Linux系统安装Redis

一、下载redis

下载地址：

英文版：https://redis.io/download

中文版：www.redis.cn/download.html

下载redis安装包，上传到linux目录下。本次安装的是redis-3.0.7.tar.gz。

[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz  redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]# 
[root@xiaohao-db01 vnum]#

二、安装redis

1、解压redis-3.0.7.tar.gz

解压命令：tar -zxvf redis-3.0.7.tar.gz

解压后可见redis目录：redis-3.0.7

[root@xiaohao-db01 vnum]# tar -zxvf redis-3.0.7.tar.gz^C
[root@xiaohao-db01 vnum]# 
[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz  redis-3.0.7  redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]#

2、编译redis解压后文件。

进入目录redis-3.0.7，执行make命令。

[root@xiaohao-db01 vnum]# 
[root@xiaohao-db01 vnum]# cd redis-3.0.7
[root@xiaohao-db01 redis-3.0.7]# make
cd src && make all
make[1]: Entering directory `/vnum/redis-3.0.7/src'
rm -rf redis-server redis-sentinel redis-cli redis-benchmark redis-check-dump redis-check-aof *.o *.gcda *.gcno *.gcov redis.info lcov-html
(cd ../deps && make distclean)
make[2]: Entering directory `/vnum/redis-3.0.7/deps'
(cd hiredis && make clean) > /dev/null || true
(cd linenoise && make clean) > /dev/null || true
(cd lua && make clean) > /dev/null || true
(cd jemalloc && [ -f Makefile ] && make distclean) > /dev/null || true
(rm -f .make-*)
make[2]: Leaving directory `/vnum/redis-3.0.7/deps'
(rm -f .make-*)
echo STD=-std=c99 -pedantic >> .make-settings
echo WARN=-Wall -W >> .make-settings
echo OPT=-O2 >> .make-settings
echo MALLOC=jemalloc >> .make-settings
echo CFLAGS= >> .make-settings

编译过程显示内容老长，编译成功，最后一般显示如下：

    LINK redis-check-dump
    CC redis-check-aof.o
    LINK redis-check-aof

Hint: It's a good idea to run 'make test' ;)

make[1]: Leaving directory `/vnum/redis-3.0.7/src'

3、安装redis文件。

进入redis-3.0.7/src目录，执行make install命令。

[root@xiaohao-db01 redis-3.0.7]# 
[root@xiaohao-db01 redis-3.0.7]# ls
00-RELEASENOTES  CONTRIBUTING  deps     Makefile   README      runtest          runtest-sentinel  src    utils
BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests
[root@xiaohao-db01 redis-3.0.7]# cd src
[root@xiaohao-db01 src]# make install

Hint: It's a good idea to run 'make test' ;)

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
[root@xiaohao-db01 src]#

4、在目录redis-3.0.7新建文件夹redis，将redis相关的配置文件拷贝到该目录下。

这么做是把redis相关执行文件放在专门的相同目录下，方便操作。可选。

[root@xiaohao-db01 redis-3.0.7]# mkdir redis
[root@xiaohao-db01 redis-3.0.7]# ls
00-RELEASENOTES  CONTRIBUTING  deps     Makefile   README  redis.conf  runtest-cluster   sentinel.conf  tests
BUGS             COPYING       INSTALL  MANIFESTO  redis   runtest     runtest-sentinel  src            utils
[root@xiaohao-db01 redis-3.0.7]# 
[root@xiaohao-db01 redis-3.0.7]# cp -a redis.conf redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-cli /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-server /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-check-dump /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-check-aof /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-sentinel /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# 
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-trib.rb /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/mkreleasehdr.sh /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]# cp -a /vnum/redis-3.0.7/src/redis-benchmark /vnum/redis-3.0.7/redis
[root@xiaohao-db01 redis-3.0.7]#

拷贝完成后，在redis目录如下：

[root@xiaohao-db01 redis-3.0.7]# cd ..
[root@xiaohao-db01 vnum]# ls
keepalived-1.2.22.tar.gz  redis-3.0.7  redis-3.0.7.tar.gz
[root@xiaohao-db01 vnum]# cd redis-3.0.7
[root@xiaohao-db01 redis-3.0.7]# cd redis
[root@xiaohao-db01 redis]# ls
mkreleasehdr.sh  redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis.conf  redis-sentinel  redis-server  redis-trib.rb
[root@xiaohao-db01 redis]#

三、测试redis。

1、启动redis.

启动命令： /vnum/redis-3.0.7/redis/redis-server /vnum/redis-3.0.7/redis/redis.conf &

建议先修改配置文件，默认后台启动:daemonize yes

[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# /vnum/redis-3.0.7/redis/redis-server /vnum/redis-3.0.7/redis/redis.conf
                _._

  `-._    `-._`-.__.-'_.-'    _.-'                                   
      `-._    `-.__.-'    _.-'                                       
          `-._        _.-'                                           
              `-.__.-'                                               

26183:M 19 Apr 14:58:16.466 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
26183:M 19 Apr 14:58:16.466 # Server started, Redis version 3.0.7

26183:M 19 Apr 14:58:16.468 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis.

Redis must be restarted after THP is disabled.

2、登陆redis，测试读写数据。

登陆命令：

/vnum/redis-3.0.7/redis/redis-cli -h 127.0.0.1 -p 6379

/vnum/redis-3.0.7/redis/redis-cli -p 6379

登录后，使用get,set命令简单测试下：

[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# /vnum/redis-3.0.7/redis/redis-cli -h 127.0.0.1 -p 6379
127.0.0.1:6379> 
127.0.0.1:6379> 
127.0.0.1:6379> set test "haha"
OK
127.0.0.1:6379> get "haha"
(nil)
127.0.0.1:6379> get "test"
"haha"
127.0.0.1:6379> del "test"
(integer) 1
127.0.0.1:6379> get "test"
(nil)
127.0.0.1:6379>

3、关闭redis。

关闭命令：/vnum/redis-3.0.7/redis/redis-cli -p 6379 shutdown

[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# ps -ef | grep redis
root     26229 20949  0 14:59 pts/0    00:00:00 /vnum/redis-3.0.7/redis/redis-server *:6379                            
root     26447 20949  0 15:02 pts/0    00:00:00 grep redis
[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# /vnum/redis-3.0.7/redis/redis-cli -p 6379 shutdown
26229:M 19 Apr 15:02:57.769 # User requested shutdown...
26229:M 19 Apr 15:02:57.769 * Saving the final RDB snapshot before exiting.
26229:M 19 Apr 15:02:57.772 * DB saved on disk
26229:M 19 Apr 15:02:57.772 # Redis is now ready to exit, bye bye...
[1]+  Done                    /vnum/redis-3.0.7/redis/redis-server /vnum/redis-3.0.7/redis/redis.conf
[root@xiaohao-db01 redis]# 
[root@xiaohao-db01 redis]# ps -ef | grep redis
root     26450 20949  0 15:03 pts/0    00:00:00 grep redis
[root@xiaohao-db01 redis]#

四、redis的配置。
