2. Linux下安装redis以及简单管理

安装Redis

1. 下载redis安装包

http://download.redis.io/releases/redis-3.2.8.tar.gz

1. 将压缩包拷贝到/opt目录下并且解压缩

[root@hm707 redis-3.2.8]# tar -zxvf redis-3.2.8.tar.gz

1. 进入到解压缩后的目录中，执行make命令

注意：执行make时需要有gcc环境，如果没有需要提前安装

[root@hm707 redis-3.2.8]# yum install gcc-c++ -y

再次执行make时还是会报错，错误如下

[root@hm707 redis-3.2.8]# makecd src && make allmake[1]: Entering directory `/opt/redis-3.2.8/src'    CC adlist.oIn file included from adlist.c:34:zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directoryzmalloc.h:55:2: error: #error "Newer version of jemalloc required"make[1]: *** [adlist.o] Error 1make[1]: Leaving directory `/opt/redis-3.2.8/src'make: *** [all] Error 2

该错误是因为之前在没有gcc环境时执行make命令后生成了一些文件目录导致的，只需要执行make distclean之后在执行make

1. 最后执行make install

[root@hm707 redis-3.2.8]# make installcd src && make installmake[1]: Entering directory `/opt/redis-3.2.8/src'Hint: It's a good idea to run 'make test' ;)    INSTALL install    INSTALL install    INSTALL install    INSTALL install    INSTALL install

简单管理

1. 目录的简单说明

安装完成后的可执行文件在/usr/local/bin目录下

[root@hm707 redis-3.2.8]# cd /usr/local/bin[root@hm707 bin]# lltotal 26348-rwxr-xr-x. 1 root root 5580327 Apr 27 23:09 redis-benchmark-rwxr-xr-x. 1 root root   22217 Apr 27 23:09 redis-check-aof-rwxr-xr-x. 1 root root 7829986 Apr 27 23:09 redis-check-rdb-rwxr-xr-x. 1 root root 5709187 Apr 27 23:09 redis-clilrwxrwxrwx. 1 root root      12 Apr 27 23:09 redis-sentinel -> redis-server-rwxr-xr-x. 1 root root 7829986 Apr 27 23:09 redis-server

修改配置文件，让redis可以后台启动

[root@hm707 bin]# pwd/opt/redis-3.2.8[root@hm707 bin]# mkdir /myredis[root@hm707 bin]# cp redis.conf /myredis/[root@hm707 bin]# vim /myredis/redis.conf

daemonize改为yes

################################# GENERAL ###################################### By default Redis does not run as a daemon. Use 'yes' if you need it.# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.daemonize yes

启动redis服务

[root@hm707 bin]# pwd/usr/local/bin[root@hm707 bin]# redis-server /myredis/redis.conf[root@hm707 bin]# ps -ef | grep redisroot      6048     1  0 23:26 ?        00:00:00 redis-server 127.0.0.1:6379     root      6054  2438  0 23:27 pts/1    00:00:00 grep redis

使用redis-cli -p 6379连接redis服务.
SHUTDOWN关闭服务

[root@hm707 bin]# pwd/usr/local/bin[root@hm707 bin]# redis-cli -p 6379127.0.0.1:6379> pingPONG127.0.0.1:6379> set k1 helloOK127.0.0.1:6379> get k1"hello"127.0.0.1:6379> SHUTDOWNnot connected> exit[root@hm707 bin]# ps -ef|grep redisroot      6075  2438  0 23:31 pts/1    00:00:00 grep redis

使用Redis-benchmark测试redis性能

下面是简单的例子，具体参考 http://www.redis.cn/topics/benchmarks.html

Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests]> [-k <boolean>]  -h <hostname>      Server hostname (default 127.0.0.1)  -p <port>          Server port (default 6379)  -s <socket>        Server socket (overrides host and port)  -c <clients>       Number of parallel connections (default 50)  -n <requests>      Total number of requests (default 10000)  -d <size>          Data size of SET/GET value in bytes (default 2)  -k <boolean>       1=keep alive 0=reconnect (default 1)  -r <keyspacelen>   Use random keys for SET/GET/INCR, random values for SADD    Using this option the benchmark will get/set keys    in the form mykey_rand:000000012456 instead of constant    keys, the <keyspacelen> argument determines the max    number of values for the random number. For instance    if set to 10 only rand:000000000000 - rand:000000000009    range will be allowed.  -P <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).  -q                 Quiet. Just show query/sec values 只显示每秒钟能处理多少请求数结果  --csv              Output in CSV format  -l                 Loop. Run the tests forever 永久测试  -t <tests>         Only run the comma separated list of tests. The test                      names are the same as the ones produced as output.  -I                 Idle mode. Just open N idle connections and wait.
