Cent0S7 安装Redis

1.安装前环境检查

1.1 查看redis的安装环境

redis是由C语言开发，因此安装之前必须要确保服务器已经安装了gcc，可以通过如下命令查看机器是否安装：

gcc -v

如果没有安装则通过以下命令安装：

yum install -y gcc

2.redis安装

2.1 创建Redis文件夹

sudo mkdir /volume1/Reids

2.2 下载Redis包到对应目录下

wget -P /volume1/ https://download.redis.io/releases/redis-6.2.8.tar.gz

2.3 解压下载下来的Redis包

tar -zxvf redis-6.2.8.tar.gz

2.4 进入解压目录

cd /volume1/redis-6.2.8

2.5编译Redis

make

2.6 前面创建了Redis目录，现在指定安装路径目录并进行安装

make install PREFIX=/volume1/redis

2.7 进入redis对应目录进行服务启动

cd /volume1/redis/bin

2.8 启动redis服务

./redis-server

3 配置Redis

3.1 从 redis 的源码目录中复制 redis.conf 到 redis 的安装目录

cp /volume1/redis-6.2.8/redis.conf /volume1/redis/bin/

3.2 进入对应目录，修改redis.conf配置文件

#进入reids目录
cd /volume1/redis/bin/#配置redis的配置文件
vi redis.conf

修改内容如下：

daemonize 的值从 no 修改成 yes
将redis指定链接ip改成不限ip链接，将127.0.0.1改成0.0.0.0

daemonize 的值从 no 修改成 yes

# 在 这个下面
################################# GENERAL ###################################### 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 no

将redis指定链接ip改成不限ip链接，将127.0.0.1改成0.0.0.0 |将 bind 127.0.0.1 -::1 改成 bind 0.0.0.0 -::1

# 在 这个下面
############################### NETWORK ###################################
# are already in use will always fail, and unsupported protocols will always BE
# silently skipped.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1     # listens on two specific IPv4 addresses
# bind 127.0.0.1 ::1              # listens on loopback IPv4 and IPv6
# bind * -::*                     # like the default, all available interfaces
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only on the
# IPv4 and IPv6 (if available) loopback interface addresses (this means Redis
# will only be able to accept client connections from the same host that it is
# running on).
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT OUT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
bind 127.0.0.1 -::1

3.4 启动服务

./redis-server redis.conf

3.5 检查redis是否启动成功

ps -ef |grep redis

4.设置开机启动

4.1 进入到/lib/systemd/system/目录，创建redis.service文件

cd /lib/systemd/system/

4.2 创建redis.service文件

vim redis.service

4.3 编写文件内容

[Unit]
Description=redis-server
After=network.target[Service]
Type=forking
# ExecStart需要按照实际情况修改成自己的地址
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true[Install]
WantedBy=multi-user.target

\\【例如我的配置：】

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
// ExecStart需要按照实际情况修改成自己的地址
ExecStart=/volume1/redis/bin/redis-server /volume1/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

:wq! 保持并推出文件

4.4 使用Redis服务新命令

# 开机自动启动
systemctl enable redis.service# 启动redis服务
systemctl start redis.service# 查看服务状态
systemctl status redis.service# 停止服务
systemctl stop redis.service# 取消开机自动启动(卸载服务)
systemctl disabled redis.service
