************************************
changed: [node1]

TASK [apache : install pkgs] ***************************************************
changed: [node1]

TASK [apache : unzip] **********************************************************
ok: [node1]

TASK [apache : unzip] **********************************************************
ok: [node1]

TASK [apache : unzip] **********************************************************
changed: [node1]

TASK [cr apache] ***************************************************************
ok: [node1]

TASK [apache.sh] ***************************************************************
changed: [node1]

TASK [apache : httpd.sh] *******************************************************
changed: [node1]

TASK [apache : cp config] ******************************************************
changed: [node1]

TASK [apache : apply config] ***************************************************
changed: [node1]

TASK [apache : restart httpd] **************************************************
ok: [node1]

PLAY RECAP *********************************************************************
node1                      : ok=14   changed=7    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

查看node1IP地址是否访问成功

二、配置MySQL

1、主任务模块

[student@server mysql]$ cat tasks/main.yml 
---
# tasks file for mysql
- name: create user mysql     ——设置用户
  user: 
    name: mysql
    system: yes
    shell: /sbin/nologin
    create_home: no
    state: present

- name: install pkgs   ——安装依赖包
  yum: 
    name: "libncurses*"
    state: present

- name: unzip
  unarchive: 
    src: mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz
    dest: /usr/local/

- name: create link     ——设置软链接
  file: 
    src: /usr/local/mysql-5.7.37-linux-glibc2.12-x86_64
    dest: /usr/local/mysql
    owner: mysql
    group: mysql
    state: link

- name: create data ml   ——设置工作目录
  file: 
    path: /opt/data
    owner: mysql
    group: mysql
    state: directory

- name: mysql-csh.sh  ——数据库初始化
  script: mysql-csh.sh

- name: cp config   ——数据库服务位置
  template: 
    src: my.cnf.j2
    dest: /etc/my.cnf

- name: replace file1     ——使其sql服务访问
  replace: 
    path: /usr/local/mysql/support-files/mysql.server
    regexp: "#^(basedir=).*"
    replace: "basedir=/usr/local/mysql"

- name: replace file2
  replace: 
    path: /usr/local/mysql/support-files/mysql.server
    regexp: "#^(datadir=).*"
    replace: "datadir=/opt/data"

- name: cp mysqld.service
  template: 
    src: mysqld.service.j2
    dest: /usr/lib/systemd/system/mysqld.service

- name: apply config
  shell: 
    cmd: systemctl daemon-reload

- name: restart mysqld
  service: 
    name: mysqld
    state: started
    enabled: yes

- name: set mysql passwd   ——设置密码
  shell: 
    cmd: /usr/local/mysql/bin/mysql -uroot -e "set password=password('$redhat')"

- name: set mysql env      ——环境变量
  script: mysqlbl.sh

2、file脚本环境变量

//软件包

[student@server files]$ ls
mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz

数据库初始化

[student@server files]$ cat mysql-csh.sh 
#!/bin/bash
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --datadir=/opt/data/
ln -sv /usr/local/mysql/include/ /usr/local/include/mysql
echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf
ldconfig

//环境配置

[student@server files]$ cat mysqlbl.sh 
echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile.d/mysql.sh
source /etc/profile.d/mysql.sh

3、templates定义模具

定义数据库工作对象

[student@server mysql]$ cat templates/my.cnf.j2 
[mysqld]
basedir = /usr/local/mysql
datadir = /opt/data
socket = /tmp/mysql.sock
port = 3306
pid-file = /opt/data/mysql.pid
user = mysql
skip-name-resolve

配置启动服务文件

[student@server mysql]$ cat templates/mysqld.service.j2 
[Unit]
Description=mysql server daemon
After=network.targe

[Service]
Type=forking
ExecStart=/usr/local/
基于ansible role实现LAMP平台批量部署


 


 

 
 
前言
 
 
作为运维人员，当面对几十台或上百台服务器需要修改某个参数或部署某个平台，你将从何入手呢？ansible的出现很好的解决了这一困扰，ansible基于Python开发，集合了众多运维工具（puppet、cfengine、chef、func、fabric）的优点，实现了批量系统配置、批量程序部署、批量运行命令等功能。本文带来的是基于Ansible Role实现LAMP平台批量部署。
 
 
ansible简介
 
 
特性
 
 

 
 
     
  
  • No agents：不需要在被管控主机上安装任意客户端
    •  
  
  • No server：无服务器端，使用时直接运行命令即可
    •  
  
  • Modules in any languages：基于模块工作，可使用任意语言开发模块
    •  
  
  • YAML，not code：使用yaml语言定制剧本playbook
    •  
  
  • SSH by default：基于SSH工作
    •  
  
  • Strong multi-tier solution：可实现多级指挥
    •
