Redis 安装

当前最新release版本：redis-5.0.2.tar.gz

1. 下载安装包

wget http://download.redis.io/releases/redis-5.0.2.tar.gz

2. 解压

tar xzf redis-5.0.2.tar.gz

3. 编译

cd redis-5.0.2
make
make install

4. 定制配置文件

cp /usr/local/redis-5.0.2/redis.conf  /etc/redis/6379.conf
vim /etc/redis/6379.conf

# 使Redis以守护进程模式运行
daemonize yes

# 设置Redis的PID文件位置
pidfile /var/run/redis_6379.pid

# 设置Redis监听的端口号
port 6379

# 设置持久化文件存放位置
dir /var/redis/6379/

# 绑定地址 （远程登陆时，需要注释掉）
# bind 127.0.0.1

# ... 

5. 初始化脚本

cp /usr/local/redis-5.0.2/utils/redis_init_script  /etc/init.d/redis_6379

6. 启动和停止Redis (跳过)

/etc/init.d/redis_6379 start
/etc/init.d/redis_6379 stop

# 考虑到 Redis 有可能正在将内存中的数据同步到硬盘中，强行终止 Redis 进程可能会导致数据丢失。
# 正确停止Redis的方式应该是向Redis发送SHUTDOWN命令，方法为：
redis-cli SHUTDOWN

7. 设置开机启动

# 初始化脚本文件头部第四行的位置，增加下面两行
# chkconfig: 2345 90 10 
# description: Redis is a persistent key-value database
vim /etc/init.d/redis_6379

# 编辑后如下：

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
# as it does use of the /proc filesystem.

                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
    *)
        echo "Please use start or stop as first argument"
        ;;
esac

# 设置开机执行Redis脚本
chkconfig /etc/init.d/redis_6379 on

# 启动和停止Redis
service redis_6379 start
service redis_6379 stop

8. 配置密码后，上面命令会提示" (error) NOAUTH Authentication required."

# 修改/etc/init.d/redis_6379 文件见下：

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
# as it does use of the /proc filesystem.
