There is a pit ahead---------If you operate the firewall [start or stop] during docker running, you must restart

docker systemctl restart docker

edit configuration file

vi /etc/docker/daemon.json

Copy the following content in /etc/docker/daemon.json

{ "registry-mirrors":
["https://32xw0apq.mirror.aliyuncs.com"] }
systemctl daemon-reload
systemctl restart docker

 JDK installation

Install JDK11

If it is a tar.gz file, execute the decompression command

tar -zxvf jdk-11.0.11_linux-x64_bin.tar.gz

After decompression, it is installed in the current directory by default

Set java environment variables in /etc/profile file

Enter the command to check if the installation is complete

java -version

 The above prompt appears, indicating that the jdk installation is normal

redis installation

Run redis with docker

docker run -d --name redis -p 6390:6379 redis --requirepass "123456"

After the installation is complete, check the redis process, as shown in the figure above, the installation is normal

nacos console installation 

Download the nacos compressed package and use the following command to decompress it

tar -zxvf nacos-server-1.2.0.tar.gz

Enter the bin directory under the nacos installation path to execute the startup command

./startup.sh -m standalone

 Use the ps command to view the process status

 Enter http://your ip:8848 to start the nacos console

sentinel console installation 

Download the sentinel-dashboard-1.8.2.jar package, open the command line window in the directory where the jar package is located, and execute the following command to start the console

java -jar sentinel-dashboard-1.8.2.jar

 Enter the default username and password sentinel to enter the main interface

rocketmq environment construction 

Environmental requirements

JDK 11.0.5

4G+ free

You can use the wget command to download, decompress and install

wget
https://archive.apache.org/dist/rocketmq/4.5.1/

fastdfs installation

1. Download the fastdfs image

docker pull registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs

2. Start mirroring

docker run -d --restart=always --
privileged=true --net=host --name=fastdfs -e
IP=192.168.139.128 -e WEB_PORT=8888 -v
${HOME}/fastdfs:/var/local/fdfs registry.cn-beijing.aliyuncs.com/tianzuo/fastdfs

3. View the mirror image

docker ps -a

5. Test upload

vim /etc/fdfs/client.conf
#需要修改的内容如下
base_path=/home/fastdfs
#tracker服务器IP和端口
tracker_server=192.168.139.128:22122
#保存后测试,返回ID表示成功 如：group1/M00/00/00/xxx.png
/usr/bin/fdfs_upload_file /etc/fdfs/client.conf /root/fastdfs/1.png

mysql installation

Download the necessary installation files, execute the installation commands in order, initialize mysql after completion, and modify the initial password

Download the necessary installation files, execute the installation commands in order, initialize mysql after completion, and modify the initial password

Remove mariadb first , and then install and decompress mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar. After decompression, a series of rpm installation packages will be generated. The order of installation is 1) mysql-community-common- 5.7.28-1.el7.x86_64.rpm 2) mysql-community-libs-5.7.28-1.el7.x86_64.rpm 3) mysql-community-libs-compat-5.7.28-1.el7.x86_64. rpm 4) mysql-community-client-5.7.28-1.el7.x86_64.rpm 5) mysql-community-server-5.7.28-1.el7.x86_64.rpm 6) mysql-community-devel-5.7.28 -1.el7.x86_64.rpm 

initialize mysql 

mysqld --initialize --user=mysql

View initial password

cat /var/log/mysqld.log

Enter mysql and change the initial password

>mysql -uroot -p
>set password=password('123456');

mycat install

Download Mycat-server-1.6.7.5-release-linux.tar.gz, unzip it, enter the mycat/bin directory, and execute the startup command

./mycat start 启动
./mycat stop 停止
./mycat restart 重启
./mycat status 查看状态

Access mycat, after the connection is successful, it is the same as operating mysql

mysql -uroot -proot -h127.0.0.1 -P8066

mysql master-slave build

I'll talk about it later

Read-write separation configuration

I'll talk about it later

idea installation

Download and install by yourself, the 2020.2 version is used in the project
