Redis 安装环境
CentOS 7 master:172.31.23.28:6666 slave:172.31.23.28:6666
Redis 下载
下载地址:http://download.redis.io/releases/redis-4.0.9.tar.gz
编译安装主从都需要:
$ wget http://download.redis.io/releases/redis-4.0.9.tar.gz
$ tar xvzf redis-4.0.9.tar.gz -C /usr/local/
$ cd /usr/local/redis-4.0.9
$ make & make test
编译过程报错如下:
(1)
zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory #include <jemalloc/jemalloc.h> ^ compilation terminated. make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory `/usr/local/redis-4.0.9/src' make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory `/usr/local/redis-4.0.9/src' make: *** [all] Error 2 make: *** [test] Error 2 [1]+ Exit 2 make
解决方法:
make MALLOC=libc
(2)
[root@ip-172-31-18-226 redis-4.0.9]# make test cd src && make test make[1]: Entering directory `/usr/local/redis-4.0.9/src' CC Makefile.dep make[1]: Leaving directory `/usr/local/redis-4.0.9/src' make[1]: Entering directory `/usr/local/redis-4.0.9/src' You need tcl 8.5 or newer in order to run the Redis test make[1]: *** [test] Error 1 make[1]: Leaving directory `/usr/local/redis-4.0.9/src' make: *** [test] Error 2
解决方法:
yum install -y tcl
主redis配置

启动观察
[root@ip-172-31-23-28 redis6666]# /usr/local/redis-4.0.9/src/redis-server /data/redis6666/redis6666.conf [root@ip-172-31-23-28 redis6666]# ps -axf|grep redis 22166 pts/0 S+ 0:00 \_ grep --color=auto redis 22161 ? Ssl 0:00 /usr/local/redis-4.0.9/src/redis-server *:6666
从redis配置
从配置比较简单,如下:
daemonize yes

unixsocketperm 755
timeout 30
loglevel notice

注,就增加了一行,然后我们将从库启动起来,看看状态

好了,看状态就成了,下来我们再测试一下,
主库:
127.0.0.1:6666> set name zhangsan OK
从库:
127.0.0.1:6666> get name "zhangsan"
好了,到此为止
