redis配置笔记

#cd /opt
#tar -zxvf redis-4.0.6.tar.gz
#cd redis-4.0.6
#make
#cd src
#make install PREFIX=/usr/local/redis
#mkdir –p /usr/local/redis/etc放配置文件
#mv /opt/redis-4.0.6/redis.conf /usr/local/redis/etc/
修改配置文件：
默认情况，Redis不是在后台运行，我们需要把redis放在后台运行
vi /usr/local/redis/etc/redis.conf
将daemonize的值改为yes
bind 192.168.100.101
save <seconds> <changes>：保存快照的频率
将其注释掉：
# save 900 1
# save 300 10
# save 60 10000

启动：

# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
10422:C 09 Jan 16:41:21.005 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
10422:C 09 Jan 16:41:21.005 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=10422, just started
10422:C 09 Jan 16:41:21.005 # Configuration loaded

测试：

[root@redis-master bin]# ./redis-cli -h 10.174.66.201 -p  或
[root@redis-master bin]# ./redis-cli
192.168.100.101:> info

) "key"
192.168.100.101:> FLUSHALL
OK
192.168.100.101:>

停止redis实例

# ./redis-cli -h 192.168.100.101 -p
192.168.100.101:> SHUTDOWN

redis主从配置，修改slave从服务器的配置文件。
slaveof 192.168.100.101 6379 (映射到主服务器上)

查看master服务器：

[root@redis-master bin]# ./redis-cli -h 192.168.100.101 -p
192.168.100.101:> info

查看slave服务器:

[root@redis-slave bin]# ./redis-cli -h 10.174.66.202 -p
192.168.100.102:> info

添加开机自启动：

#crontab -e

@reboot  /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
