第二节单机版本redis部署

本文主要是介绍第二节单机版本redis部署，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 部署环境

操作系统：centos7.X
CPU: 2H
内存：4G
IP： 192.168.100.102
部署版本： redis-7.0.15.tar.gz
基础环境： gcc下载

2. 上传Redis安装包

[root@localhost opt]# ll
总用量 2932
drwxrwxr-x. 8 root root    4096 1月   9 19:51 redis-7.0.15
-rw-r--r--. 1 root root 2994329 6月  14 00:15 redis-7.0.15.tar.gz
[root@localhost opt]#

3. 编译

make

    INSTALL redis-sentinelCC redis-cli.oCC redisassert.oCC cli_common.oLINK redis-cliCC redis-benchmark.oLINK redis-benchmarkINSTALL redis-check-rdbINSTALL redis-check-aofHint: It's a good idea to run 'make test' ;)make[1]: 离开目录“/opt/redis-7.0.15/src”

4. 安装

如果编译成功，在src目录中发现几个 Redis 二进制文件，包括：
redis-server：Redis 服务
redis-cli是与 Redis 通信的命令行界面使用程序。

make install

[root@localhost redis-7.0.15]# make install
cd src && make install
which: no python3 in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
make[1]: 进入目录“/opt/redis-7.0.15/src”CC Makefile.dep
make[1]: 离开目录“/opt/redis-7.0.15/src”
which: no python3 in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
make[1]: 进入目录“/opt/redis-7.0.15/src”Hint: It's a good idea to run 'make test' ;)INSTALL redis-serverINSTALL redis-benchmarkINSTALL redis-cli
make[1]: 离开目录“/opt/redis-7.0.15/src”

4. 内核参数设置

4.1 vm.overcommit_memory

Redis建议把这个值设置为1，是为了让fork操作能够在低内存下也执行成功。默认是0
在/etc/sysctl.conf配置文件中修改，修改完成后sysctl -p永久生效

vm.overcommit_memory = 1

4.2 net.core.somaxconn

/etc/sysctl.conf配置文件中修改添加以下内容，修改完成后sysctl -p永久生效

net.ipv4.tcp_max_syn_backlog = 1024
net.core.somaxconn = 1024

5. 启动

进入src目录下

./redis-server ../redis.conf

[root@localhost src]# ./redis-server ../redis.conf
