centos编译安装redis

redis下载地址，下载自己需要的版本： https://redis.io/download

我使用的版本是3.0

mv redis-3.0.7 /usr/local/redis
cd /usr/local/redis/
yum -y install gcc-c++
make MALLOC=libc  && make install
redis-server /usr/local/redis/redis.conf

便可以正常启动

make 过程中需要使用make MALLOC=libc命令，否则会出现以下错误

make[1]: Entering directory /usr/local/redis/src'
CC adlist.o
在包含自 adlist.c：34 的文件中:
zmalloc.h:50:31: 错误：jemalloc/jemalloc.h：没有那个文件或目录
zmalloc.h:55:2: 错误：#error "Newer version of jemalloc required"
make[1]: *** [adlist.o] 错误 1
make[1]: Leaving directory/usr/local/redis/src’
make: * [all] 错误 2

但是我们实际使用的话这样挺不方便的，一来无法使用service命令进快速启动， 二来也无法开机自启动

看到以上信息便确定完全成功

生产环境中需要设置Redis最大占用内存，以1GB为例

# In short... if you have slaves attached it is suggested that you set a lower
# limit for maxmemory so that there is some free RAM on the system for slave
# output buffers (but this is not needed if the policy is 'noeviction').
#
# maxmemory <bytes>
