引言
本文转自centos8安装redis，如果其中redis目录不存在，按照命令中路径创建即可，同时注意按照自己的目录，修改响应命令，步骤不再赘述，这里只提一下关于redis配置文件修改的事儿，redis安装配置文件配置。
另外，redis5 我虚拟机上的下载目录：
[root@localhost xgcd]# cd /home/xgcd/ [root@localhost xgcd]# [root@localhost xgcd]# ll total 140048 drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Desktop drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Documents drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Downloads -rw-rw-r--. 1 xgcd xgcd 41182192 Mar 17 05:10 esl-erlang_22.2.8-1_centos_8_amd64.rpm drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Music -rw-rw-r--. 1 xgcd xgcd 87768737 Mar 17 06:35 otp_src_22.2.tar.gz drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Pictures drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Public -rw-rw-r--. 1 xgcd xgcd 12462936 Mar 17 06:00 rabbitmq-server-3.8.3-1.el8.noarch.rpm drwxrwxr-x. 6 root root 4096 Nov 20 01:05 redis-5.0.7 -rw-r--r--. 1 root root 1984203 Nov 20 01:06 redis-5.0.7.tar.gz drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Templates drwxr-xr-x. 2 xgcd xgcd 6 Mar 16 22:31 Videos
配置文件目录：
[root@localhost conf]# cd /usr/local/soft/redis5/conf/ [root@localhost conf]# ll total 64 -rw-r--r--. 1 root root 61794 Mar 20 11:12 redis.conf
配置文件关键项：
bind 127.0.0.1 bind 192.168.81.129 protected-mode yes port 6379 daemonize yes logfile "/usr/local/soft/redis5/log/redis.log" dbfilename dump.rdb dir ./ requirepass 123456
启动并查看状态：
[root@localhost redis5]# ./bin/redis-server /usr/local/soft/redis5/conf/redis.conf [root@localhost redis5]# [root@localhost redis5]# netstat -anp|grep 6379 tcp 0 0 192.168.81.129:6379 0.0.0.0:* LISTEN 14993/./bin/redis-s [root@localhost redis5]# [root@localhost redis5]# [root@localhost redis5]# ps -ef|grep redis root 14993 1 0 07:29 ? 00:00:00 ./bin/redis-server 192.168.81.129:6379 root 15000 2363 0 07:30 pts/0 00:00:00 grep --color=auto redis [root@localhost redis5]# [root@localhost redis5]#
客户端连接测试：
[root@localhost redis5]# ./bin/redis-cli -h 192.168.81.129 -a 123456 Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe. 192.168.81.129:6379> 192.168.81.129:6379> ping PONG 192.168.81.129:6379> 192.168.81.129:6379>
防火墙状态查看：（关于防火墙详细可看linux防火墙——redis connect refused...问题解决）
[root@localhost xgcd]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled) Active: active (running) since Sat 2020-03-21 04:12:17 CST; 2h 59min ago Docs: man:firewalld(1) Main PID: 944 (firewalld) Tasks: 2 (limit: 4874) Memory: 2.6M CGroup: /system.slice/firewalld.service └─944 /usr/libexec/platform-python -s /usr/sbin/firewalld --nofork --nopid Mar 21 04:12:16 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon... Mar 21 04:12:17 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon. [root@localhost xgcd]#
防火墙配置文件查看：
[root@localhost sysconfig]# vi iptables
[root@localhost sysconfig]#
内容为：
# sample configuration for iptables service # you can edit this manually or use system-config-firewall # please do not ask us to add additional ports/services to this default configuration *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT
重启防火墙：
[root@localhost sysconfig]# service iptables restart Redirecting to /bin/systemctl restart iptables.service [root@localhost sysconfig]# systemctl restart iptables.service [root@localhost sysconfig]# [root@localhost sysconfig]# [root@localhost sysconfig]# [root@localhost sysconfig]# iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:6379 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) target prot opt source destination REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@localhost sysconfig]# [root@localhost sysconfig]#
再次查看端口状态：
[root@localhost sysconfig]# iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:6379 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) target prot opt source destination REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) target prot opt source destination [root@localhost sysconfig]#
redis manager 客户端连接测试：
启动
[root@localhost redis5]# ./bin/redis-server /usr/local/soft/redis5/conf/redis.conf
[root@localhost redis5]#
停止
直接杀进程欧了
设置开机自启动
centos8 设置 redis 开机自启动
以下为转载正文
一，下载：
1，下载页面:
2,下载
[root@localhost source]# wget http://download.redis.io/releases/redis-5.0.7.tar.gz
说明：架构森林是一个专注架构的博客，地址：https://www.cnblogs.com/architectforest
对应的源码可以访问这里获取： https://github.com/liuhongdi/
说明：作者:刘宏缔 邮箱: 371125307@qq.com
二，解压：
[root@localhost source]# tar -xzvf redis-5.0.7.tar.gz
三，准备编译
1, 请在操作前确认gcc是否已安装，
如未安装，可以执行这个命令安装：
[root@localhost redis-5.0.7]# yum install gcc
2,请在操作前确认tcl是否已安装
如未安装，可以执行这个命令安装：
[root@localhost redis-5.0.7]# yum install tcl
四，编译：
[root@localhost source]# cd redis-5.0.7/ [root@localhost redis-5.0.7]# make MALLOC=libc
说明：make 后加 MALLOC的参数的原因：
避免提示找不到 jemalloc/jemalloc.h
五，测试编译：
[root@localhost redis-5.0.7]# make test
如果看到以下字样：表示无错误:
o/ All tests passed without errors!
六，安装：
[root@localhost redis-5.0.7]# mkdir /usr/local/soft/redis5 [root@localhost redis-5.0.7]# cd /usr/local/soft/redis5/ [root@localhost redis5]# mkdir bin [root@localhost redis5]# mkdir conf [root@localhost redis5]# cd bin/ [root@localhost bin]# cp /usr/local/source/redis-5.0.7/src/redis-cli ./ [root@localhost bin]# cp /usr/local/source/redis-5.0.7/src/redis-server ./ [root@localhost bin]# cd ../conf/ [root@localhost conf]# cp /usr/local/source/redis-5.0.7/redis.conf ./
七，配置:
[root@localhost conf]# vi redis.conf
设置以下两个地方:
# daemonize no daemonize yes # maxmemory <bytes> maxmemory 128MB
说明：分别是以daemon方式独立运行 / 内存的最大使用限制
八，运行：
[root@localhost conf]# /usr/local/soft/redis5/bin/redis-server /usr/local/soft/redis5/conf/redis.conf
九，检查端口是否在使用中
[root@localhost conf]# netstat -anp | grep 6379 tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN 16073/redis-server
十，查看redis的当前版本:
[root@localhost conf]# /usr/local/soft/redis5/bin/redis-server -v Redis server v=5.0.7 sha=00000000:0 malloc=libc bits=64 build=8e31d2ed9a4c9593
十一,使redis可以用systemd方式启动和管理
1,编辑service文件
[root@localhost liuhongdi]# vim /lib/systemd/system/redis.service
2,service文件内容:
[Unit]
Description=Redis
After=network.target
[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/soft/redis5/bin/redis-server /usr/local/soft/redis5/conf/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
3.重载系统服务
[root@localhost liuhongdi]# systemctl daemon-reload
4,用来管理redis
启动 systemctl start redis 查看状态 systemctl status redis 使开机启动 systemctl enable redis
十二，查看本地centos的版本:
[root@localhost lib]# cat /etc/redhat-release CentOS Linux release 8.1.1911 (Core)
