使用ansible-playbook批量部署Nginx-web 集群服务
使用ansible-playbook批量部署Nginx-web 集群服务
所有操作在 jumpserver上进行
1. 先上拓扑图
2. 配置jumpserver
配置 基本环境
mkdir -p /etc/yum.repos.d/repo_bak/
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/repo_bak/
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.myhuaweicloud.com/repo/CentOS-Base-7.repo
yum repolist
yum -y install bash-completion lrzsz
配置免密登录其他主机
ssh-keygen -f /root/.ssh/id_rsa -N ''
ssh-copy-id root@主机ip
配置DNS服务 （内网中同步/etc/hosts 文件，可以不需要）
暂不配置，使用/etc/hosts文件
配置vsftp服务和提供yum源 , 把local.repo同步到其他主机
yum -y install vsftpd
yum -y install createrepo
mkdir -p /var/ftp/localrepo
cd /var/ftp/localrepo
createrepo .
systemctl restart vsftpd
systemctl enable vsftpd
vim /etc/yum.repos.d/local.repo
[local_repo]
name=local - Base
baseurl="ftp://192.168.1.100/localrepo/"
enabled=1
gpgcheck=0
配置ansible服务
yum -y install ansible
3. 制做Nginx的RPM包
安装RPM-build软件包
yum -y install rpm-build
生成rpmbuild目录结构
rpmbuild -ba nginx.spec
把家目录下的Nginx源码包(需要提前准备nginx源码包)复制到SOURCES下
cp ~/nginx-1.12.2.tar.gz ~/rpmbuild/SOURCES/
家目录下创建nginx.service ，方便制作的RPM包能用系统管理相应服务
vim ~/nginx.service
[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
创建并修改SPEC配置文件
vim ~/rpmbuild/SPECS/nginx.spec
Name:nginx
Version:1.12.2
Release:10
Summary:nginx web server software
Group:nginx
License:GPL
URL:www.test.com
Source0:nginx-1.12.2.tar.gz
#BuildRequires:
#Requires:
%description
nginx [engine x] is an HTTP and reverse proxy server.
%post
useradd -s /sbin/nologin nginx
%prep
%setup -q
%build
./configure --user=nginx --group=nginx
make %{?_smp_mflags}
%install
make install DESTDIR=%{buildroot}
mkdir -p %{buildroot}/lib/systemd/system
cp /root/nginx.service %{buildroot}/lib/systemd/system/
%files
%doc
/usr/local/nginx/*
/lib/systemd/system/nginx.service
%changelog
安装依赖包
yum -y install gcc pcre-devel openssl-devel
生成RPM包
rpmbuild -ba ~/rpmbuild/SPECS/nginx.spec
查看生成的RPM包
ls ~/rpmbuild/RPMS/x86_64/
把RPM包发送到 jumpserver 的RPM仓库 (修改 jumpserver 的对应 IP )
cp ~/rpmbuild/RPMS/x86_64/nginx-1.12.2-10.x86_64.rpm /var/ftp/localrepo/
更新RPM包仓库信息
cd /var/ftp/localrepo/
createrepo --update .
4. Nginx_web集群
修改本地/etc/hosts 并同步到其他elasticsearch主机
vim /etc/hosts
192.168.1.100 ecs-jump-server
192.168.1.51 ecs-web-0001
192.168.1.52 ecs-web-0002
192.168.1.53 ecs-web-0003
192.168.1.54 ecs-web-0004
192.168.1.55 ecs-web-0005
192.168.1.56 ecs-web-0006
192.168.1.57 ecs-web-0007
192.168.1.58 ecs-web-0008
for i in ecs-web-000{1..8}
do
scp /etc/hosts ${i}:/etc/
done
准备nginx配置文件 nginx.conf
请自行准备
准备web的测试页面文件
index.html文件，自行准备
准备ansible运行环境
vim ansible.cfg
[defaults]
inventory = hosts
host_key_checking = False
vim hosts
[web]
ecs-web-0001
ecs-web-0002
ecs-web-0003
ecs-web-0004
ecs-web-0005
ecs-web-0006
ecs-web-0007
ecs-web-0008
#[all:vars]
#ansible_ssh_private_key_file='/root/.ssh/key'
创建 nasible-playbook 文件
vim nginx_setup.yaml
---
- hosts: web
remote_user: root
tasks:
- name: install Nginx
yum:
name: "{{item}}"
state: installed
with_items:
- nginx
- copy:
src: index.html
dest: /usr/local/nginx/html/index.html
owner: root
group: root
mode: 0644
- template:
src: nginx.conf
dest: /usr/local/nginx/conf/nginx.conf
owner: root

notify: reload nginx
tags: nginxconf
- service:
name: nginx
enabled: yes
