This article mainly introduces the example analysis of the deployment of the Ubuntu environment in SpringCloud, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

Deployment of SpringCloud-related environment

RabbitMQ deployment Redis deployment Nacos deployment

RabbitMQ

Apt-get install is not installed as an update installation package. Download the corresponding version of the installation package from the official website and install it by command.

Before installing RabbitMQ, you need the support of the Erlang environment and download the corresponding Erlang version of the package.

Erlang

To avoid version conflicts, I first deleted the previous erlang environment, apt-remove erlang, but cleaned it up completely.

Delete erlang under Ubuntu

1.which erl2.sudo rm-rf / usr/bin/erl3.sudo rm-rf / usr/lib/erlang

Then install the corresponding version of the erlang package

Dpkg-I installation package. Deb

View erlang version sudo erl

Install RabbitMQ

Official website: www.rabbitmq.com/install-deb.

Download the RabbitMQ package: packagecloud.io/rabbitmq/ra …

Dpkg-I RabbitMQ.deb

Problems encountered in the installation:

1. RabbitMQ startup error:-unable to connect to epmd on xxxx: timeout (timed out). Solution: sudo vi / etc/hosts, add 127.0.0.1 example,example as RabbitMQ instance

Root@example:/var/lib/rabbitmq# cd mnesia/root@example:/var/lib/rabbitmq/mnesia# lsrabbit@example rabbit@example-feature_flags rabbit@example.pid rabbit@example-plugins-expand

Add ports to Aliyun. Local access: localhost:15672. You can add guest/guest by default. For security reasons, remote access guest does not take effect by default. Need to add an additional user, rabbitmqctl add_user username and password.

To enter the management interface, you need to activate Access permissions for users.

Redis

Download the installation package: Redis official website redis.io/download

Extract it to the / usr/lcoal directory, go to the bin directory. / redis-server, start the server and

Connect to the client, execute. / redis-client in the bin directory, and start the client

Problems encountered 1. Problems with temporary startup and permanent startup after changing the password. Solution: temporary startup using command mode

Sudo redis-cli-p 637 password whether to set password command sudo config get requirepass# set password command sudo config set requirepass 12345 verify password sudo auth password

2. Permanent effective mode

After entering the redis.conf file, find the requirepass parameter, set the password, and restart the service.

3. Backend activation takes effect.

Sudo / user/local/redis/binsudo / redis-server. / redis.conf

Nacos

Install in the way of installation package

The only thing to pay attention to is that under the Ubuntu environment, the bash command is used to install.

Bash-f. / startup.sh-m standalone
