基於ansible的生產環境部署構建(一) 操縱主機簡單部署

簡單說明：

• 本系列記錄使用ansible初始化部署生產環境主機的各項過程
• 本系列生產主機使用《CentOS6實驗機模板搭建部署》和《CentOS6重置網卡克隆後的自適應腳本(二)》預部署，CentOS7系統類似
• 本系列環境需要一臺Gitlab服務器保存ansible代碼和生產項目代碼
• 本系列環境需要一臺Nginx服務器作爲文件共享服務器

操縱主機簡單部署：

• 依據《CentOS7實驗機模板搭建部署》克隆一臺CentOS7作爲操縱主機，部署安裝ansible

HOSTNAME=ansible_ops
hostnamectl set-hostname "$HOSTNAME"
echo "$HOSTNAME">/etc/hostname
echo "$(grep -E '127|::1' /etc/hosts)">/etc/hosts
echo "$(ip a|grep "inet "|grep -v 127|awk -F'[ /]' '{print $6}') $HOSTNAME">>/etc/hosts

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all && yum makecache faster
yum -y install ansible

sed -i '/^#host_key_checking =/ahost_key_checking = False' /etc/ansible/ansible.cfg

• 在Gitlab之上創建一個空項目，下載到操縱主機

yum -y install git
mkdir -p ~/devops && cd ~/devops
cd ~/devops
git config --global http.sslVerify false
git config --global user.email "[email protected]"
git config --global user.name  "vincent"
git clone https://root:vincent%[email protected]:10194/devops/ansible.git
# 密碼爲vincent@123，其中@需要轉譯爲%40

• 創建並部署操縱目錄並配置共享的默認變量文件

WorkDir=~/devops/ansible/os_init
mkdir -pv ${WorkDir}/{inventory,roles,software,pro_mark} && cd ${WorkDir}
cat >defaults_var.yml<<\EOF
