為 RT-AC56U 安裝 Entware

為 RT-AC56U 安裝 Entware

完整說明請參考這篇.

這裡配合的 firmware 是 Asuswrt-merlin 384.6_0 版.

首先, 準備一個 USB stick 或是 SD card + reader, 然後建立 partition 並且 format 成 ext2, 是的, ext2.

接著, 插上 RT-AC56U 後方的 USB port, 在 web 管理界面開啟 ssh 服務, ssh 上去, 並 mount 剛插上的 USB stick 到以下位置 (如果只插了一根 USB stick, 那 disk 的 device node 應該為 /dev/sda, 第一個 partition 的 device node 則為 /dev/sda1)

$ ssh [email protected]
[email protected]:/tmp/home/root# mkdir -p /tmp/mnt/sda1
[email protected]:/tmp/home/root# mount /dev/sda1 /tmp/mnt/sda1

接著, 直接執行 firewmare 中的 script 初始 Entware, 會立即跟你確認 Entware 放置的位置

[email protected]:/tmp/home/root# entware-setup.sh
 Info:  This script will guide you through the Entware installation.
 Info:  Script modifies "entware" folder only on the chosen drive,
 Info:  no other data will be changed. Existing installation will be
 Info:  replaced with this one. Also some start scripts will be installed,
 Info:  the old ones will be saved on Entware partition with name
 Info:  like /tmp/mnt/sda1/jffs_scripts_backup.tgz

 Info:  Looking for available partitions...
[1] --> /tmp/mnt/sda1
 =>  Please enter partition number or 0 to exit
[0-1]: 1
 Info:  /tmp/mnt/sda1 selected.

接下來會下載一些 package 提供 package 管理功能

 regexp could be something like 'pkgname*' '*file*' or similar
 e.g. opkg info 'libstd*' or opkg search '*libop*' or opkg remove 'libncur*'

例如, 我們想把 shell 改成 bash, 確認下是否有這個 package

[email protected]:/tmp/home/root# opkg list | grep bash
bash - 4.4.18-1 - Bash is an sh-compatible command language interpreter that executes commands read from the standard input or from a file. Bash also incorporates useful features from the Korn and C shells (ksh and csh).
