sh file in Linux manages the startup and shutdown of a single-machine Nacos cluster

Note:
The premise is that jdk is installed in the system and the environment variables have been configured.
Environment: CentOS8.5 stand-alone pseudo-cluster
nacos version: 2.2.0

1. Create a nacos_cluster.sh. The following is all the text. Just copy and paste it.

#!/bin/bash
# 不要忘了改成自己的集群地址
NACOS_DIR_1="/usr/local/nacoscluster/nacos8848/bin"
NACOS_DIR_2="/usr/local/nacoscluster/nacos8850/bin"
NACOS_DIR_3="/usr/local/nacoscluster/nacos8852/bin"

start_instances() {
    
    
    start_instance $NACOS_DIR_1
    start_instance $NACOS_DIR_2
    start_instance $NACOS_DIR_3
}

start_instance() {
    
    
    local nacos_dir=$1
    cd $nacos_dir
    ./startup.sh > /dev/null 2>&1 &
    echo "Nacos instance at $nacos_dir started."
}

stop_instances() {
    
    
    stop_instance $NACOS_DIR_1
    stop_instance $NACOS_DIR_2
    stop_instance $NACOS_DIR_3
}

stop_instance() {
    
    
    local nacos_dir=$1
    cd $nacos_dir
    ./shutdown.sh 
        echo "Nacos instance at $nacos_dir stop success."
}

case "$1" in
    start)
        start_instances
        ;;
    stop)
        stop_instances
        ;;
    restart)
        stop_instances
        sleep 3
        start_instances
        ;;
    *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
        ;;
esac

2. In the terminal, use the following command to grant execution permissions to the sh file:

 chmod +x  nacos_cluster.sh

3. Now, you can run

./nacos_cluster.sh start 启动集群
./nacos_cluster.sh stop 停止集群
./nacos_cluster.sh restart  重启集群
