centos7下安装redis以及本地连接注意事项

安装

1.上传安装包进行解压

[root@node01 ~]# mkdir -p /opt/software
[root@node01 ~]# cd /opt/software
[root@node01 software]# rz
z waiting to receive.**B0100000023be50
[root@node01 software]# ls
redis  redis-6.2.7  tar.7.2.redis-6.gz
[root@node01 software]# tar zxf tar.7.2.redis-6.gz

2.编译安装

安装需要的C插件

[root@node01 ~]# yum -y install gcc tcl

编译Redis

进入/software/cd /software/redis-6.2.7目录中，编译redis。

[root@node01 ~]# cd /opt/software/redis-6.2.7
[root@node01 redis-6.2.7]# make

创建安装目录安装Redis

#创建安装目录
[root@node01 ~]# mkdir -p /opt/software/redis

#进入redis编译目录，安装redis
[root@node01 ~]# cd /opt/software/redis-6.2.7
[root@node01 redis-6.2.7]# make PREFIX=/opt/software/redis install

注意：现在就可以使用redis了，进入/software/redis/bin下，就可以执行redis命令。

3.开机自启动以及脚本启动

将redis-server链接到/usr/local/bin/目录下，后期加入系统服务时避免报错

[root@node01 ~]# ln -sf /opt/software/redis-6.2.7/src/redis-server /usr/local/bin/

修改服务安装

配置install_server.sh

[root@node01 ~]# cd /opt/software/redis-6.2.7/utils/
[root@node01 ~]# vi install_server.sh

注释掉以下部分

#_pid_1_exe="$(readlink -f /proc/1/exe)"
#if [ "${_pid_1_exe##*/}" = systemd ]
#then
#	echo "This systems seems to use systemd."
#	echo "Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!"
#	exit 1
#fi

执行安装

[root@node01 ~]#  ./install_server.sh

配置环境变量

[root@node01 ~]# vim /etc/profile
export REDIS_HOME=/software/redis
export PATH=$PATH:$REDIS_HOME/bin
#使环境变量生效
[root@node01 ~]# source /etc/profile

启动停止redis服务

[root@node01 utils]# systemctl status redisd 
● redisd.service - LSB: start and stop redis_6379
   Loaded: loaded (/etc/rc.d/init.d/redisd; bad; vendor preset: disabled)

4.需要修改配置文件

4.1 配置是否以守护进程运行

By default Redis does not run as a daemon. Use ‘yes’ if you need it.
Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
When Redis is supervised by upstart or systemd, this parameter has no impact.

daemonize yes

4.2 修改绑定ip

bind 192.168.5.130     # listens on two specific IPv4 addresses
bind 127.0.0.1 ::1              # listens on loopback IPv4 and IPv6
