linux下centos7.2下安装redis 4.0.6

一、安装redis

第一步:下载redis安装包

wget http://download.redis.io/releases/redis-4.0.6.tar.gz

说明: 复制代码

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

--2020-05-08 12:35:12--  http://download.redis.io/releases/redis-4.0.6.tar.gz

说明: 复制代码

 

第二步:解压压缩包

tar -zxvf redis-4.0.6.tar.gz

[root@localhost home]# tar -zxvf redis-4.0.6.tar.gz

 

第三步:yum安装gcc依赖

yum install gcc

[root@localhost home]# 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@localhost home]# cd redis-4.0.6

 

第五步:编译安装

make MALLOC=libc  

[root@localhost redis-4.0.6]# make MALLOC=libc

 

/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录  cp –rf  就行

cd src && make install

说明: 复制代码

[root@localhost 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

说明: 复制代码

 

二、启动redis的三种方式

 

先切换到redis src目录下

[root@localhost redis-4.0.6]# cd src

 

1、直接启动redis

./redis-server

说明: 复制代码

[root@localhost 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

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  

说明: 复制代码

 

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。

 

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

daemonize no

 

修改为

daemonize yes

 

第二步:指定redis.conf文件启动

1

./redis-server   /usr/local/redis-4.0.6/redis.conf

[root@localhost 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@localhost 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@localhost 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@localhost 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@localhost 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@localhost 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@localhost 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2345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@localhost init.d]# chkconfig redisd on

 

现在可以直接已服务的形式启动和关闭redis

启动:

service redisd start 

[root@localhost ~]# 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1service redisd stop

[root@localhost ~]# service redisd stop

Stopping ...

Redis stopped

 

方法2redis-cli SHUTDOWN

 

三、linux服务器端可以连接而远程无法连接的原因

[root@localhost src]# vim ../redis.conf

protected-mode yes改为protected-mode no(在没有密码的情况下,关闭保护模式)

注释掉bind 127.0.0.1     (取消绑定本地地址)

daemonize no改为daemonize yes   (是否为进程守护,关闭ssh窗口后即是否在后台继续运行)

redis-conf注释掉bind 127.0.0.1     (取消绑定本地地址)

若还不能访问  则开启制定端口号或者关闭防火墙,在这采用关闭防火墙,由于是centos7,防火墙进行了升级

 

systemctl stop firewalld.service           #停止firewall

systemctl disable firewalld.service     #禁止firewall开机启动 

如果出现如下问题:

[root@localhost ~]# service redisd start

/var/run/redis_6379.pid exists, process is already running or crashed

删除redis_6379.pid即可
