在RHEL 7上安装Ansible 2.3
ansible 的用途不解释，之前在CentOS6上安装使用过，因最近大量使用RHEL，所以做个记录，在RHEL7上使用ansible。
第一：安装wget工具
yum install net-tools
yum install wget
第二：安装epel包
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm
yum install epel-release
第三：安装python环境及升级pip
sudo yum install python
sudo yum install python-pip
sudo pip install --upgrade pip
第四：安装ansible
sudo yum install ansible
第五：查看版本
ansible --version
ansible 2.3.1.0
config file = /etc/ansible/ansible.cfg
configured module search path = Default w/o overrides
python version = 2.7.5 (default, Nov 20 2015, 02:00:19) [GCC 4.8.5 20150623 (Red Hat 4.8.5-4)]
测试
# vi /etc/ansible/hosts
[mongo]
10.1.73.6 ansible_ssh_user=root ansible_ssh_pass=123456pass
10.1.73.8 ansible_ssh_user=root ansible_ssh_pass=123456pass
# ansible -m ping mongo
10.1.73.8 | SUCCESS => {
"changed": false,
"ping": "pong"
}
10.1.73.6 | SUCCESS => {
"changed": false,
"ping": "pong"
}
如果遇到以下问题：
10.1.73.8 | FAILED! => {
"failed": true,
"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."
}
解决：在ansible 服务器上使用ssh 登陆下/etc/ansible/hosts 里面配置的服务器（报错的机器）
