nacos集羣安裝部署

1、下載nacos包

[root@manage-host updates]# wget https://github.com/alibaba/nacos/releases/download/1.2.1/nacos-server-1.2.1.tar.gz

2、解壓並修改單機的配置文件（以下所有的配置在三臺機器上都操作）

[root@manage-host updates]# tar -xf nacos-server-1.2.1.tar.gz ../
[root@manage-host updates]# cd ../nacos/conf
[root@manage-host conf]# vim application.properties
#*************** Spring Boot Related Configurations ***************#
### Default web context path:
server.servlet.contextPath=/nacos
### Default web server port:
server.port=8848


#*************** Config Module Related Configurations ***************#
### If user MySQL as datasource:
spring.datasource.platform=mysql

### Count of DB:
db.num=1

### Connect URL of DB:
db.url.0=jdbc:mysql://192.168.0.117:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=nacos
db.password=901Bcpct

3、編輯集羣配置文件

[root@manage-host conf]# cp cluster.conf.example cluster.conf
[root@manage-host conf]# vim cluster.conf
#it is ip
#example
192.168.0.117:8848
192.168.0.194:8848
192.168.0.156:8848

4、配置啓動方式

集羣啓動方式如下

[root@manage-host conf]# vim /usr/lib/systemd/system/nacos.service
[Unit]
Description=Nacos
After=network.target

[Service]
Type=simple
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nacos
User=root
WorkingDirectory=/home/deploy/nacos/
ExecStart=/home/deploy/nacos/bin/startup.sh
KillMode=process
TimeoutStopSec=60
Restart=on-failure
RestartSec=5
RemainAfterExit=no

[Install]
WantedBy=multi-user.target

單機啓動方式如下

[root@manage-host conf]# vim /usr/lib/systemd/system/nacos.service
[Unit]
Description=Nacos
After=network.target

[Service]
Type=simple
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nacos
User=root
WorkingDirectory=/home/deploy/nacos/
ExecStart=/home/deploy/nacos/bin/startup.sh -m standalone
KillMode=process
TimeoutStopSec=60
Restart=on-failure
RestartSec=5
RemainAfterExit=no

[Install]
WantedBy=multi-user.target

刷新系統配置

systemctl daemon-reload

5、設置開機啓動和啓動服務

[root@data-node1 conf]# systemctl enable nacos
[root@data-node1 conf]# systemctl start nacos

6、查詢日誌，出現successfully則證明啓動成功

7、一臺一臺驗證

http://192.168.0.194:8848/nacos/index.html

 8、配置nginx反向代理

配置文件內容如下

upstream gridcloudcluster {
    server 192.168.0.117:8848 weight=1;
    server 192.168.0.194:8848 weight=1;
    server 192.168.0.156:8848 weight=1;
}


server {
        listen       8849;
        charset UTF-8;
        server_name 192.168.0.117;
      
      location / { 
        proxy_pass http://gridcloudcluster;
        proxy_set_header   Host    $host; 
        proxy_set_header   Remote_Addr    $remote_addr;
        proxy_set_header   X-Real-IP    $remote_addr;
        proxy_set_header   X-Forwarded-For    $proxy_add_x_forwarded_for;
        index index;
        
        }
     
}

驗證nginx配置是否有誤，並重啓 

[root@manage-host nacos]# /home/deploy/nginx/sbin/nginx -t
nginx: the configuration file /home/deploy/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /home/deploy/nginx/conf/nginx.conf test is successful
[root@manage-host nacos]# /home/deploy/nginx/sbin/nginx -s reload

 9、在瀏覽器上通過nginx訪問，並登陸（默認賬號密碼都是nacos）
