ansible进阶

使用源码安装Python3.5

安装支持包

[root@ansible ~]# yum -y install lrzsz vim net-tools gcc gcc-c++ ncurses ncurses-devel unzip zlib-devel zlib openssl-devel openssl

源码编译Python3.5

[root@ansible Python-3.5.2]# tar xf Python-3.5.2.tgz -C /usr/src/
[root@ansible Python-3.5.2]# cd /usr/src/Python-3.5.2/
[root@ansible Python-3.5.2]# ./configure --prefix=/usr/local/python/
[root@ansible Python-3.5.2]# make && make install
[root@ansible Python-3.5.2]# ln -s /usr/local/python/bin/python3 /usr/bin/python3
[root@ansible Python-3.5.2]# which python3
/usr/bin/python3
[root@ansible Python-3.5.2]# python3 -V
Python 3.5.2

使用pip3安装ansible

安装ansible最新版本

[root@ansible Python-3.5.2]# /usr/local/python/bin/pip3 install ansible

ansible安装完毕后

[root@ansible python]# ln -s /usr/local/python/bin/ansible /usr/local/bin/
[root@ansible python]# which ansible
/usr/local/bin/ansible
[root@ansible python]# ansible --version
ansible 2.5.4
  config file = None
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/python/lib/python3.5/site-packages/ansible
  executable location = /usr/local/bin/ansible

生成密钥对

[root@ansible python]# ssh-keygen -t rsa -f ~/.ssh/id_rsa -P “”

分发密钥

[root@ansible python]# ssh-copy-id -i ~/.ssh/id_rsa.pub “-o StrictHostKeyChecking=no” 192.168.163.136

进行免密码登陆测试

[root@ansible python]# ssh 192.168.200.132

ansible的配置文件

[root@ansible python]# mkdir -p /etc/ansible
[root@ansible python]# vim /etc/ansible/hosts
[root@ansible python]# cat /etc/ansible/hosts   #ansible主机管理配置文件
[nginx]         #被管理的主机组名称
webA ansible_ssh_host=192.168.163.136 ansible_ssh_port=22 ansible_ssh_user=root #第一台主机
webB ansible_ssh_host=192.168.163.146 ansible_ssh_port=22 ansible_ssh_user=root  ansible_ssh_pass=111111    #第二台主机

下载epel源安装sshpass

[root@ansible python]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@ansible python]# yum -y install sshpass
[root@ansible python]# which sshpass
/usr/bin/sshpass
