Linux安装Nacos
一、先来选择SpringCloudAlibaba的版本，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/java2、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=524288
nacos is starting with standalone
nacos 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

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/system
touch 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=nacos
After=network.target
[Service]
Type=forking
ExecStart=/usr/nacos-server-1.1.3/nacos/bin/startup.sh -m standalone
ExecReload=/usr/nacos-server-1.1.3/nacos/bin/shutdown.sh
ExecStop=/usr/nacos-server-1.1.3/nacos/bin/shutdown.sh
PrivateTmp=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.service
enabled
[root@master bin]# systemctl start nacos.service
[root@master bin]# systemctl status nacos.service
