CentOS 7 安装Redis

CentOS 7 安装Redis

1. 安装依赖等

    [root@localhost ~]# yum install -y wget gcc
   

2. 下载redis-5.0.3.tar.gz并安装

    [root@localhost ~]# wget http://download.redis.io/releases/redis-5.0.3.tar.gz
    [root@localhost ~]# tar -zxvf redis-5.0.3.tar.gz
    [root@localhost ~]# cd redis-5.0.3
    [root@localhost redis-5.0.3]# make MALLOC=libc
   

3. 安装Redis服务

    [root@localhost redis-5.0.3]# ./utils/install_server.sh

    Successfully added to chkconfig!
    Successfully added to runlevels 345!
    Starting Redis server...
    Installation successful!

修改服务名称

    [root@localhost ~]# mv /etc/init.d/redis_6379 /etc/init.d/redis

4. 配置Redis.conf

    [root@localhost ~]# vi /etc/redis/6379.conf
   

配置Redis.conf

    # bind增加当前服务器内网IP
    bind 10.0.0.120 127.0.0.1 
    
    # 将backlog增大
    tcp-backlog 2000    
    
    # 关闭存盘策略
    # save 900 1
    # save 300 10
    # save 60 10000
    
    # 修改showlog策略
    slowlog-log-slower-than 5000
    slowlog-max-len 500
    
    # 关闭hash-max-ziplist压缩
    # hash-max-ziplist-entries 512
    # hash-max-ziplist-value 64

5. 重启服务

    [root@localhost ~]# service redis restart
    Stopping ...
    Redis stopped
    Starting Redis server...
   

6. 测试服务是否正常运行

    [root@localhost ~]# redis-cli
    127.0.0.1:6379> set a 123456
    OK
    127.0.0.1:6379> get a
    "123456"
    127.0.0.1:6379> exit
   

7. 防火墙

    [root@localhost ~]# vim /etc/sysconfig/iptables
   

在22端口下增加开放6379端口号

    -A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT

重新启动防火墙服务

    [root@localhost ~]# systemctl restart iptables
