RedisDB双机主从同步性能测试

安装redisDB

主节点

apt install redis-server

修改配置 /etc/redis/redis.conf

bind 0.0.0.0

save ""   # 禁止RDB持久化
#save 900 1
#save 300 10
#save 60 10000

appendonly no  # 禁止AOF持久化

重启服务

systemctl restart redis-server

从节点配置文件

bind 0.0.0.0

save ""   # 禁止RDB持久化
#save 900 1
#save 300 10
#save 60 10000

appendonly no  # 禁止AOF持久化

# 从节点关键配置
slaveof 172.40.20.132 6379

主从验证

主从状态

主节点执行 redis-cli info replication

root@r750-132:~# redis-cli  info replication
# Replication
role:master
connected_slaves:1
slave0:ip=172.40.20.131,port=6379,state=online,offset=84,lag=0

repl_backlog_active:1
repl_backlog_size:1048576

从节点检查

redis-cli info replication

数据同步

主节点插入数据

root@r750-132:~# redis-cli set name1 ckun
OK
root@r750-132:~# redis-cli get name1
"ckun"

从节点读取数据

root@r750-131:~# redis-cli get name1
"ckun"

测试程序

安装hiredis API

git clone https://github.com/redis/hiredis.git
cd hiredis/
make
make install
ldconfig
