redis安装(基于Linux)
先下载tar包
命令：wget+网址±P+安装指定目录
wget http://download.redis.io/releases/redis-4.0.1.tar.gz -P /usr/local/install-package/
解压tar包
##解压
tar -zxvf install-package/redis-4.0.1.tar.gz -C /usr/local/
##更改文件夹名
mv redis-4.0.1/ redis
进入redis文件夹
编译
cd redis/
##编译
make
如果报了以下错误
这是由于系统没有安装gcc环境，因此在进行编译时才会出现上面提示，当安装好gcc后再进行编译时，上面错误提示将消失。
MAKE hiredis
cd hiredis && make static
make[3]: 进入目录“/usr/local/redis/deps/hiredis”
gcc -std=c99 -pedantic -c -O3 -fPIC -Wall -W -Wstrict-prototypes -Wwrite-strings -g -ggdb net.c
make[3]: gcc：命令未找到
make[3]: *** [net.o] 错误 127
make[3]: 离开目录“/usr/local/redis/deps/hiredis”
make[2]: *** [hiredis] 错误 2
make[2]: 离开目录“/usr/local/redis/deps”
make[1]: [persist-settings] 错误 2 (忽略)
CC adlist.o
/bin/sh: cc: 未找到命令
make[1]: *** [adlist.o] 错误 127
make[1]: 离开目录“/usr/local/redis/src”
make: *** [all] 错误 2
下载gcc并重新make
yum -y install gcc automake autoconf libtool make
如果再报以下错误
[root@localhost redis]# make
cd src && make all
make[1]: 进入目录“/usr/local/redis/src”
CC Makefile.dep
make[1]: 离开目录“/usr/local/redis/src”
make[1]: 进入目录“/usr/local/redis/src”
CC adlist.o
In file included from adlist.c:34:0:
zmalloc.h:50:31: 致命错误：jemalloc/jemalloc.h：没有那个文件或目录
#include
^
编译中断。
make[1]: *** [adlist.o] 错误 1
make[1]: 离开目录“/usr/local/redis/src”
make: *** [all] 错误 2
重新编译
make MALLOC=libc
此时进入到src目录下，进行测试
命令：make test
如果报以下错误
[root@localhost src]# make test
CC Makefile.dep
You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] 错误 1
TCL（Tool Command Language）工具脚本语言，是Linux内的一种语言包。，这里需要先安装tcl。
##下载
wget https://sourceforge.net/projects/tcl/files/Tcl/8.6.8/tcl8.6.8-src.tar.gz -P /usr/local/install-package/
##解压
tar -zxvf /usr/local/install-package/tcl8.6.8-src.tar.gz -C /usr/local/
##进入TCL目录
cd tcl8.6.8/
##进入unix目录
cd unix/
##执行
./configure
##编译
make
##安装
make install
##再次进行测试
cd /usr/local/redis/src/
make test
##执行结束就会出现一大堆绿色的，表示测试成功
\o/ All tests passed without errors!
Cleanup: may take some time... OK
安装
**命令：make PREFIX=/usr/local/redis install **
[root@localhost src]# make PREFIX=/usr/local/redis install
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
再进行查看
[root@localhost redis]# cd ../
[root@localhost redis]# ls
00-RELEASENOTES CONTRIBUTING INSTALL README.md runtest-cluster src
bin COPYING Makefile redis.conf runtest-sentinel tests
BUGS deps MANIFESTO runtest sentinel.conf utils
[root@localhost redis]# cd bin/
[root@localhost bin]# ls
##多了几个命令工具⬇⬇⬇
redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
至此，redis已全部安装完成，接下来是启动
方式一：前端启动
**命令：./redis-server **
##进入bin目录下执行命令
[root@localhost bin]# ./redis-server

这样已经启动完了，但是这属于前端启动，控制台不能进行任何操作，只能ctrl+c退出启动
方式二：后端启动
##编辑redis.conf
vi redis.conf
## 部分内容如下，此时按下键盘的“/”,并输入“daemonize”，定位到“daemonize no”，按下字母“i”表示编辑，将其改为yes，然后按“Esc”，再按出英文的“:”，输入“wq”,表示保存并退出，回车
# Redis configuration file example.
#
# Note that in order to read the configuration file, Redis must be
# started with the file path as first argument:
#
# ./redis-server /path/to/redis.conf
# Note on units: when memory size is needed, it is possible to specify
# it in the usual form of 1k 5GB 4M and so forth:
编辑完成后，再次启动
命令：./bin/redis-server ./redis.conf
## 执行命令
[root@localhost redis]# ./bin/redis-server ./redis.conf
21959:C 11 Jul 02:04:33.230 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
21959:C 11 Jul 02:04:33.230 # Redis version=4.0.1, bits=64, commit=00000000, modified=0, pid=21959, just started
21959:C 11 Jul 02:04:33.230 # Configuration loaded
我们来看下后台是否已启动redis
命令：ps -ef | grep -i redis
## 输入命令查询是否已启动
[root@localhost ~]# ps -ef | grep -i redis
root 21960 1 0 02:04 ? 00:00:00 ./bin/redis-server 127.0.0.1:6379
root 21966 1560 0 02:06 pts/0 00:00:00 grep --color=auto -i redis
既然会了开启，那么也要会关闭
[root@localhost redis]# ./bin/redis-cli shutdown
安装完了，那就来简单的测试下吧
[root@localhost redis]# ./bin/redis-cli
