STM32 Bluepill dan Arduino IDE di Ubuntu

Kali ini saya akan sharing mengenai cara menggunakan arduino IDE di STM32 Bluepill ok langsung saja begini caranya.

1. Pastikan sudah memiliki stm32 bluepill
2. Pastikan sudah menginstall arduino IDE
3. Masuk ke board manager lalu install Arduino SAM Boards (32 bit ARM Cortex M3)
4. Download library disini lalu unzip kemudian copykan foldernya ke dalam hardware di Arduino IDE
5. Karena kita menggunakan ubuntu sebagai OS maka kita harus menginstall beberapa library yang sudah disediakan, caranya masuk ke hardware lalu ke Arduino_STM32 yang tadi kita masukkan lalu ke tools dan kemudian ke folder linux setelah itu klik kanan lalu klik open in terminal.
6. Setelah terminal terbuka lalu ketikkan ./install.sh kemudian tinggal diikuti saja perintahnya dan selesai .
7. Agar kita bisa upload via usb maka kita perlu memflash stm32 bluepill menggunakan firmware maple mini

Mysql ERROR 1698 (28000) root@localhost access denied

Sedikit share kalau ada yang mengalami hal yang serupa, tiba tiba saja mysql ngambek ngga bisa diakses setelah diinstall.

masuk ke mysql menggunakan sudo

sudo mysql -u root

ganti password mysql

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'new-password';

restart mysql service

sudo service mysql stop
sudo service mysql start

Done selesai coba akses kembali

kalau ngga bisa juga coba cara disini 

Docker compose nginx

Catatan setup nginx di docker supaya bisa ngeload volume diluar file directorynya docker

Buat docker-compose.yml isikan baris perintah dibawah

version: '2'

services:

nginx:

image: nginx:latest

container_name: production_nginx

volumes:

- /home/onix/sites:/usr/share/nginx/html:z #directory internal:directory docker

ports:

- '8080:80'

Udah gitu aja mudah bukan

Happy Coding ..

Docker manager web based

Docker manager mantap via web base lagi yang penasaran silahkan ke sini https://portainer.io/ dan kerennya lagi si portainernya juga bisa dijalankan lewat docker ngga perlu install manual cool right !.

docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer

Happy Coding …

install odoo menggunakan docker

Ada yang belum kenal odoo baca disini ya https://www.odoo.com/  ya odoo adalah open source ERP dan CRM, kedua aplikasi ini banyak digunakan untuk perusahaan untuk memanage jalannya operasional perusahaan, modulnya banyak banget dari HR, Project Management, Procurement, dll, bagi yang penasaran silahkan baca baca sendiri di websitenya odoo ya.

Kali ini saya akan sharing bagaimana caranya menginstall odoo dengan menggunakan docker caranya cukup mudah tinggal siapkan OS yang akan diinstall kemudian install docker (cari digoogle ttg cara install docker) kemudian silahkan baca dokumentasinya disini https://hub.docker.com/_/odoo/.

Untuk kali ini saya menginstall docker menggunakan OS ubuntu server, caranya gampang banget pertama tama git clone link berikut https://github.com/odoo/docker kemudian masuk ke folder versi docker yang sudah tersedia untuk kali ini saya menggunakan versi 11 karena pada saat tulisan ini dibuat versi 12 baru saja release jadi amannya pake versi sebelumnya dulu.

Setelah memilih versi odoo (saya menggunakan versi 11) tinggal jalankan command ini

docker run -d -e POSTGRES_USER=odoo -e POSTGRES_PASSWORD=odoo --name db postgres:9.4

docker run -p 8069:8069 --name odoo --link db:db -t odoo

Udah gitu aja 🙂 mudah bukan saya menyarankan ubah nama user dan password pada saat menjalankan db dibagian POSTGRES_USER dan POSTGRES_PASSWORD setelah diinstall silahkan buka browser lalu masukkan alamat ip dilanjutkan dengan nomor port contoh http://localhost:8069 atau ganti localhost dengan nomor ip sobat sekalian.

kalau ngga mau ribet masukkan port bisa juga dengan menambahkan ip tables seperti ini di

/etc/rc.local diatas exit

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8069

Setelah reboot maka odoo bisa diakses menggunakan ip tanpa port

Silahkan mencoba dan happy coding …
