• CentOS7安装Redis


    第一步:下载redis安装包

    wget http://download.redis.io/releases/redis-4.0.6.tar.gz
    [root@iZwz991stxdwj560bfmadtZ local]# wget http://download.redis.io/releases/redis-4.0.6.tar.gz

    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

    已安装的可忽略  yum install gcc

    [root@iZwz991stxdwj560bfmadtZ local]# yum install gcc

    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

    二、启动redis的三种方式

    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 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
    18685:C 13 Dec 12:56:12.507 # Redis version=4.0.6, bits=64, commit=00000000, modified=0, pid=18685, just started
    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
                    _._                                                  
               _.-``__ ''-._                                             
          _.-``    `.  `_.  ''-._           Redis 4.0.6 (00000000/0) 64 bit
      .-`` .-```.  ```/    _.,_ ''-._

     |`-._`-...-` __...-.``-._|'` _.-'|     Port: 6379

      `-._    `-._  `-./  _.-'    _.-'                                   
     |`-._`-._    `-.__.-'    _.-'_.-'|                                  
     |    `-._`-._        _.-'_.-'    |           http://redis.io        
      `-._    `-._`-.__.-'_.-'    _.-'                                   
     |`-._`-._    `-.__.-'    _.-'_.-'|                                  
     |    `-._`-._        _.-'_.-'    |                                  
      `-._    `-._`-.__.-'_.-'    _.-'                                   
          `-._    `-.__.-'    _.-'                                       
              `-._        _.-'                                           
                  `-.__.-'                                               
    
    18685:M 13 Dec 12:56:12.508 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
    18685:M 13 Dec 12:56:12.508 # Server initialized
    18685:M 13 Dec 12:56:12.508 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
    18685:M 13 Dec 12:56:12.508 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
    18685:M 13 Dec 12:56:12.508 * Ready to accept connections

    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 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:

    方法1:service redisd stop

    [root@izwz991stxdwj560bfmadtz ~]# service redisd stop
    Stopping ...
    Redis stopped

    方法2:redis-cli SHUTDOWN
