7. cd src && make install
8. make[1]:Entering directory `/home/wch/SoftWare/Redis/redis-2.8.22/src'

默认安装路径:/usr/local/bin，只需要使用命令：make install指定安装路径：make PREFIX=/some/other/directory install，注意PREFIX大小写不能变！

2.启动Redis服务

1.启动服务端进入安装路径，可以看到有一个bin目录，进入bin目录，启动Redis服务

1. [wch@localhost bin]$ ll
2. total 15208
3. -rwxr-xr-x.1 wch wch 4574611Oct104:39 redis-benchmark
4. -rwxr-xr-x.1 wch wch 22201Oct104:39 redis-check-aof
5. -rwxr-xr-x.1 wch wch 45411Oct104:39 redis-check-dump
6. -rwxr-xr-x.1 wch wch 4676357Oct104:39 redis-cli
7. lrwxrwxrwx.1 wch wch 12Oct104:39 redis-sentinel -> redis-server
8. -rwxr-xr-x.1 wch wch 6242453Oct104:39 redis-server
9. [wch@localhost bin]$ ./redis-server
10. [13745]01Oct04:45:05.889# Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
11. [13745]01Oct04:45:05.890# You requested maxclients of 10000 requiring at least 10032 max file descriptors.
12. [13745]01Oct04:45:05.890# Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.
13. [13745]01Oct04:45:05.890# Current maximum open files is 1024. maxclients has been reduced to 992 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.

2.使用客户端连接Redis服务

1. [wch@localhost bin]$ ./redis-cli
2. 127.0.0.1:6379> ping
3. PONG
4. 127.0.0.1:6379>set name wch
5. OK
6. 127.0.0.1:6379> get name
7. "wch"
8. 127.0.0.1:6379>
