tar zxvf redis-2.8.13.tar.gz
cd redis-2.8.13
make
1、安装主库
mkdir /opt/redis/sbin -p
mkdir /opt/redis/bin -p
mkdir /data/redis/redis6379/
cp redis.conf /data/redis/redis6379/6379.conf【配置文件下拉到最底部】
cd src
cp redis-se* /opt/redis/sbin/
cp redis-check-dump /opt/redis/bin/
cp redis-check-aof /opt/redis/bin/
cp redis-cli /opt/redis/bin/
启动:
/opt/redis/sbin/redis-server /data/redis/redis6379/6379.conf
关闭：
/opt/redis/bin/redis-cli shutdown
系统初始化：
sed -i -r '/vm.overcommit_memory*/d' /etc/sysctl.conf
sed -i -r '/vm.swappiness*/d' /etc/sysctl.conf
echo "vm.overcommit_memory = 1" >>/etc/sysctl.conf
echo "vm.swappiness = 1" >>/etc/sysctl.conf
/sbin/sysctl -q -p /etc/sysctl.conf
sed -i -r '/redis soft nofile.*/d' /etc/security/limits.conf
sed -i -r '/redis hard nofile.*/d' /etc/security/limits.conf
echo "redis soft nofile 288000" >> /etc/security/limits.conf
echo "redis hard nofile 288000" >> /etc/security/limits.conf
sed -i -r '/redis soft nproc.*/d' /etc/security/limits.conf
sed -i -r '/redis hard nproc.*/d' /etc/security/limits.conf
echo "redis soft nproc unlimited">>/etc/security/limits.conf
echo "redis hard nproc unlimited">>/etc/security/limits.conf
2、安装从库
mkdir -p /data/redis/redis6380/
cd /data/redis/redis6380/
cp ../redis6379/6379.conf 6380.conf
sed -i 's/6379/6380/g' 6380.conf #使用替换配置文件中的6379为6380
echo "slaveof 192.168.98.199 6379" >> 6380.conf #在6380.conf中添加slaveof ip port
3、启动主从
先启主库：
/opt/redis/sbin/redis-server /data/redis/redis6379/6379.conf
启动从库：
/opt/redis/sbin/redis-server /data/redis/redis6380/6380.conf
4、从库日志

127.0.0.1:6379> set fuzhi 'fuzhiceshi'
OK
127.0.0.1:6379> get fuzhi
"fuzhiceshi"
