# Redis 安装

最新版本redis下载地址：https://redis.io/download

# 下载源码并编译

下面以5.0.3版本为例演示从源码下载到安装启动的全过程

wget http://download.redis.io/releases/redis-5.0.3.tar.gz
tar -xzvf redis-5.0.3.tar.gz
cd redis-5.0.3
make # 编译

make 编译过后进入src目录就能看见编译后的 redis 服务程序 redis-server、用于测试的客户端程序 redis-cli

# 启动 redis 服务

下面启动 redis 服务

redis启动成功

# 安装过程中可能碰到的坑

  • 未安装 gcc 服务，导致redis源码编译失败

    解决方案：

    缺啥补啥，通过yum安装 gcc 的服务

    yum install gcc

    安装完以后再次执行 make 命令

  • 源码编译失败，解决完提示的报错问题后，仍无法编译，报错某某目录或文件不存在

    报错信息如下

    [root@106 redis-5.0.3]# make
cd src && make all
make[1]: Entering directory `/data/tools/redis/redis-5.0.3/src'
    CC Makefile.dep
make[1]: Leaving directory `/data/tools/redis/redis-5.0.3/src'
make[1]: Entering directory `/data/tools/redis/redis-5.0.3/src'
    CC adlist.o

make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/data/tools/redis/redis-5.0.3/src'
make: *** [all] Error 2

    改文件或目录可能是上次编译过程中产生的中间文件，执行编译清除命令即可继续向下执行

    • make distclean
    • make clean
