Vultr CentOS8 에서 Docker 설치하기 (완전판)

https://ggami.net/638/centos8-docker-%ec%84%a4%ec%b9%98%ed%95%98%ea%b8%b0/ 해당 내용을 이어서 쓰는거이긴 하지만... 그냥 명령어만 작성해놓겠음. 아주 간단하게 Vultr 에서 CentOS8 기준으로 Docker 설치해서 서비스 올려야할때 이거만 보고 따라하면 끝. ``` sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo ``` ``` sudo dnf repolist -v sudo dnf update ``` ``` sudo dnf install docker-ce --nobest docker -v systemctl enable docker ``` ``` curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose docker-compose --version ``` ``` systemctl daemon-reload systemctl restart docker docker info ``` ``` docker run --dns 8.8.8.8 busybox nslookup google.com docker run busybox nslookup google.com nslookup: write to '108.61.10.10': No route to host ;; connection timed out; no servers could be reached ``` ``` docker network create frontend docker network create backend ``` ``` ifconfig br-91b6f0ce06ff: flags=4099 mtu 1500 inet 172.19.0.1 netmask 255.255.0.0 broadcast 172.19.255.255 ether 02:42:fd:cb:c5:6e txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 br-de3921a50a52: flags=4099 mtu 1500 inet 172.18.0.1 netmask 255.255.0.0 broadcast 172.18.255.255 ether 02:42:68:72:5c:0c txqueuelen 0 (Ethernet) RX packets 70967 bytes 219139773 (208.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 48535 bytes 5113144 (4.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 docker0: flags=4099 mtu 1500 inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255 inet6 fe80::42:8fff:fed3:d5b6 prefixlen 64 scopeid 0x20 ether 02:42:8f:d3:d5:b6 txqueuelen 0 (Ethernet) RX packets 4 bytes 196 (196.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10 bytes 852 (852.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ``` ``` firewall-cmd --list-all-zones ``` ``` firewall-cmd --permanent --zone=trusted --add-interface=docker0 firewall-cmd --permanent --zone=trusted --add-interface=br-91b6f0ce06ff firewall-cmd --permanent --zone=trusted --add-interface=br-de3921a50a52 firewall-cmd --reload ``` ``` systemctl restart docker docker run busybox nslookup google.com ``` 이렇게하면... 일단 docker 설치 및 세팅은 끝이난다. (외부접속 아이피 기록 가능) 여기서 추가적으로... docker를 업로드하고서... 명령어를 치면되는데.. ``` docker-compose up -d --build ``` 이렇게.. 빌드할때에 만약에 **composer proc\_open()** 에러가 발생한다면, ``` 스왑생성 free -m /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024 /sbin/mkswap /var/swap.1 /sbin/swapon /var/swap.1 스왑삭제 swapoff /var/swap.1 rm -f /var/swap.1 ``` docker-compose 로 컨테이너를 생성했다면, ``` docker exec -it 69ee26a7c0d4 /bin/bash ``` ``` composer dump-autoload --optimize chgrp -R www-data storage bootstrap/cache chmod -R ug+rwx storage bootstrap/cache php artisan optimize php artisan optimze:clear ``` 끝.
