如果沒有關閉就關閉
systemctl stop firewalld
更新源
ansible -i hosts cache -u root -m shell -a 'yum update -y '
開始安裝
下載Couchbase
[root@couchbase-60 ~]# wget https://packages.couchbase.com/releases/4.6.2/couchbase-server-enterprise-4.6.2-centos7.x86_64.rpm
安裝包依賴檢查
#安裝pkgconfig
ansible -i hosts cache -u root -m shell -a 'yum -y install pkgconfig '
#查看OpenSSL是否安裝
ansible -i hosts cache -u root -m shell -a 'rpm -qa | grep "openssl"'
#如果沒有安裝，用下面命令安裝
[root@apollo ~]# ansible -i hosts cache -u root -m shell -a 'yum -y install openssl'
使用rpm包安裝couchbase
[root@couchbase-60 ~]# rpm -ivh couchbase-server-enterprise-4.6.2-centos7.x86_64.rpm.2

至此，單機版的couchbase安裝成功，後文將持續講解couchbase的集羣與使用。
接下來部署集羣
根據couchbase的安裝經驗，couchbase集羣必須初始化。你可以通過以下方法來初始化couchbase集羣：
- Couchbase的web控制檯 (Couchbase Web Console)
- Couchbase的命令行 (Couchbase Command Line Interface)
- Couchbase的富API接口(Couchbase REST API)
通過界面操作之後，最後啓動couchbase集羣成功的標誌如下：
接下來添加其他機器
下載couchbase軟件包
ansible -i hosts cache -u root -m shell -a 'wget https://packages.couchbase.com/releases/4.6.2/couchbase-server-enterprise-4.6.2-centos7.x86_64.rpm'
