Centos7 源码安装 Redis 5.0

下载源码

浏览器打开 https://redis.io/download 在 Other versions 下面找到 5.0 的版本，这里一般只提供一个最新的稳定版。右键 》 复制链接地址。

我这里复制到的是 https://download.redis.io/releases/redis-5.0.10.tar.gz

mkdir -p /root/downloads
cd /root/downloads
wget https://download.redis.io/releases/redis-5.0.10.tar.gz

卸载 yum 安装的 Redis（如果之前用 yum 安装过的话）

# 先停止服务
systemctl stop redis  
# 卸载
yum remove redis

编译安装

cd /root/downloads
# 解压
tar -zxvf redis-5.0.10.tar.gz
cd redis-5.0.10
# 编译，需要点时间
make
# 编译完成后安装到 /usr/local/redis
make PREFIX=/usr/local/redis install

# 创建到快捷方式
ln -s /usr/local/redis/bin/redis-server /usr/bin/
ln -s /usr/local/redis/bin/redis-cli /usr/bin/

配置

# 将配置文件放到 /etc/redis.conf
cp /root/downloads/redis-5.0.10/redis.conf /etc/redis.conf

# 进入编辑模式
vi /etc/redis.conf 

bind 127.0.0.1 192.168.0.128               #监听ip，多个ip用空格分隔
daemonize yes                     #允许后台启动
logfile /var/log/redis/redis.log  #日志路径
dir /data/redis/6379              #快照数据存储
requirepass 123456              #设置连接密码


# 创建目录
mkdir -p /var/log/redis
mkdir -p /data/redis/6379  # 存放快照 dump.rdb

# 更改权限
useradd redis
chown redis.redis /var/log/redis
chown redis.redis /data/redis/6379

启动配置

测试

# 修改下关闭脚本的权限
chmod +x /usr/libexec/redis-shutdown
# 测试启动
systemctl start redis
# 测试重启，这里应该比较顺滑的重启好，如果等待超过 5 秒，肯定是有问题
systemctl restart redis
# 设置开机自启动
systemctl enable redis

单机器 Redis 服务多开

新增服务和端口

复制一份到 /etc/redis_6380.conf，并编辑

# 下面这些不能跟原有的打架
pidfile /var/run/redis_6380.pid
port                     6380
logfile                  /var/log/redis/redis_6380.log
dir                      /data/redis/redis/6380

创建目录

mkdir -p /data/redis/redis/6380
chown redis.redis /data/redis/6380

设置新增的 Redis 开机自启

主从配置(有需要再配置)

主库在上面基础上修改配置 /etc/redis.conf

requirepass 123456              #设置master连接密码，slave可省略

从库在上面基础上修改配置 /etc/redis.conf

replicaof 192.168.30.128 6379  # 主库的 ip port  

masterauth 123456   #slave连接master密码，master可省略
requirepass 123456  #设置master连接密码，slave可省略，但是建议跟主库一样的密码

全部重启后，查看状态
