创建数据目录

mkdir -pv /data/nacos/{conf,logs}

创建配置文件

应用配置文件

cat > /data/nacos/conf/ << 'EOF'
#=false
#=false
#=false
#=/**
#=http://localhost:9200
# metrics for prometheus
#=*

# metrics for elastic search

集群配置文件

cat > /data/nacos/conf/ << 'EOF'
#it is ip 
#example 
3.1.101.33
3.1.101.34
3.1.101.35

配置Mysql数据库

创建数据库nacos_config,并授权

create database nacos_config;
grant all privileges on nacos_config.* to "nacos"@"%" identified by "nacospwd";
flush privileges;

导入数据库

mysql -unacos -pnacospwd nacos_config <

LB部署

nginx配置文件,四层转发

stream {
    log_format  main  '$remote_addr $upstream_addr - [$time_local] $status $upstream_bytes_sent';
    access_log  /var/log/nginx/  main;
    
    upstream nacos-server {
       hash $remote_addr consistent;
       server 192.168.2.150:8848;
       server 192.168.2.151:8848;
       server 192.168.2.152:8848;
    }
    
    server {
       listen 8848;
       proxy_pass nacos-server;
    }
}

注意nginx节点不要和nacos节点重合,如果重合,需要修改端口

sentinel(流量控制)

Docker镜像

docker pull bladex/sentinel-dashboard:1.8.0

创建数据目录

mkdir -pv /data/sentinel/logs

docker-compose编排

seata(分布事务)

部署参考: /zh-cn/docs/ops/

Docker镜像

docker pull seataio/seata-server:1.4.1

创建配置目录

mkdir -pv /data/seata/{config,logs}

创建配置文件

cat > /data/seata/config/ << 'EOF'
# 注册中心配置
registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"
  loadBalance = "RandomLoadBalance"
  loadBalanceVirtualNodes = 10

  nacos {
    application = "seata-server"
    serverAddr = "3.1.101.45:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
# seata-server配置中心
config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "file"
  file {
    name = "file:/root/seata-config/"
  }
}
EOF


cat > /data/seata/config/ << 'EOF'
## transaction log store, only used in seata-server

  ## store mode: file、db、redis
  mode = "db"
  
  ## database store property
  db {
    ## the implement of , such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
    datasource = "druid"
    ## mysql/oracle/postgresql/h2/oceanbase etc.
    dbType = "mysql"
    driverClassName = ""
    url = "jdbc:mysql://6.1.14.87:3306/seata"
    user = "seata"
    password = "seata"
    minConn = 5
    maxConn = 100
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }
}
EOF

以上配置为seata集群模式,seata可配置多台,使用mysql数据库,并将服务注册到nacos

如果mysql版本为8.0,需要修改驱动类名称

修改前:
driverClassName = ""
修改后:
driverClassName = ""

数据库配置

配置高可用需要在配置的数据库中添加3张表

creata database seata;
grant all privileges on seata.* to "seata"@"local" identified by "seata";
flush privileges;

导入如下表

mysql -useata -pseatapwd seata <

使用自定义配置文件时必须指定环境变量 SEATA_CONFIG_NAME, 并且值需要以file:开始, 如: file:/root/seata-config/registry,将会加载 /root/seata-config/ 作为配置文件

果需要同时指定 文件，需要将的的值改为类似file:/root/：
