CenotOS环境Nacos安装，设置开机自启动 CenotOS环境Nacos安装，设置开机自启动1、下载nacos下载地址：https://github.com/alibaba/nacos/releases2、安装进入nacos所在目录，执行如下命令tar -zxvf nacos-server-2.0.3.tar.gz -C /usr/local/3、单机启动修改/usr/local/nacos/bin目录下startup.sh启动文件设置单机启动，修改export MODE="cluster"值为standaloneexport MODE="standalone"4、启动测试进入/usr/local/nacos/bin目录下，执行启动命令./startup.sh启动失败，查看/usr/local/nacos/logs下start.out日志文件，报错如下：/usr/local/java/jdk-11.0.10/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/usr/local/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=102400 -Dloader.path=/usr/local/nacos/plugins/health,/usr/local/nacos/plugins/cmdb -Dnacos.home=/usr/local/nacos -jar /usr/local/nacos/target/nacos-server.jar --spring.config.additional-location=file:/usr/local/nacos/conf/ --logging.config=/usr/local/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288 Error: Could not find or load main class Caused by: java.lang.ClassNotFoundException: 5、解决方案进入/usr/local/nacos/bin/目录，修改启动文件startup.sh，修改内容如下：x JAVA_OPT_EXT_FIX="-Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext" √ JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext" x echo "$JAVA $JAVA_OPT_EXT_FIX ${JAVA_OPT}" √ echo "$JAVA ${JAVA_OPT}" x echo "$JAVA $JAVA_OPT_EXT_FIX ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out 2>&1 & x nohup "$JAVA" "$JAVA_OPT_EXT_FIX" ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 & √ echo "$JAVA ${JAVA_OPT}" > ${BASE_DIR}/logs/start.out 2>&1 & √ nohup $JAVA ${JAVA_OPT} nacos.nacos >> ${BASE_DIR}/logs/start.out 2>&1 &x：表示需要替换的，√：表示修改后的。6、再次测试进入/usr/local/nacos/bin目录下，执行启动命令./startup.sh输出结果：/usr/local/java/jdk-11.0.10/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/usr/local/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=102400 -Dloader.path=/usr/local/nacos/plugins/health,/usr/local/nacos/plugins/cmdb -Dnacos.home=/usr/local/nacos -jar /usr/local/nacos/target/nacos-server.jar --spring.config.additional-location=file:/usr/local/nacos/conf/ --logging.config=/usr/local/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288 nacos is starting with standalone nacos is starting，you can check the /usr/local/nacos/logs/start.out表示之前启动问题解决，启动成功。7、访问nacos打开浏览器输入CentOS地址+端口+项目访问，即可看到nacos登录页面。http://192.168.56.10:8848/nacos8、随机启动配置8.1、进入 /lib/systemd/system目录cd /lib/systemd/system8.2、在该目录下，创建文件nacos启动文件vi nacos.service添加内容如下[Unit] Description=nacos After=network.target [Service] Environment="JAVA_HOME=/usr/local/java/jdk-11.0.10" Type=forking ExecStart=/usr/local/nacos/bin/startup.sh -m standalone ExecReload=/usr/local/nacos/bin/shutdown.sh ExecStop=/usr/local/nacos/nacos/bin/shutdown.sh PrivateTmp=true [Install] WantedBy=multi-user.target注意：修改自己nacos所在路径8.3、重载所有服务systemctl daemon-reload8.4、设置开机启动systemctl enable nacos.service8.5、查看开机启动状态systemctl is-enabled nacos.service8.6、查看服务状态systemctl status nacos8.7、手动启动 Nacossystemctl start nacos8.7、手动停止Nacossystemctl stop nacos8.8、手动重启systemctl restart nacos9、测试自启动重启CentOS系统，查看Nacos是否自自动查看Nacos服务状态systemctl status nacos输出结果：● nacos.service - nacos Loaded: loaded (/usr/lib/systemd/system/nacos.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2022-10-24 15:15:16 UTC; 1min 7s ago Process: 707 ExecStart=/usr/local/nacos/bin/startup.sh -m standalone (code=exited, status=0/SUCCESS) Tasks: 194 Memory: 547.8M CGroup: /system.slice/nacos.service └─748 /usr/local/java/jdk-11.0.10/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/usr/local/nacos/logs/nacos_gc.log:time,tag...

Hint: Some lines were ellipsized, use -l to show in full.表示已经启动成功。通过IP+端口+项目访问登录页面测试http://192.168.56.10:8848/nacos已经可以成功访问Nacos登录页面了。
