关于redis:Linux环境下安装redis

下载 redis 安装包, 放到 root 目录外面下载地址
在 /usr/local/ 下创立 redis ⽂件夹并进⼊
```
cd /usr/local/
mkdir redis
cd redis
```
将 redis 安装包解压到 /usr/local/redis
```
tar -zxvf /root/redis-6.2.5.tar.gz -C ./
```
解压完之后，/usr/local/redis ⽬录中会呈现⼀个 redis-6.2.5 的⽬录

编译并装置
```
cd redis-6.2.5
make && make install
```

进⼊ utils ⽬录，并执⾏上面命令

cd utils/
./install_server.sh

这步可能会报错

Welcome to the redis service installer
This script will help you easily set up a running redis server

This systems seems to use systemd.
Please take a look at the provided example service unit files in this directory, and adapt and install them. Sorry!

正文上面的代码 vim install_server.sh

76 行
#bail if this system is managed by systemd
#_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
#unset _pid_1_exe

查看 redis 服务启动状况

systemctl status redis_6379.service

看状态是不是 Active: active (running) , 如果状态是 Active: active (exited)

● redis_6379.service - LSB: start and stop redis_6379
Loaded: loaded (/etc/rc.d/init.d/redis_6379; bad; vendor preset: disabled)

Active: active (exited) 状态删除 pid 文件

cd /var/run
rm redis_6379.pid

Active: active (exited) 状态删除 dump.rdb（内存快照）文件

 cd /var/lib/redis/6379
 mv dump.rdb dump.rdb_bak

Active: active (exited) 状态

ps -ef |grep redis
kill -9 过程 id(如果有)
systemctl start redis

设置容许近程连贯, 编辑 redis 配置⽂件
```
vim /etc/redis/6379.conf
```
将 bind 127.0.0.1 批改为 0.0.0.0
```
bind 0.0.0.0
systemctl restart redis_6379.service
```
设置拜访明码
```
vim /etc/redis/6379.conf
```
找到 #requirepass foobared 去掉正文，批改 foobared 为⾃⼰想要的明码，保留即可。
```
requirepass admin
```
保留，重启 Redis 服务即可
```
systemctl restart redis_6379.service
```

关于redis:Linux环境下安装redis

一、筹备工作

二、编译装置

三、将 redis 服务装置零碎服务并后盾启动
