关于yum没有nginx源的问题

问题

解决

cd /etc/yum.repos.d
vim CentOS-Base.repo

Centos6

在尾部添加如下内容

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/6/$basearch/
gpgcheck=0
enabled=1

Centos7

在尾部添加如下内容

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

最后更新

# 清缓存与更新
yum clean all
yum makecache
yum update
# 安装
yum install nginx

关于Ansible的替换脚本

- hosts: all
  remote_user: root
  tasks:
    - name: 更换源
      copy: src=/etc/yum.repos.d/CentOS-Base.repo dest=/etc/yum.repos.d/
      notify:
       - clean mache
       - make mache
    - name: 更新源
      shell: yum update -y
  handlers:
    - name: clean mache
      shell: yum clean all
    - name: make mache
      shell: yum makecache

ansible-playbook -C updateyum.yaml
ansible-playbook updateyum.yaml
ansible all -m shell -a 'cat /etc/yum.repos.d/CentOS-Base.repo'
