配置文件

主从配置

loglevel 安装默认的设置为 verbose：

  • 1）debug：会打印出很多信息，适用于开发和测试阶段
  • 2）verbose（冗长的）：包含很多不太有用的信息，但比debug要清晰一些
  • 3）notice：适用于生产模式
  • 4）warning : 警告信息

master.conf 配置如下：

requirepass Pd4Ervty3w6NmSB2Fm.
sentinel auth-pass limsmaster PN4Hxgcm.
sentinel down-after-milliseconds limsmaster 30000
sentinel failover-timeout limsmaster 180000
sentinel parallel-syncs limsmaster 2

sentinel-2.conf 配置如下：

docker-compose 配置

创建外部网络

如果没有外部网络，需要运行以下命令创建：

1
2
3
4
5
# 查看网络列表
docker network ls

# 创建网络
docker network create --driver bridge --subnet 10.10.13.0/24 --gateway 10.10.13.1 docker_compose_net

新建 docker-compose.yml 文件。
