简介

Couchbase 是一个开源的、分布式的、面向文档(document-oriented)的 NoSQL 数据库，并且内置了 Memcached 服务。本文分享的是自己在 Linux 上成功安装 Couchbase Server 的实际操作步骤。

1.下载Couchbase

1.1.登录Couchbase官网, 如下图所示：

1.2.直接下载或者通过wget

[[email protected] dtadmin~]# wget https://packages.couchbase.com/releases/4.6.2/couchbase-server-enterprise-4.6.2-centos7.x86_64.rpm

2.安装包依赖检查

在执行安装之前，确保相应的依赖包已安装。本文通过pkgconfig命令来检查Couchbase Server RPM的依赖。

#安装pkgconfig

[[email protected] ~]# yum -y install pkgconfig

#查看OpenSSL是否安装

[[email protected] ~]# rpm -qa | grep "openssl"

#如果没有安装，用下面命令安装

[[email protected] ~]# yum -y install openssl

3.使用rpm包安装couchbase

[[email protected] dtadmin]# rpm -ivh couchbase-server-enterprise-4.6.2-centos7.x86_64.rpm
