cloud init local 开机时间长和无法获取元数据

在 /etc/netsvc.conf 里面添加一行

hosts=local4

结束时应用
datasource:
  Ec2:
    timeout: 5
    max_wait: 10
但它根本不起作用，超时仍为50秒，max_wait为120秒。 我的操作系统Red Hat 6，cloud-init版本：0.7.4

# Force only Ec2 being enabled
datasource_list: ['Ec2']
datasource:
  Ec2:
    metadata_urls: [ 'http://169.254.169.254' ]
    timeout: 5 # (defaults to 50 seconds)
    max_wait: 10 # (defaults to 120 seconds)
EOF

# Remove default datasource_list
rm -f /etc/cloud/cloud.cfg.d/90_dpkg.cf

apt-get -y install pump cloud-utils cloud-init cloud-initramfs-growroot 
    bash-completion

# Speed up cloud-init by only using Ec2 and a specific metadata url
cat >> /etc/cloud/cloud.cfg.d/91_Ec2_override.cfg << EOF

# Force only Ec2 being enabled
datasource_list: ['Ec2']
datasource:
  Ec2:
    metadata_urls: [ 'http://169.254.169.254' ]
    timeout: 5 # (defaults to 50 seconds)
    max_wait: 10 # (defaults to 120 seconds)
EOF

# Remove default datasource_list
rm -f /etc/cloud/cloud.cfg.d/90_dpkg.cfg

 

 

进入系统后修改文件/etc/systemd/system/network-online.target.wants/networking.service

命令：sudo vim /etc/systemd/system/network-online.target.wants/networking.service

将里面的TimeoutStartSec=5min 修改为TimeoutStartSec=2sec

然后重启系统，就可以生效了，开机速度很快。
