一、redis基础管理 1、安装 [root@vh01 lnmp_soft]# tar xzf redis-3.0.6.tar.gz [root@vh01 lnmp_soft]# cd redis-3.0.6/ [root@vh01 redis-3.0.6]# make && make install 2、初始化 [root@vh01 redis-3.0.6]# ./utils/install_server.sh 提示的问题全部回车，但是要观察各种文件存放的路径 3、服务管理 [root@vh01 ~]# service redis_6379 status 查看状态 [root@vh01 ~]# service redis_6379 stop [root@vh01 ~]# service redis_6379 start 4、服务器基础测试 [root@vh01 ~]# redis-cli 127.0.0.1:6379> ping PONG 127.0.0.1:6379> set username songtao OK 127.0.0.1:6379> get username "songtao" 127.0.0.1:6379> set counter 10 OK 127.0.0.1:6379> INCR counter (integer) 11 127.0.0.1:6379> GET counter "11" 5、操作字符串 127.0.0.1:6379> set first 'hello world' OK 127.0.0.1:6379> get first "hello world" 127.0.0.1:6379> SETRANGE first 6 'tedu.cn' (integer) 13 127.0.0.1:6379> get first "hello tedu.cn" 127.0.0.1:6379> APPEND username "sudan" 向变量中追加 127.0.0.1:6379> SETBIT mytest 0 1 (integer) 0 127.0.0.1:6379> SETBIT mytest 1 0 (integer) 0 127.0.0.1:6379> get mytest 127.0.0.1:6379> SETBIT peter 100 1 设置2进制的第100位为1 (integer) 0 127.0.0.1:6379> SETBIT peter 105 1 设置2进制的第105位为1 (integer) 0 127.0.0.1:6379> BITCOUNT peter 统计peter设置为1的位数有多少 (integer) 2 127.0.0.1:6379> set num1 100 相当于是num1=100 OK 127.0.0.1:6379> get num1 "100" 127.0.0.1:6379> INCR num1 相当于是num1++ (integer) 101 127.0.0.1:6379> DECR num1 相当于是num1-- (integer) 100 127.0.0.1:6379> DECRBY num1 10 # num1=num1-10 127.0.0.1:6379> INCRBY num1 10 # num1=num1+10

配置redis主从 1、主服务器使用现有的redis 2、从服务器 [root@vh02 lnmp_soft]# yum install -y gcc gcc-c++ [root@vh02 lnmp_soft]# tar xzf redis-3.0.6.tar.gz [root@vh02 lnmp_soft]# cd redis-3.0.6/ [root@vh02 redis-3.0.6]# make && make install [root@vh02 redis-3.0.6]# ./utils/install_server.sh 3、主服务器设置同步密码 [root@vh01 ~]# vim /etc/redis/6379.conf requirepass redis123 [root@vh01 ~]# service redis_6379 restart 或 [root@vh01 ~]# /etc/init.d/redis_6379 restart 4、设置关闭服务的认证密码 [root@vh01 ~]# vim /etc/init.d/redis_6379 $CLIEXEC -a redis123 -p $REDISPORT shutdown [root@vh01 ~]# service redis_6379 restart 5、配置从属服务器 [root@vh02 ~]# vim /etc/redis/6379.conf slaveof 192.168.4.1 6379 masterauth redis123 [root@vh02 ~]# service redis_6379 restart 6、验证 [root@vh02 ~]# redis-cli [root@vh01 ~]# redis-cli -h 192.168.4.1 -a redis123 192.168.4.1:6379> set aaa 100 [root@vh02 ~]# redis-cli 127.0.0.1:6379> keys * 127.0.0.1:6379> get aaa
