redis的linux安装

1.下载安装包

[root@localhost opt]# yum install wget
[root@localhost opt]# wget http://download.redis.io/releases/redis-4.0.13.tar.gz

2.解压安装包

[root@localhost opt]# tar xzf redis-4.0.13.tar.gz
[root@localhost opt]# ls

3.切换到安装目录

[root@localhost opt]# cd redis-4.0.13
[root@localhost redis-4.0.13]# ls

4.编译安装

[root@localhost redis-4.0.13]# make

5.启动redis服务

[root@localhost redis-5.0.3]# src/redis-server redis.conf

6.添加环境变量

[root@localhost src]# vi ~/.bash_profile

# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs
export REDIS_HOME=/opt/redis-5.0.3/
export PATH=$PATH:$REDIS_HOME/src

#PATH=$PATH:$HOME/bin
#export PATH

7.使环境变量生效

source ~/.bash_profile

8.测试，在任何位置登录redis

[root@localhost ~]# redis-server
[root@localhost ~]# redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set name apollo
OK
127.0.0.1:6379> get name
"apollo"

9.启动redis客户端

#1.登录本机redis
[root@localhost redis-5.0.3]# src/redis-cli
#2.指定服务器ip（不指定时，默认本机）
[root@localhost redis-5.0.3]# src/redis-cli -h 127.0.0.1
#3.指定端口（不指定时，默认6379）
redis-cli -h 127.0.0.1 -p 6378

10. 安装过程遇到问题

1.若出现如下提示，则说明未安装gcc,使用命令安装yum -y install gcc gcc-c++ libstdc++-devel

[root@localhost redis-4.0.11]# make
cd src && make all
make[1]: Entering directory `/root/redis-4.0.11

/src‘ CC adlist.o /bin/sh: cc: command not found make[1]: *** [adlist.o] Error 127 make[1]: Leaving directory `/root/redis-2.8.17/src‘ make: *** [all] Error 2

2.若出现如下提示，则将make改为make MALLOC=libc，推测是因为编译库的问题。

[root@localhost redis-4.0.11]# make
cd src && make all
make[1]: Entering directory `/root/redis-2.8.17/src‘
    CC adlist.o
In file included from adlist.c:34:
zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory
zmalloc.h:55:2: error: #error "Newer version of jemalloc required"
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/root/redis-2.8.17/src‘
make: *** [all] Error 2
