1. This article mainly introduces some configuration in the server during the react+ Egg project construction, which is convenient for direct operation later

2. It mainly adopts the way of Docker to integrate Jenkins automatic deployment, mysql, Redis and so on.

3. It has to be said that the use of Docker greatly reduces the front-end operation of the server environment, making it convenient to get started and rapidly deploy services

1.Docker installation

1.1, install,

 sudo yum remove docker \
                  docker-client \

sudo curl -L "Https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s) - $(uname -m)"Docker-compose -o /usr/local/bin/docker-compose -o /usr/local/bin/docker-compose -o /usr/local/bin/docker-compose -o /usr/local/bin/docker-compose -o /usr/local/bin/docker-composeCopy the code

4. Install node

The node to download

Upload the file and unzip it

  1. Uploading the Compressed package You can use some software to upload the downloaded NodeJS compressed package (current version: Node-v14.16.1-linux-x64.tar. xz) to any location on the server. It can be /usr/local/src.
  2. Decompress the package:The tar XVF - node - v14.16.1 - Linux - x64. Tar. XzDecompress the package
  3. Decompressed file rename command:Node - mv v14.16.1 - Linux - x64 nodejs
  4. Check file directory integrity: check whether node, NPM, NPX exist. If no, run the preceding command again.

Global references

  1. Creating a Soft connection
ln -s /usr/local/src/nodejs/bin/npm /usr/local/bin
ln -s /usr/local/src/nodejs/bin/node /usr/local/bin
Copy the code

Note: / usr/local/SRC/nodejs this address for installation/bin/NPM nodejs files under the absolute address of NPM and the node location, according to each person is different. Run the node -v command to check whether the command takes effect globally. If the version number is displayed, it indicates success.

5, install mysql
