Redis的安装与配置

CentOS6.4安装配置redis: http://www.centoscn.com/image-text/config/2015/0728/5928.html

新建redis用户，并给以redis sudo权限，下载redis：

[redis@zabbix Downloads]$ ls
redis-3.0.5  redis-3.0.5.tar.gz
[redis@zabbix Downloads]$ tar -zxvf redis-3.0.5.tar.gz
[redis@zabbix Downloads]$ cd redis-3.0.5/
[redis@zabbix redis-3.0.5]$ ls
00-RELEASENOTES  CONTRIBUTING  deps     Makefile   README      runtest          runtest-sentinel  src    utils
BUGS             COPYING       INSTALL  MANIFESTO  redis.conf  runtest-cluster  sentinel.conf     tests

###编译测试安装

[redis@zabbix redis-3.0.5]$ make 

Hint: It's a good idea to run 'make test' ;)
make[1]: Leaving directory `/home/redis/Downloads/redis-3.0.5/src'
[redis@zabbix redis-3.0.5]$ sudo make test
\o/ All tests passed without errors!

Cleanup: may take some time... OK
make[1]: Leaving directory `/home/redis/Downloads/redis-3.0.5/src'

##安装到指定文件夹

[redis@zabbix redis-3.0.5]$ sudo make PREFIX=/usr/local/redis-3.0.5 install
cd src && make install
make[1]: Entering directory `/home/redis/Downloads/redis-3.0.5/src'

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

    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
make[1]: Leaving directory `/home/redis/Downloads/redis-3.0.5/src'
[redis@zabbix redis-3.0.5]$ ls /usr/local/redis-3.0.5/
bin
[redis@zabbix redis-3.0.5]$ cd bin
bash: cd: bin: No such file or directory
[redis@zabbix redis-3.0.5]$ ls /usr/local/redis-3.0.5/bin/
redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis-sentinel  redis-server

##建立软连接文件夹

[redis@zabbix redis-3.0.5]$ sudo ln -s /usr/local/redis-3.0.5/ /usr/local/redis
[redis@zabbix redis-3.0.5]$ ls /usr/local/redis
bin
[redis@zabbix redis-3.0.5]$ ls /usr/local/redis/bin/
redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis-sentinel  redis-server

###添加redis环境变量

[redis@zabbix redis-3.0.5]$ su - root
Password: 
Last login: Mon Dec 19 17:52:07 CST 2016 on pts/0
[root@zabbix ~]# echo 'PATH=$PATH:/usr/local/redis/bin' >> /etc/profile
[root@zabbix ~]# source /etc/profile
[root@zabbix ~]# tail -f /etc/profile
            . "$i"
        else
            . "$i" >/dev/null
        fi
    fi
done

unset i
unset -f pathmunge
PATH=$PATH:/usr/local/redis/bin
^C
[root@zabbix ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/redis/bin

[root@zabbix ~]# su - redis 
Last login: Mon Dec 19 17:47:48 CST 2016 on :0
[redis@zabbix ~]$ which redis-server
/usr/local/redis/bin/redis-server

####配置redis配置文件

[redis@zabbix ~]$ sudo mkdir /usr/local/redis/conf
[redis@zabbix ~]$ sudo cp /home/redis/Downloads/redis-3.0.5/redis.conf /usr/local/redis/conf/
[redis@zabbix ~]$ ls /usr/local/redis/conf/
redis.conf
[redis@zabbix ~]$ ls -al /usr/local/redis/conf/
total 44
drwxr-xr-x 2 root root    23 Dec 19 18:17 .
drwxr-xr-x 4 root root    27 Dec 19 18:16 ..
-rw-r--r-- 1 root root 41560 Dec 19 18:17 redis.conf

####修改系统配置文件

[redis@zabbix ~]$ exit
logout
[root@zabbix ~]# sudo echo vm.overcommit_memory=1 >> /etc/sysctl.conf 
[root@zabbix ~]# tail -f /etc/sysctl.conf 
# System default settings live in /usr/lib/sysctl.d/00-system.conf.
# To override those settings, enter new settings here, or in an /etc/sysctl.d/<name>.conf file
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
vm.overcommit_memory=1

[root@zabbix ~]# sysctl vm.overcommit_memory=1
vm.overcommit_memory = 1

使用数字含义：

0，表示内核将检查是否有足够的可用内存供应用进程使用；如果有足够的可用内存，内存申请允许；否则，内存申请失败，并把错误返回给应用进程。

1，表示内核允许分配所有的物理内存，而不管当前的内存状态如何。

2，表示内核允许分配超过所有物理内存和交换空间总和的内存

###编辑redis启动脚本，

root@zabbix ~]# vim redis.sh

###添加可执行权限

[root@zabbix ~]# chmod 744 redis.sh

###具体内容如下

[root@zabbix ~]# cat redis.sh 
 #!/bin/bash
# chkconfig: 2345 50 30
#
# description: Redis service
#
#Script:Redis command
 
Redisserver=/usr/local/redis/bin/redis-server
Rediscli=/usr/local/redis/bin/redis-cli
Redisconf=/usr/local/redis/conf/redis.conf
 
function_start()
{
    printf "start redis-server..."
    $Redisserver $Redisconf &>/dev/null  & 
    if [ $? -eq 0 ];then
        echo "runing"
    fi
}
 
function_stop()
{
    printf "stop redis-server..."
    $Rediscli -p 6379 shutdown
    if [ $? -eq 0 ];then
        echo "stop"
    fi
}
 
function_restart()
{
    function_start
    function_stop
}
 
function_kill()
{
    killall redis-server
}
 
function_status()
{
    a=`ps -A|grep "redis-server\>" -c`
    if [ $a -ge 1 ];then
        echo -e "The Redis is [\e[0;32;5m runing \e[0m]"
    else
        echo -e "The Redis is [\e[0;31;5m not run \e[0m]"
    fi
}
 
case "$1" in
        start)
                function_start
                ;;
        stop)
                function_stop
                ;;
        restart)
                function_stop
                function_start
                ;;
        kill)
                function_kill
                ;;
        status)
                function_status
                ;;
              *)
              echo "Usage: /etc/init.d/redis {start|stop|restart|kill|status}"
             
esac
 
exit

###启动redis

[root@zabbix ~]# ./redis.sh start
start redis-server...runing

###查看redis是否启动

[root@zabbix ~]# netstat -ntlp | grep redis
tcp        0      0 0.0.0.0:6379            0.0.0.0:*               LISTEN      11979/redis-server  
tcp6       0      0 :::6379                 :::*                    LISTEN      11979/redis-server 
[root@zabbix ~]# ps -ef  |grep 6379
root      11979      1  0 18:27 pts/0    00:00:00 /usr/local/redis/bin/redis-server *:6379

测试连接：

[root@zabbix ~]# redis-cli 
127.0.0.1:6379> set name donald
OK
127.0.0.1:6379> get name
"donald"
127.0.0.1:6379> exit

###关闭redis

[root@zabbix ~]# ./redis.sh stop
stop redis-server...stop
[root@zabbix ~]# netstat -ntlp | grep redis
[root@zabbix ~]# ps -ef  |grep 6379
root      12147  11853  0 18:34 pts/0    00:00:00 grep --color=auto 6379

针对开启redis验证的情况，关闭可以使用如下命令，我们假设验证密码为redis：

redis-cli -a redis shutdown
