Linux下安装Redis的实现过程及报错解决方法

今天安装redis出现些之前安装不曾出现错误，一并在此做个记录

一、安装redis及出现错误

首先下载redis，官方下载地址页面：https://redis.io/download

我们这里选择稳定版6.0.1版本

正常安装步骤如下：

[root@localhost ~]# yum install gcc
[root@localhost ~]# cd /usr/local
[root@localhost local]# wget http://download.redis.io/releases/redis-6.0.1.tar.gz
[root@localhost local]# tar -xvf redis-6.0.1.tar.gz
[root@localhost local]# cd /usr/local/redis-6.0.1/
[root@localhost redis-6.0.1]# make PREFIX=/usr/local/redis install

这里报了如下错误

make[1]: *** [server.o] 错误 1
make[1]: 离开目录“/usr/redis-6.0.1/src”
make: *** [all] 错误 2

^

serverLog(LL_WARNING,”WARNING: The TCP backlog setting of %d cannot be enforced because /proc/sys/net /core/somaxconn is set to the lower value of %d.”, server.tcp_backlog, somaxconn);

解决办法：升级gcc版本

[root@localhost redis-6.0.1]# gcc -v # 查看gcc版本
[root@localhost redis-6.0.1]# yum -y install centos-release-scl # 升级到9.1版本
[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
以上为临时启用，如果要长期使用gcc 9.1的话：
[root@localhost redis-6.0.1]# echo “source /opt/rh/devtoolset-9/enable” >>/etc/profile

再执行编译：

[root@mmjredis redis-6.0.1]# make PREFIX=/usr/local/redis install

安装成功会出现：Hint: It’s a good idea to run ‘make test’ 😉

我们执行一下make test来进行测试一下

出现了如下错误:

[root@localhost redis-6.0.1]# make test
cd src && make test
make[1]: 进入目录“/usr/redis-6.0.1/src”
CC Makefile.dep
make[1]: 离开目录“/usr/redis-6.0.1/src”
make[1]: 进入目录“/usr/redis-6.0.1/src”
You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [test] 错误 1
make[1]: 离开目录“/usr/redis-6.0.1/src”
make: *** [test] 错误 2

解决办法：

[root@localhost redis-6.0.1]# yum install tcl[root@localhost redis-6.0.1]# make test

测试成功如下：

先运行redis试一下：

[root@localhost redis-6.0.1]# /usr/local/redis-6.0.1/src/redis-server /usr/local/redis-6.0.1/redis.conf
32101:C 13 May 2020 17:01:48.248 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

       `-.__.-'

二、后台启动

简单修改后台启动

[root@localhost redis-6.0.1]# vim redis.conf

daemonize no 改成 daemonize yes

再来运行一下

[root@localhost redis-6.0.1]# /usr/redis-6.0.1/src/redis-server /usr/redis-6.0.1/redis.conf
30385:C 13 May 2020 16:57:58.918 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
30385:C 13 May 2020 16:57:58.918 # Redis version=6.0.1, bits=64, commit=00000000, modified=0, pid=30385, just started
30385:C 13 May 2020 16:57:58.918 # Configuration loaded

后台运行成功，我们查看一下，并终止程序

[root@localhost redis-6.0.1]# ps -aux|grep redis| grep -v grep
root 29836 0.0 0.0 162416 7912 ? Ssl 16:56 0:00 /usr/redis-6.0.1/src/redis-server 127.0.0.1:6379
[root@localhost redis-6.0.1]# kill -9 29836

我们这里用到的是用后台systemctl启动redis

首先把redis加入service服务

vim /lib/systemd/system/redis.service

写入

[Unit]
Description=redis
After=network.target

[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/redis-6.0.1/src/redis-server /usr/local/redis-6.0.1/etc/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

注意路径问题，以及PIDFile的路径对应的是redis-6.0.1/src/redis-server里面的PIDFile

wq保存退出即可

接着运行以下

[root@localhost redis-6.0.1]# systemctl enable redis.service # 加入开机启动

[root@localhost redis-6.0.1]# systemctl is-enabled redis.service # 查看开机是否启动成功
enabled

[root@localhost redis-6.0.1]# systemctl start redis #开启redis服务

[root@localhost redis-6.0.1]# systemctl status redis //查看redis运行状态

如果启动出现问题，可以通过systemctl status redis来查看日志修复

如图已经启动成功
