Nacos集群部署

架构规划

jdk版本

mysql版本

 ~# groupadd mysql
 ~# useradd -r -g mysql -s /bin/false mysql
 ~# wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
 ~# tar xf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
 ~# cd /usr/local/
 ~# ln -s mysql-5.7.29-linux-glibc2.12-x86_64/ mysql
 ~# chown -R root.root /usr/local/mysql/
 ~# echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
 ~# . /etc/profile.d/mysql.sh
 ~# cp /etc/my.cnf{,.bak}
 ~# vim /etc/my.cnf
 [mysqld]
 datadir=/data/mysql
 skip_name_resolve=1
 socket=/data/mysql/mysql.sock    
 log-error=/data/mysql/mysql.log
 pid-file=/data/mysql/mysql.pid
 [client]
 socket=/data/mysql/mysql.sock
 ​
 ~# mkdir /data/mysql
 mysqld --initialize --user=mysql --datadir=/data/mysql
 # ...省略...
 ~# grep password /data/mysql/mysql.log

 ~# mysql -uroot -p'IMXw:e_fq5Mz'
 mysql>  set password for root@localhost = password('root');

安装Nacos

所有nacos节点进行下面操作

 ~# wget https://github.com/alibaba/nacos/releases/download/2.3.1/nacos-server-2.3.1.tar.gz
 ~# tar xf nacos-server-2.3.1.tar.gz -C /usr/local/
 `修改启动脚本`
 ~# vim /usr/local/nacos/bin/startup.sh

 `nacos创建用户`
 mysql> CREATE USER 'nacos'@'%' IDENTIFIED BY 'nacos123';
 mysql> GRANT ALL PRIVILEGES ON nacos.* TO 'nacos'@'%';
 mysql> flush privileges;
 `验证用户连接`

 `启动加载数据库`
 ~# scp /usr/local/nacos/conf/mysql-schema.sql 192.168.139.35:
 [root@mysql-server ~]# mysql -uroot -p123456
 mysql> create database nacos;
 mysql> use nacos;
 mysql> source /root/mysql-schema.sql
 `或者`
 ~# mysql -unacos -pnacos123 -h192.168.139.35 nacos < /usr/local/nacos/conf/mysql-schema.sql

• 修改nacos配置文件

 `修改application.properties文件`
 ~# vim /usr/local/nacos/conf/application.properties

 `修改集群配置文件`
 ~# cp /usr/local/nacos/conf/cluster.conf.example /usr/local/nacos/conf/cluster.conf
 ~# vim /usr/local/nacos/conf/cluster.conf
 192.168.139.32:8848
 192.168.139.33:8848
 192.168.139.34:8848
 `将配置文件传输到其他节点`
 ~# scp -r /usr/local/nacos/ 192.168.139.33:/usr/local/
 ~# scp -r /usr/local/nacos/ 192.168.139.34:/usr/local/

启动nacos

 ~# cd /usr/local/nacos/bin/ && bash startup.sh ;tail -f /usr/local/nacos/logs/start.out
