7. 查看本地源

准备配置文件

这个demo使用本地单节点进行演示，所以选择了官方提供的mini-local-example.yaml配置文件。
获取方式：https://github.com/oceanbase/obdeploy/blob/master/example/mini-local-example.yaml
内容如下：

oceanbase-ce:
  servers:
    # Please don't use hostname, only IP can be supported
    - 127.0.0.1
  global:
    #  The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
    home_path: /root/observer	
    # The directory for data storage. The default value is $home_path/store.
    # data_dir: /data
    # The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
    # redo_dir: /redo
    # Please set devname as the network adaptor's name whose ip is  in the setting of severs.
    # if set severs as "127.0.0.1", please set devname as "lo"
    # if current ip is 192.168.1.10, and the ip's network adaptor's name is "eth0", please use "eth0"
    devname: lo
    mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
    rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
    zone: zone1
    cluster_id: 1
    # please set memory limit to a suitable value which is matching resource.
    memory_limit: 8G # The maximum running memory for an observer
    system_memory: 4G # The reserved system memory. system_memory is reserved for general tenants. The default value is 30G.
    stack_size: 512K
    cpu_count: 16
    cache_wash_threshold: 1G
    __min_full_resource_pool_memory: 268435456
    workers_per_cpu_quota: 10
    schema_history_expire_time: 1d
    # The value of net_thread_count had better be same as cpu's core number.
    net_thread_count: 4
    sys_bkgd_migration_retry_num: 3
    minor_freeze_times: 10
    enable_separate_sys_clog: 0
    enable_merge_by_turn: FALSE
    datafile_disk_percentage: 20 # The percentage of the data_dir space to the total disk space. This value takes effect only when datafile_size is 0. The default value is 90.
    syslog_level: INFO # System log level. The default value is INFO.
    enable_syslog_wf: false # Print system logs whose levels are higher than WARNING to a separate log file. The default value is true.
    enable_syslog_recycle: true # Enable auto system log recycling or not. The default value is false.
    max_syslog_file_count: 4 # The maximum number of reserved log files before enabling auto recycling. The default value is 0.
    # root_password: # root user password, can be empty

注意事项：

1. servers：只能使用ip，不能使用主机名（hostname）。
2. cpu_count:CPU数量可以大于物理CPU的数量。
