相信在大家運(yùn)維的過程中,甲方爸爸的要求那是多種多樣的,掌握些經(jīng)常用到的技術(shù)還是必要的,本篇教學(xué)是本人在一系列痛苦的煎熬后寫出了這篇較為詳細(xì)的ORACLE 11G RAC文檔,根據(jù)本篇教程本人也是部署了很多的生產(chǎn)環(huán)境。閑話少敘,接下來就是正文了。。。。。 本篇涉及到的oracle grid 等軟件包在百度云上,鏈接直接就是下面這個(gè)。 鏈接:https://pan.baidu.com/s/1uty4loIDZlKdi5rRIbIolA 提取碼:n5hw 如果大家在部署的過程中出現(xiàn)問題,可以私信我,不及時(shí)回復(fù)請(qǐng)見諒,畢竟每天還要上班,為甲方爸爸效力。哈哈哈哈
一,硬件環(huán)境 1,1,中標(biāo)麒麟操作系統(tǒng)、兩臺(tái)虛擬主機(jī)。 1,2,IP地址規(guī)劃:管理ip(ip) 2個(gè) 用戶管理集群使用的ip 私有ip (privip) 2個(gè) 用于雙節(jié)點(diǎn)間通訊 業(yè)務(wù)ip(vip) 2個(gè) 業(yè)務(wù)ip,通過訪問scanip后訪問vip 訪問ip(scanip)1個(gè) 對(duì)外表現(xiàn)為業(yè)務(wù)ip 1.3,硬盤規(guī)劃: 一個(gè)仲裁磁盤 OCR_VOTE(可選則三個(gè)) 數(shù)據(jù)磁盤 DATA (tyyw搭建時(shí)劃分了兩個(gè)data在asmca界面組成一個(gè)data組) 閃回磁盤 FRA (700G以下就可以) 1.4 環(huán)境配置 物理主機(jī)需要進(jìn)行bond綁定 最好為4塊網(wǎng)卡分別兩塊網(wǎng)卡一組,兩塊光纖卡需要做冗余bond如下圖。 1.5,如物理主機(jī)劃分存儲(chǔ)lun,則需要安裝多路徑軟件(存儲(chǔ)廠商提供)。 注:多路徑軟件會(huì)發(fā)生fdisk多識(shí)別磁盤現(xiàn)象,注意注意 二,軟件環(huán)境 三,配置hosts 文件 3.1 rac1 注hosts文件不要有大寫出現(xiàn),后期不能識(shí)別 3.2 rac2 #eth0 192.168.8.51 rac1.wln.com rac1 192.168.8.52 rac2.wln.com rac2
