预置步骤安装gcc工具# 安装gccyuminstallgcc-c# 安装PCRE pcre-develyuminstall-ypcre pcre-devel# 安装zlibyuminstall-yzlib zlib-devel# 安装Open SSLyuminstall-yopenssl openssl-devel安装JDK下载jdk rpm并安装# 下载https://www.oracle.com/java/technologies/downloads/#java8# 安装rpm-ivhjdk-8u401-linux-x64.rpm# 或yuminstalljdk-8u401-linux-x64.rpm配置JAVA_HOME# 查看java的安装路径readlink -f $(which java)exportJAVA_HOMEjava的安装目录(配置到bin的父目录即可)exportPATH$JAVA_HOME/bin:$PATH安装MySQL检测是否有残留的mariadb# centos7会默认安装mariadb会影响mysql安装需要将其删除。rpm-aq|grepmariadb# 有的话将其删除rpm-e--nodepsmariadb_package下载MySQL 8.0.26的rpm包# 此处建议下载完整的rpm bundle包不然安装时可能会因缺少依赖而报错https://downloads.mysql.com/archives/community/解压并安装下载好的mysql rpm源tar-xvfmysql-8.0.26-1.el7.x86_64.rpm-bundle.tar yum localinstall

的配置文件位于源码的redis.conf。将这个配置文件复制到合适的目录例如/etc/redis/mkdir/etc/rediscpredis.conf /etc/redis/redis.conf配置redis后台启动vim/etc/redis.conf# 搜索daemonize将daemonize no改为daemonize yesdaemonizeyes# 搜索notify-keyspace-events将其配置为notify-keyspace-events Exnotify-keyspace-events Ex# 配置远程可以访问使其可以通过客户端工具连接# 1、注释掉bind 127.0.0.1# 2、关闭保护模式protected-mode no启动 Redis 服务并设置开机自启:重新加载Systemd 管理器配置systemctl daemon-reload查看Redis服务状态systemctl status redis.service设置 Redis 服务开机自启systemctlenableredis.service验证 Redis 是否在运行:检查 Redis 服务的状态systemctl status redis.service尝试通过redis客户端连接到redis服务redis-cliping# 返回pong 则说明服务正常返回/opt目录删除redis压缩文件和解压后的文件rm-rfredis-*安装Kafka下载解压kafka压缩包# 下载https://kafka.apache.org/downloads# 解压tar-zxvfkafka_2.12-3.2.0.tgz-C/usr/local/kafka创建软链接ln-s/usr/local/kafka/kafka_2.12-3.2.0
