redis 5.0.3主从 部署

环境准备

• 准备机器

节点名称	ip地址	cpu	内存
yz-redis-prod10067	10.148.100.67	8c	32G
yz-redis-prod10068	10.148.100.68	8c	32G

• 系统配置

#修改系统参数
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag

#加入开机启动项
vi /etc/rc.local
echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag
echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled

#修改内核参数
vi /etc/sysctl.conf

vm.overcommit_memory = 1
net.core.somaxconn= 1024
vm.max_map_count=655360

#使内核参数生效
sysctl -p

#修改连接数
ulimit -n 655350

• 下载安装包编辑

wget http://download.redis.io/releases/redis-5.0.3.tar.gz
tar -xf redis-5.0.3.tar.gz -C /opt
cd /opt/redis-5.0.3
make && make install

• 主节点修改配置文件并启动

mkdir /export/redis6600
cd /export/redis6600
mkdir  {data,etc,logs}

测试主从

#在主节点添加key
redis-cli  -p 6600
127.0.0.1:6600> AUTH Mso7-Bk0=wV~O
OK
127.0.0.1:6600> SET testa aaa
OK
127.0.0.1:6600> get testa
"aaa"

#从节点验证
# redis-cli  -p 6600
127.0.0.1:6600>  AUTH Mso7-Bk0=wV~O
OK
127.0.0.1:6600> get testa
"aaa"

#证明主从配置成功。
