02、Redis 主从配置

安装参考：https://blog.youkuaiyun.com/EVISWANG/article/details/94553100

1、编辑配置文件：

   主库：/opt/redis/config/redis-6379.conf

      daemonize yes

      pidfile  /var/run/redis-6379.pid

      port 6379

      logfile "6379.log"

      dbfilename dump-6379.rdb

      dir  /opt/redis/data

      slave-read-only yes

      #save 900 1   

      #save 300 10  

      #save 60 10000

   备库：/opt/redis/config/redis-6380.conf

      daemonize yes

      pidfile  /var/run/redis-6380.pid

      port 6380

      logfile "6380.log"

      dbfilename dump-6380.rdb

      dir  /opt/redis/data

      slaveof  127.0.0.1 6379

      slave-read-only yes

      #save 900 1   

      #save 300 10  

      #save 60 10000

 

2、启动主从数据库：

   主库：

      [root@centos03ms config]# redis-server redis-6379.conf

      [root@centos03ms config]#

      [root@centos03ms config]#

      [root@centos03ms config]# ps -ef |grep redis

      root     18922     1  0 23:42 ?        00:00:00 redis-server *:6379         

      root     18934 16693  0 23:42 pts/7    00:00:00 grep redis

      [root@centos03ms config]#

      [root@centos03ms config]# redis-cli

      127.0.0.1:6379> set hello word

      OK

      127.0.0.1:6379> get hello

      "word"

      127.0.0.1:6379> info replication

      # Replication

      role:master

      connected_slaves:0

      master_repl_offset:0

      repl_backlog_active:0

      repl_backlog_size:1048576

      repl_backlog_first_byte_offset:0

      repl_backlog_histlen:0

      127.0.0.1:6379>

    备库：

      [root@centos03ms config]# redis-server redis-6380.conf

      [root@centos03ms config]# ps -ef |grep redis

      root     18922     1  0 23:42 ?        00:00:00 redis-server *:6379         

      root     19035     1  0 23:45 ?        00:00:00 redis-server *:6380         

      root     19040 16693  0 23:45 pts/7    00:00:00 grep redis

      [root@centos03ms config]# redis-cli -p 6380 info replication

      # Replication

      role:slave

      master_host:127.0.0.1

      master_port:6379

      master_link_status:up

      master_last_io_seconds_ago:2

      master_sync_in_progress:0

      slave_repl_offset:71

      slave_priority:100

      slave_read_only:1

      connected_slaves:0

      master_repl_offset:0

      repl_backlog_active:0

      repl_backlog_size:1048576

      repl_backlog_first_byte_offset:0

      repl_backlog_histlen:0

      [root@centos03ms config]#  

 

3、主从复制演示

      127.0.0.1:6379> get hello

      (nil)

      127.0.0.1:6379>

      127.0.0.1:6379> set hello word

      OK

      127.0.0.1:6379> get hello

      "word"

      127.0.0.1:6379>

    从库查询：

      127.0.0.1:6380> get hello

      "word"

      127.0.0.1:6380>
