Redis Standalone slave节点镜像制作

• 安装 agent
  下载青云提供的 app agent Linux 版本, Windows 版本，解压后运行 ./install.sh (Windows 下双击 install.bat)。

• 创建 /etc/confd/conf.d/redis.conf.toml

    [template]
    src = "redis.conf.tmpl"
    dest = "/opt/redis/redis.conf"
    keys = [
        "/",
    ]
    reload_cmd = "/opt/redis/bin/restart-redis-server.sh"
  

• 创建 /etc/confd/templates/redis.conf.tmpl

    {% raw %}
    aof-rewrite-incremental-fsync yes
    appendfilename appendonly.aof
    auto-aof-rewrite-percentage 10
    auto-aof-rewrite-min-size 64mb
    bind 0.0.0.0
    client-output-buffer-limit normal 0 0 0
    client-output-buffer-limit pubsub 32mb 8mb 60
    client-output-buffer-limit slave 256mb 64mb 60
    daemonize yes
    databases 16
    dbfilename dump.rdb
    dir /data/redis
    hll-sparse-max-bytes 3000
    hz 10
    logfile /data/redis/logs/redis-server.log
    loglevel notice
    lua-time-limit 5000
    pidfile /var/run/redis/redis-server.pid
    repl-disable-tcp-nodelay no  
    rdbchecksum yes
    rdbcompression yes
    save ""
    slave-priority 0
    slave-read-only yes
    slave-serve-stale-data yes
    slowlog-max-len 128
    stop-writes-on-bgsave-error yes
    tcp-backlog 511
    {{range gets "/env/*"}}{{$v := .Value}}{{ if gt ( len ( $v ) ) 0 }}{{base .Key}} {{.Value}}
    {{ else }}{{base .Key}} ""
    {{end}}{{end}}
    {{range $dir := lsdir "/hosts/master"}}{{$ip := printf "/hosts/master/%s/ip" $dir}}
    slaveof {{getv $ip}} {{getv "/env/port"}}{{end}}
    {% endraw %}
  

最后一个 range 部分是获取本节点所在集群的主节点信息，包括 IP 和端口号。

• 补充脚本
  在此例中有两个脚本 stop-redis-server.sh 和 restart-redis-server.sh，redis 官方并没有提供这些脚本，参见 主节点镜像制作指南
