How to intall Soft routing OpenWRT on VMware ESXI

  Others-其他
  • Firstly, we need to download the image file on following link, depend what version you need to use.

ImmortalWRT: More customorized.

OpenWRT: Officinal image

https://firmware-selector.immortalwrt.org/
https://firmware-selector.openwrt.org/
Searched "Generic" then choose the version that compatiable with your device.
  • Then deply the OpenWRT to VMware ESXI. Choose Other 6.x or later Linux (64-bit), Boot type EFI.

The RAM is 512 MB is enough.

  • Then extend the /root/ size according following doc, as even you have extenrd the volume disk to 5 GB, but the size still is about 800 MB.

# Install packages
opkg update
opkg install parted losetup resize2fs blkid

 
# Download expand-root.sh
wget -U "" -O expand-root.sh "https://openwrt.org/_export/code/docs/guide-user/advanced/expand_root?codeblock=0"
 
# Source the script (creates /etc/uci-defaults/70-rootpt-resize and /etc/uci-defaults/80-rootpt-resize, and adds them to /etc/sysupgrade.conf so they will be re-run after a sysupgrade)
. ./expand-root.sh
 
# Resize root partition and filesystem (will resize partiton, reboot resize filesystem, and reboot again)
sh /etc/uci-defaults/70-rootpt-resize

# Resize root partition and filesystem (will resize partiton, reboot resize filesystem, and reboot again)
sh /etc/uci-defaults/70-rootpt-resize

Re-running Script

If the root partition has already been expanded and the expand-root.sh script has previously run, attempting to run it again will not work by default. To perform an additional root expansion, you need remove previous script flags:

rm /etc/rootpt-resize
rm /etc/rootfs-resize

Open the /etc/sysupgrade.conf file and remove the following lines:

/etc/uci-defaults/70-rootpt-resize
/etc/uci-defaults/80-rootfs-resize

This ensures that the system no longer considers the scripts as already executed and then you can re-run script.

  • Enabled https for ImmortalWRT

Step 1: Install necessary software packages

root@ImmortalWrt:~# opkg update
root@ImmortalWrt:~# opkg install luci-ssl-openssl

Step 2: Generate Certificate

#生成私钥和自签名证书（有效期 10 年）

openssl req -x509 -nodes -days 3650 -newkey rsa:2048 \
-keyout /etc/uhttpd.key -out /etc/uhttpd.crt \
-subj "/C=CN/ST=Default/L=Default/O=OpenWrt/CN=OpenWrt"

Modify uHTTPd configuration file

config uhttpd 'main'
	list listen_http '0.0.0.0:80'
	list listen_http '[::]:80'
        list listen_https '0.0.0.0:443'
        list listen_https '[::]:443'
	option redirect_https '1'
	option home '/www'
	option rfc1918_filter '1'
	option max_requests '50'
	option max_connections '100'
	option cert '/etc/uhttpd.crt'
	option key '/etc/uhttpd.key'
	option cgi_prefix '/cgi-bin'
	list lua_prefix '/cgi-bin/luci=/usr/lib/lua/luci/sgi/uhttpd.lua'
	option script_timeout '60'
	option network_timeout '30'
	option http_keepalive '20'
	option tcp_keepalive '1'
	option ubus_prefix '/ubus'

config cert 'defaults'
	option days '397'
	option key_type 'ec'
	option bits '256'
	option ec_curve 'P-256'
	option country 'ZZ'
	option state 'Somewhere'
	option location 'Unknown'
	option commonname 'ImmortalWrt'

Then using https://192.168.2.1 (You WRT IP address) to access

  • Install Passwll service
root@ImmortalWrt:~# opkg update
root@ImmortalWrt:~# opkg install luci-app-passwall luci-i18n-passwall-zh-cn

After installed completed, you can check the Passwall service in Service menu.

  • Install components to monitor the traffic usage for ImmortalWRT.
root@ImmortalWrt:~# opkg update
root@ImmortalWrt:~# opkg list | grep vnstat
opkg install vnstat2 luci-i18n-vnstat2-zh-cn
root@ImmortalWrt:~# /etc/init.d/vnstat enable
root@ImmortalWrt:~# /etc/init.d/vnstat start

Config the monitoring port “br-lan”

If there is any traffic data, it will show here.

RX (Receive): 接收流量

含义：指从外部进入该接口（如 br-lan）的数据。

对应你的场景：通常代表下载。比如你在手机上刷视频、下软件，路由器接收并转发给你的数据量。

TX (Transmit): 发送流量

含义：指从该接口发出去的数据。

对应你的场景：通常代表上传。比如你把照片发到朋友圈、同步云盘或视频通话时发送的数据量。

简单理解：

TX = 出去的数据（Upload）

RX = 进来的数据（Download）
