安装redis（一）单机

环境

    操做系统：centos7

    redis版本：http://download.redis.io/releases/redis-3.2.9.tar.gz

解压安装

[root@localhost softs]# tar -zxvf redis-3.2.9.tar.gz 
[root@localhost softs]# mv redis-3.2.9 redis

这一步是将redis解压后重命名为redis

• 安装编译环境

[root@localhost redis]# yum install -y gcc g++ gcc-c++ make

• 执行安装，先进入解压后的redis目录

[root@localhost redis]# make install

• 初始化redis

[root@localhost redis]# ls

Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] 
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server] 
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

按照默认一直回车便可。

进入/etc/init.d/查看一下文件：

[root@localhost init.d]# ls
functions  netconsole  network  README  redis_6379
[root@localhost init.d]#

在这里有一个redis_6379的文件，如今可使用这个文件来启动或者中止redis

# 启动redis服务
/etc/init.d/redis_6379 start
# 查看进程
netstat -apn|grep redis
# 中止redis服务
/etc/init.d/redis_6379 stop

# 重启redis服务
/etc/init.d/redis_6379 restart

 

• 设置外网访问,编辑 /etc/redis/6379.conf 文件

注释：#bind 127.0.0.1

去掉注释并设置密码： requirepass redis

设置就将redis的密码设置成了redis

使用命令行进入redis

[root@localhost ~]# redis-cli -h 127.0.0.1 -p 6379

注意：若是设置了redis的密码则在使用/etc/init.d/redis_6379 start|stop|restart 时不成功。此时须要修改

/etc/init.d/redis_6379 

PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -p $REDISPORT -h 127.0.0.1 -a redis  shutdown

-a redis 表示redis的密码是字符串"redis"
