第二步:解压压缩包
tar -zxvf redis-4.0.6.tar.gz
[root@iZwz991stxdwj560bfmadtZ local]# tar -zxvf redis-4.0.6.tar.gz
第三步:yum安装gcc依赖
yum install gcc
[root@iZwz991stxdwj560bfmadtZ local]# yum install gcc
遇到选择,输入y即可
第四步:跳转到redis解压目录下
cd redis-4.0.6
[root@iZwz991stxdwj560bfmadtZ local]# cd redis-4.0.6
第五步:编译安装
make MALLOC=libc
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# make MALLOC=libc
将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录
cd src && make install
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src && make install
CC Makefile.dep
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
先切换到redis src目录下
[root@iZwz991stxdwj560bfmadtZ redis-4.0.6]# cd src
1、直接启动redis
./redis-server
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server

18685:C 13 Dec 12:56:12.507 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

如上图:redis启动成功,但是这种启动方式需要一直打开窗口,不能进行其他操作,不太方便。
按 ctrl + c可以关闭窗口。
2、以后台进程方式启动redis
第一步:修改redis.conf文件
将
daemonize no
修改为
daemonize yes
第二步:指定redis.conf文件启动
./redis-server /usr/local/redis-4.0.6/redis.conf
[root@iZwz991stxdwj560bfmadtZ src]# ./redis-server /usr/local/redis-4.0.6/redis.conf
18713:C 13 Dec 13:07:41.109 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
18713:C 13 Dec 13:07:41.109 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18713, just started
18713:C 13 Dec 13:07:41.109 # Configuration loaded
第三步:关闭redis进程
首先使用ps -aux | grep redis查看redis进程
[root@iZwz991stxdwj560bfmadtZ src]# ps -aux | grep redis
root 18714 0.0 0.1 141752 2008 ? Ssl 13:07 0:00 ./redis-server 127.0.0.1:6379
root 18719 0.0 0.0 112644 968 pts/0 R+ 13:09 0:00 grep --color=auto redis
使用kill命令杀死进程
[root@iZwz991stxdwj560bfmadtZ src]# kill -9 18714
3、设置redis开机自启动
1、在/etc目录下新建redis目录
mkdir redis
[root@iZwz991stxdwj560bfmadtZ etc]# mkdir redis
2、将/usr/local/redis-4.0.6/redis.conf 文件复制一份到/etc/redis目录下,并命名为6379.conf
[root@iZwz991stxdwj560bfmadtZ redis]# cp /usr/local/redis-4.0.6/redis.conf /etc/redis/6379.conf
3、将redis的启动脚本复制一份放到/etc/init.d目录下
[root@iZwz991stxdwj560bfmadtZ init.d]# cp /usr/local/redis-4.0.6/utils/redis_init_script /etc/init.d/redisd
4、设置redis开机自启动
先切换到/etc/init.d目录下
然后执行自启命令
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
service redisd does not support chkconfig
看结果是redisd不支持chkconfig
解决方法:
使用vim编辑redisd文件,在第一行加入如下两行注释,保存退出
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
注释的意思是,redis服务必须在运行级2,3,4,5下被启动或关闭,启动的优先级是90,关闭的优先级是10。
再次执行开机自启命令,成功
[root@iZwz991stxdwj560bfmadtZ init.d]# chkconfig redisd on
现在可以直接已服务的形式启动和关闭redis了
启动:
service redisd start
[root@izwz991stxdwj560bfmadtz ~]# service redisd start
Starting Redis server...
2288:C 13 Dec 13:51:38.087 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
2288:C 13 Dec 13:51:38.087 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=2288, just started
2288:C 13 Dec 13:51:38.087 # Configuration loaded
关闭:
service redisd stop
[root@izwz991stxdwj560bfmadtz ~]# service redisd stop
Stopping ...
Redis stopped

2、http://blog.csdn.net/gxw19874/article/details/51992125
如果出现如下问题:
[root@iZwz991stxdwj560bfmadtZ ~]# service redisd start
/var/run/redis_6379.pid exists, process is already running or crashed
在安装redis的过程中,启动service redisd start时报错
/var/run/redis_6379.pid exists, process is already running or crashed
解决方案:
执行命令:
rm -rf /var/run/redis_6379.pid
然后重新执行 service redisd start
问题解决!
在服务器上,这里以linux服务器为例,为redis配置密码。
1.第一种方式 (当前这种linux配置redis密码的方法是一种临时的,如果redis重启之后密码就会失效,)
(1)首先进入redis,如果没有开启redis则需要先开启:
[root@iZ94jzcra1hZ bin]# redis-cli -p 6379
127.0.0.1:6379>
(2)查看当前redis有没有设置密码:
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) ""
(3)为以上显示说明没有密码,那么现在来设置密码:
127.0.0.1:6379> config set requirepass abcdefg
OK
127.0.0.1:6379>
(4)再次查看当前redis就提示需要密码:
127.0.0.1:6379> config get requirepass
(error) NOAUTH Authentication required.
127.0.0.1:6379>
2.第二种方式 (永久方式)
需要永久配置密码的话就去redis.conf的配置文件中找到requirepass这个参数,如下配置:
修改redis.conf配置文件
# requirepass foobared
requirepass 123 指定密码123
保存后重启redis就可以了
连接redis
1.redis-cli连接redis
[root@iZ2ze3zda3caeyx6pn7c5zZ bin]# redis-cli
127.0.0.1:6379> keys *
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123 //指定密码
OK
127.0.0.1:6379> keys *
1) "a"
2) "cit"
3) "clist"
4) "1"
127.0.0.1:6379>
3.1 配置redis.conf
将 bind 127.0.0.1 使用#注释掉,改为# bind 127.0.0.1(bind配置的是允许连接的ip,默认只允许本机连接;若远程连接需注释掉,或改为0.0.0.0)
将 protected-mode yes 改为 protected-mode no(3.2之后加入的新特性,目的是禁止公网访问redis cache,增强redis的安全性)
将 requirepass foobared 注释去掉,foobared为密码,也可修改为别的值(可选,建议设置)
3.2 设置iptables规则,允许外部访问6379端口
iptables -I INPUT 1 -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
临时生效,重启后失效。若想永久生效,请参考另一篇文章:http://www.cnblogs.com/jinjiyese153/p/8600855.html
3.3 启动redis,并指定配置文件
./redis-server ../redis.conf
