redis的下载与安装（linux版）

redis的下载与安装（linux版）

1.下载路径

https://redis.io/download

2.上传到linux

3.进入解压之后的redis，并且make && make install

4.安装成功之后，进入Redis的src目录

启动服务端：./redis-server

 启动客户端：./redis-cli

 启动之后输入 ping 回复pong 表明成功

安装过程中遇到的问题：

 解决方案：升级到最新的gcc:

[root@localhost redis-6.0.1]# gcc -v                             
[root@localhost redis-6.0.1]# yum -y install centos-release-scl  
[root@localhost redis-6.0.1]# yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
[root@localhost redis-6.0.1]# scl enable devtoolset-9 bash
[root@localhost redis-6.0.1]# echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

解决方案：

替换yum源：

[base]
name=Base
baseurl=https://mirrors.aliyun.com/centos/7/os/x86_64/
enabled=1
[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/7/x86_64/
enabled=1

替换为：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#

[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates
[updates]
name=CentOS-$releasever - Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

再次编译即可！

在后台运行redis:

redis-server --daemonize yes

客户端远程连接redis服务器：
-h 远程服务器ip，-p远程服务器端口(redus服务器默认占用端口6379），-a远程服务器密码
redis-cli -h 192.168.26.38 -p 6379 -a waftest

注意，如果要启用远程服务器连接redis，需要在redis服务器中，/etc/redis.conf中，修改以下两处配置：

 redis服务器配置文件需要，存放到：/etc/下，启动redis服务器命令如下：

./redis-server /etc/redis.conf

当执行：./redis-server /etc/redis.conf命令之后，redis服务器没有起来时，应该是端口被占用了

执行：ps  -aux |grep redis 查看占用的进程pid

执行：kill  -9 pid 杀掉该进程；然后再重新启用该进程。

 redis服务器，如果需要远程连接：需要开发6379端口：

查看开发端口：

firewall-cmd --list-ports
关闭防火墙：

systemctl stop firewalld

添加端口：

firewall-cmd add-tcp=port=6379/tcp --permanent

重启防护墙

firewall-cmd --reload
