1. Download nacos
Select the tar.gz download of the matching springcloud version
Releases · alibaba/nacos · GitHub
Unzip it after downloading. Respectively copy as nacos8849, nacos8850, nacos8851 three folders
Two, modify the configuration
Modify the configuration of the files in the three folders
1.application.properties
1. Modify
server.port=8849
The other two were changed to
server.port=8850
server.port=8851
2. Let go of annotations
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=root
db.password.0=123456
2.cluster.conf
cluster.conf.example copy a cluster.conf
changed to
10.0.4.16:8849
10.0.4.16:8850
10.0.4.16:8851
Among them, 10.0.4.16 is the local address of the server intranet
3.startup.sh
Enter the bin directory and modify startup.sh.
Modify xms, xmx, xmn in else according to the server memory size.
If the configured memory is too large, the memory will not be enough.
if [[ "${MODE}" == "standalone" ]]; then JAVA_OPT="${JAVA_OPT} -Xms512m -Xmx512m -Xmn256m" JAVA_OPT="${JAVA_OPT} -Dnacos.standalone=true" else if [[ "${EMBEDDED_STORAGE}" == "embedded" ]]; then JAVA_OPT="${JAVA_OPT} -DembeddedStorage=true" fi JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m" JAVA_OPT="${JAVA_OPT} -XX:-OmitStackTraceInFastThrow -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${BASE_DIR}/logs/java_heapdump.hprof" JAVA_OPT="${JAVA_OPT} -XX:-UseLargePages"
Three, nginx configuration
Modify nginx configuration
increase server at the same level
upstream nacoscluster {
server 127.0.0.1:8849;
server 127.0.0.1:8850;
server 127.0.0.1:8851;
}
increase in server
location /nacos/ {
proxy_pass http://nacoscluster/nacos/;
}
4. Start
After modifying the configuration, execute the startup.sh under each folder to start nacos.
Start nginx. (The nginx port configuration file is 80)
After startup, access http://ip:port/nacos/ through the external network
Among them, ip is the address of the external network, and port is the port number mapped to the external network by nginx.
After logging in, you can see the list of nodes managed by the cluster
