Each site runs its own air. One per folder. Each air watches only its own folder if you add .air.toml.

The rule

text

~/CMS/ai/               → runs its own air on port 8080
~/CMS/officialstupid-me → runs its own air on port 8081
~/CMS/anything-else     → runs its own air on port 8082

One terminal per site. Each cd into its folder, each runs air.

Step 1 — Add .air.toml to every site

In each site folder:

bash

cd ~/CMS/ai
cat > .air.toml <<'EOF'
root = "."
tmp_dir = "tmp"

[build]
cmd = "go build -o ./tmp/cms main.go"
bin = "./tmp/cms"
include_ext = ["go", "html", "css", "js"]
exclude_dir = ["tmp", "uploads", "node_modules", ".git"]
delay = 200
stop_on_error = true
send_interrupt = false
kill_delay = "500ms"

[log]
time = true
main_only = true
EOF

Do the same for officialstupid-me.

Step 2 — Change the port per site

Currently both sites default to 127.0.0.1:8080. They will conflict.

Edit main.go in each site. Find:

go

Addr:              "127.0.0.1:8080",

Change to use an env variable:

go

addr := os.Getenv("CMS_ADDR")
if addr == "" {
    addr = "127.0.0.1:8080"
}

And in the srv := &http.Server{...} block:

go

Addr:              addr,

Do that once per site. Then start each with a different port.

Step 3 — Run each site on its own port

Terminal 1:

bash

cd ~/CMS/ai
CMS_ADDR=127.0.0.1:8080 air

Terminal 2:

bash

cd ~/CMS/officialstupid-me
CMS_ADDR=127.0.0.1:8081 air

Browser:

• http://127.0.0.1:8080/ → ai site
• http://127.0.0.1:8081/ → officialstupid-me

Both run at the same time. Completely isolated.

Step 4 — Clean up stray build artifacts

Your tree shows tmp/cms and tmp/main in both sites. Those are from air. tmp/ is safe to delete anytime — air will recreate it.

bash

rm -rf ~/CMS/ai/tmp ~/CMS/officialstupid-me/tmp

Also ~/CMS/ai/data.db-shm and data.db-wal are runtime files that travel with data.db. Keep them.

Step 5 — What to keep vs delete per site

Keep (per site):

• main.go, go.mod, go.sum
• templates/, static/, uploads/
• data.db, data.db-shm, data.db-wal
• .password_hash (if it exists)
• .air.toml

Delete or ignore:

• tmp/ (build cache — auto-created)
• cms binary in the root (leftover)
• main.7z and main-good.7z — your personal backups, up to you

Step 6 — Template for future sites

Make one clean template folder to clone from.

bash

cd ~/CMS
mkdir -p _template
cp ai/main.go _template/
cp ai/go.mod _template/
cp ai/go.sum _template/
cp -r ai/templates _template/
cp -r ai/static _template/
cp ai/.air.toml _template/

To start a new site:

bash

cd ~/CMS
cp -r _template new-site
cd new-site
mkdir -p uploads
# edit main.go: change defaultPassword, add CMS_ADDR env, change site title in base.html
CMS_ADDR=127.0.0.1:8082 air
