1.nacos的下载（注意nacos需要和springcloud alibaba 版本对应）
代码语言：javascript复制下载合适版本之后，把nacos的3个配置文件分别修改配置文件1. cluster.conf
格式为：IP 端口号
172.168.139.101:8848
192.168.187.161:8848
192.168.140.196:8848
注意：发布在云服务上时其他几个为外网IP地址 端口号,本机为内网的IP地址配置文件2: application.properties
该配置文件需要配置持久化（mysql配置）
#################
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos
db.user.0=root

(1)修改启动命令
while getopts ":m:f:s:c:p:d:" opt
d) #在该位置配置上端口号的配置命令
PROT=$OPTARG;; #加入该代码
(2)修改占用内存
## 在该位置限制nacos启动之后占用的内存 -Xms600m -Xmx912m 最小600M 最多912M
JAVA_OPT="${JAVA_OPT} -server -Xms600m -Xmx912m -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
(3)在最下面
## 新增如下配置： -Dserver.prot=${PROT}
nohup $JAVA -Dserver.prot=${PROT} ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 &
