篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了CentOS7编译安装Redis5及修改端口设置开机启动相关的知识,希望对你有一定的参考价值。

系统:CentOS7
Redis:5.0.5
获取最新版本redis:https://redis.io/download ,下载Stable版本,当前安装版本5.0.5

一、安装Redis

1、下载redis安装包(安装目录/usr/local/)

[root@iZbp12y6fwj9mup08bgko6Z ~]# cd /usr/local/
[root@iZbp12y6fwj9mup08bgko6Z local]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz

2、解压redis-5.0.5.tar.gz

[root@iZbp12y6fwj9mup08bgko6Z local]# tar -xzf redis-5.0.5.tar.gz

3、进入解压的redis目录,通过make命令进行编译

[root@iZbp12y6fwj9mup08bgko6Z local]# cd redis-5.0.5
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make

4、执行make test验证编译是否成功(可能会报错,但是不要怕一步一步解决错误,直至成功)

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make test
cd src && make test
make[1]: Entering directory `/usr/local/redis-5.0.5/src\'
    CC Makefile.dep
make[1]: Leaving directory `/usr/local/redis-5.0.5/src\'
make[1]: Entering directory `/usr/local/redis-5.0.5/src\'
You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [test] Error 1
make[1]: Leaving directory `/usr/local/redis-5.0.5/src\'
make: *** [test] Error 2

###### 很不巧,我的编译错误了,根据错误提示是tcl的问题,所有我要安装一下tcl,你需要根据你的结果信息来处理

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# yum install -y tcl
......

Complete!
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]#

###### tcl安装完成后重新运行make test

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make test
......
!!! WARNING The following tests failed:

*** [err]: Active defrag big keys in tests/unit/memefficiency.tcl
Expected condition \'$max_latency <= 120\' to be true (258 <= 120)
Cleanup: may take some time... OK
make[1]: *** [test] Error 1
make[1]: Leaving directory `/usr/local/redis-5.0.5/src\'
make: *** [test] Error 2

######此错误是由于所测试的阿里云ECS服务器配置过低造成的延迟太大,可以忽略。

忽略警告,继续安装

6、运行make install命令,将命令安装到/usr/local/bin目录

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make install
cd src && make install
make[1]: Entering directory `/usr/local/redis-5.0.5/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 `/usr/local/redis-5.0.5/src\'
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# 

7、启动服务器

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# redis-server

8、另开一个命令窗口,进行测试,可以看到通过redis-cli命令连接redis之后,输入ping,redis会为我们返回PONG

[root@iZbp12y6fwj9mup08bgko6Z ~]# redis-cli 
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

二、设置redis

1、复制redis配置文件,将redis目录的redis.conf复制到/etc/redis目录下

root@iZbp12y6fwj9mup08bgko6Z ~]# find / -name redis.conf
/usr/local/redis-5.0.5/redis.conf
[root@iZbp12y6fwj9mup08bgko6Z ~]# mkdir /etc/redis
[root@iZbp12y6fwj9mup08bgko6Z ~]# cp /usr/local/redis-5.0.5/redis.conf /etc/redis/redis.conf

2、设置可以远程登录,编辑/etc/redis/redis.conf配置文件,注释掉bind 127.0.0.1,如下图:

3、修改默认端口6379,编辑/etc/redis/redis.conf配置文件,如下图:

同时修改pidfile,将其改为pidfile /var/run/redis_6379.pid,修改目的是为了文件名上的端口和实际端口保持一致,方便通过服务方式启动、停止,如后面设置开机启动

4、设置redis服务后台运行,编辑/etc/redis/redis.conf配置文件,将daemonize设置为yes,如下图

5、设置访问密码,编辑/etc/redis/redis.conf配置文件,去掉requirepass行的注释或添加一行,如下图

6、启动redis并指定配置文件为我们刚才修改的/etc/redis/redis.conf配置文件,服务启动后就不像前面那样输出redis图形信息的内容了。

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# redis-server /etc/redis/redis.conf
21262:C 27 Jun 2020 17:21:47.055 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
21262:C 27 Jun 2020 17:21:47.055 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=21262, just started
21262:C 27 Jun 2020 17:21:47.055 # Configuration loaded
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# 

7、新开一窗口测试链接

[root@iZbp12y6fwj9mup08bgko6Z ~]# redis-cli 
127.0.0.1:6379> ping
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> 

也可以通过-p指定端口访问

[root@iZbp12y6fwj9mup08bgko6Z ~]# redis-cli -p 6379
127.0.0.1:6379> ping
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379>

由于开启了远程访问,所以在其他电脑上也可以访问,通过-h指定ip,-p指定端口:

[iypocket@smac src] ./redis-cli -p 6380 -h 192.168.16.125
192.168.16.125:6379> ping
(error) NOAUTH Authentication required.
192.168.16.125:6379> auth 123456
OK
192.168.16.125:6379> ping
PONG
192.168.16.125:6379>

8、停止服务

三、设置redis开机启动

1、复制开机启动脚本,在redis目录的utils包下,有一个redis_init_script文件,我们复制到/etc/init.d/目录下,并将文件名改为redis。

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# find / -name redis_init_script
/usr/local/redis-5.0.5/utils/redis_init_script
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# cp /usr/local/redis-5.0.5/utils/redis_init_script /etc/init.d/redis

2、(非必须)修改/etc/redis/redis.conf文件名为/etc/redis/6379.conf,此修改非必须,不修改的话可以在步骤3指定配置文件路径

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# mv /etc/redis/redis.conf /etc/redis/6379.conf

3、编辑/etc/init.d/redis启动脚本,脚本说明如下:

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# vim /etc/init.d/redis

说明

4、测试启动脚本,启动服务systemctl start redis,停止服务systemctl stop redis

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# systemctl start redis
[[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# systemctl stop redis

5、设置开机启动

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# chkconfig --add redis

6、重启系统,redis服务即随系统启动。

[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# reboot
