Linux安装Nacos

一、先来选择SpringCloudAlibaba的版本吗，最终确认了2.2.6的版本对应Nacos版本为1.4.2

二、下载Nacos1.4.2

nacos1.4.2的下载路径：Release 1.4.2 (Apr 29th, 2021) · alibaba/nacos · GitHub

三、上传至服务器（工具：FileZilla），我放的路径为/opt/nacos

四、解压（工具：Xshell）

tar -zxvf nacos-server-1.4.2.tar.gz

五、进入解压后的nacos文件目录下，进入到bin目录下

cd /opt/nacos/nacos/bin

六、编辑 vim startup.sh脚本，修改

1、查看java位置

[root@master ~]# which java/usr/local/jdk-11/bin/java

2、修改启动脚本（startup.sh）

vim startup.sh

七、进入/opt/nacos/nacos/conf目录下

cd /opt/nacos/nacos/conf

八、执行nacos自带的sql文件

创建数据库，数据库脚本在源码包有，在 nacos/conf/nacos-mysql.sql，把这个导入到数据库中

九、编辑 application.properties 修改如下

vim application.properties

十、单机启动，进入 /opt/nacos/nacos/bin 执行./startup.sh -m standalone

[root@master bin]# ./startup.sh -m standalone/usr/local/jdk-11/bin/java  -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/opt/nacos/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=102400 -Dloader.path=/opt/nacos/nacos/plugins/health,/opt/nacos/nacos/plugins/cmdb -Dnacos.home=/opt/nacos/nacos -jar /opt/nacos/nacos/target/nacos-server.jar  --spring.config.additional-location=file:/opt/nacos/nacos/conf/ --logging.config=/opt/nacos/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288nacos is starting with standalonenacos is starting，you can check the /opt/nacos/nacos/logs/start.out

十一、查看日志(cat /opt/nacos/nacos/logs/start.out)

可以看见下面的日志中，内网地址：http://192.168.106.141:8848/nacos/index.html

[root@master bin]# cat /opt/nacos/nacos/logs/start.out/usr/local/jdk-11/bin/java  -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/opt/nacos/nacos/logs/nacos_gc.log:time,tags:filecount=10,filesize=102400 -Dloader.path=/opt/nacos/nacos/plugins/health,/opt/nacos/nacos/plugins/cmdb -Dnacos.home=/opt/nacos/nacos -jar /opt/nacos/nacos/target/nacos-server.jar  --spring.config.additional-location=file:/opt/nacos/nacos/conf/ --logging.config=/opt/nacos/nacos/conf/nacos-logback.xml --server.max-http-header-size=524288         ,--.       ,--.'|   ,--,:  : |                                           Nacos 1.4.2,`--.'`|  ' :                       ,---.

十一、默认用户和密码一样：nacos（没关防火墙去关防火墙）

单机部署完成

题外话：设置开机自启动

一、进入/lib/systemd/system目录, 创建nacos.service文件

cd /lib/systemd/systemtouch nacos.service

二、编辑nacos.service文件, 增加如下信息 (nacos路径替换成自己的路径即可)

[Unit]Description=nacosAfter=network.target[Service]Type=forkingExecStart=/usr/nacos-server-1.1.3/nacos/bin/startup.sh -m standaloneExecReload=/usr/nacos-server-1.1.3/nacos/bin/shutdown.shExecStop=/usr/nacos-server-1.1.3/nacos/bin/shutdown.shPrivateTmp=true[Install]WantedBy=multi-user.target

三、编辑nacos/bin目录下的startup.sh, 增加JAVA_HOME

四、执行以下命令

重新加载所有service服务：systemctl daemon-reload

开机启动nacos.service：systemctl enable nacos.service

查看该service是否开机启用：systemctl is-enabled nacos.service

启动该服务：systemctl start nacos.service

查看该服务状态：systemctl status nacos.service

完整的代码展示

[root@master bin]# vim startup.sh[root@master bin]# systemctl daemon-reload[root@master bin]# systemctl enable nacos.service[root@master bin]# systemctl is-enabled nacos.serviceenabled[root@master bin]# systemctl start nacos.service[root@master bin]# systemctl status nacos.service● nacos.service - nacos   Loaded: loaded (/usr/lib/systemd/system/nacos.service; enabled; vendor preset: disabled)   Active: active (running) since 四 2022-09-15 09:42:39 CST; 5s ago  Process: 1577 ExecStart=/opt/nacos/nacos/bin/startup.sh -m standalone (code=exited, status=0/SUCCESS)   CGroup: /system.slice/nacos.service           └─1601 /usr/local/jdk-11/bin/java -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:gc*:file=/opt/nacos/nacos/...9月 15 09:42:39 master systemd[1]: Starting nacos...9月 15 09:42:39 master startup.sh[1577]: /usr/local/jdk-11/bin/java  -Xms512m -Xmx512m -Xmn256m -Dnacos.standalone=true -Dnacos.member.list= -Xlog:g...9月 15 09:42:39 master startup.sh[1577]: nacos is starting with standalone9月 15 09:42:39 master startup.sh[1577]: nacos is starting，you can check the /opt/nacos/nacos/logs/start.out9月 15 09:42:39 master systemd[1]: Started nacos.Hint: Some lines were ellipsized, use -l to show in full.
