在VMware的Linux系统上安装Redis
具体过程如下:
下载,解压和编译:
$ wget
$ tar xzf redis-2.6.14.tar.gz
$ cd redis-2.6.14
$ make
在执行make的时候报错,具体报错信息如下:
zmalloc.o: In function `zmalloc_used_memory':
/usr/local/redis-2.6.14/src/zmalloc.c:223: undefined reference to `__sync_add_and_fetch_4'
collect2: ld returned 1 exit status
make[1]: *** [redis-server] Error 1
make[1]: Leaving directory `/usr/local/redis-2.6.14/src'
make: *** [all] Error 2
网上查了下资料,主要是因为我的linux是32位的,所以会报这个错,解决方案如下:
在make操作的时候加一个执行参数:make CFLAGS="-march=i686"
然后就不报错了。
附:启动并运行Redis
编译的可执行文件在src目录中,使用以下命令运行Redis:
[root@localhost redis-2.6.14]# src/redis-server
启动成功后控制台打印如下信息:
[2918] 03 Jul 09:05:01.011 # Warning: no config file specified, using the default config. In order to specify a config file use src/redis-server /path/to/redis.conf

附2:把Redis作为Linux服务开机启动
这里只提供一种最简单的方式,最好的是通过编写开机启动脚本来做。
如果要开机启动redis,我们需要把redis设置为daemon后台启动(如果不设置为后台启动,则linux启动后图形界面会卡在一个空白的页面),而redis只有1个启动参数,就是redis的配置文件路径。redis的默认配置文件redis.conf位于redis的安装目录下。我们可以把该文件copy到/etc目录下
[root@localhost redis-2.6.14]# cp redis.conf /etc/
