第二节 单机版本redis部署

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-sentinel
    CC redis-cli.o
    CC redisassert.o
    CC cli_common.o
    LINK redis-cli
    CC redis-benchmark.o
    LINK redis-benchmark
    INSTALL redis-check-rdb
    INSTALL redis-check-aof

Hint: 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-server
    INSTALL redis-benchmark
    INSTALL 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
