Juniper 模擬器 JUNOS 升級指南

Maa 2007-8-19 NJ

對VMWare虛擬機下的Juniper模擬器進行軟件版本升級，從版本8.1R1.5升級到版本8.3R2.8。

升級準備

VMware 5.5模擬器軟件：運行版本8.1R1.5的JUNOS；

Named Pipe TCP Proxy軟件：提供終端控制檯和模擬器之間的登錄方式；

終端控制檯：登錄模擬器，通用的終端控制檯便可；

WFTPD：提供ftp server功能；

待升級版本：jinstall-8.3R2.8-export-signed.tgz。

首先打開VMWare的模擬器，將其中的一塊網卡和虛擬網卡關聯起來，這樣模擬器就能夠經過該虛擬網卡和windows操做系統通訊了，以下圖所示，我將模擬器的網卡和虛擬網卡VMnet2關聯起來：

同時配置VMnat2的ip地址以下圖所示：

而後啓動WFTPD軟件，並設置好相關的用戶賬號，並將待升級文件拷貝到用戶賬號指定的目錄下，以下圖所示：

這樣，升級前準備工做就完成了。

啓動Named Pipe TCP Proxy和虛擬機，並經過終端登錄上Juniper的模擬器，詳細內容能夠參考文檔《Juniper模擬器使用指南》，此處略過。

Juniper模擬器啓動完畢後，經過下面的命令咱們能夠看到當前的JUNOS版本仍是8.1R1.5。

這時退出模擬器的cli模式，將當前目錄切換到/var/tmp下，通常都習慣於將升級文件統一下載到這個目錄下，這只是一個習慣，你們能夠根據本身的實際狀況選擇存放JUNOS升級文件的目錄，而後經過ftp方式訪問VMnet2網卡，並下載jinstall-8.3R2.8-export-signed.tgz文件到虛擬機的操做系統上，以下所示：

root@R1> exit /* 退出 cli 模式 */

root@R1% pwd /* 顯示當前目錄 */

root@R1% cd /var/tmp/ /* 切換當前目錄到 /var/tmp/ 下 */

此時進入JUNOS的cli模式，經過命令添加升級文件包，該添加過程會對整個升級文件進行一系列的檢查，好比CRC校驗、版本一致性對比、配置文件一致性對比等等，以下所示：

root@R1% cli /* 進入 JUNOS 的 cli 模式 */

root@R1> request system software add /var/tmp/jinstall-8.3R2.8-export-signed.tgz force

/* 添加升級文件包，下面顯示的內容爲執行該命令後的輸出信息 */

至此整個升級文件的添加過程就進行完畢了，此時須要重啓JUNOS，重啓以後就完成了整個軟件版本的升級過程，經過以下命令重啓JUNOS：

root@R1> request system reboot /* 重啓 JUNOS ，後面不粘貼重啓過程的詳細輸出，不必 */

Reboot the system ? [yes,no] (no) yes

Shutdown NOW!

能夠看到，JUNOS已經成功升級到8.3R2.8版本，先寫到這吧，由於是本身第一次升級JUNOS的軟件版本，寫個文檔記錄一下升級的關鍵步驟，接下來會琢磨一下新版本的特性是否有本身用的上的地方。
