3. 安装 ZooKeeper

# cd /opt
# wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
# tar zxfv zookeeper-3.4.9.tar.gz
# mkdir -p /usr/local/zookeeper
# mv zookeeper-3.4.9 /usr/local/zookeeper/3.4.9
# cd /usr/local/zookeeper/3.4.9/conf
# cp zoo_sample.cfg zoo.cfg
# vim zoo.cfg 修改其内容
dataDir=/data/zookeeper/3.4.9/data
dataLogDir=/data/zookeeper/3.4.9/logs
创建 data和logs目录
# mkdir -p /data/zookeeper/3.4.9/data
# mkdir -p /data/zookeeper/3.4.9/logs

注意：3.5.x 依赖 Java 9

配置 systemd

# vim /usr/lib/systemd/system/zookeeper.service

[Unit]
Description=zookeeper.service
After=network.target

[Service]
Type=forking
Environment=JAVA_HOME=/usr/local/java/1.8.0_202
Environment=ZOO_LOG_DIR=/data/zookeeper/3.4.9/logs
Environment=ZOO_LOG4J_PROP=INFO,CONSOLE
ExecStart=/usr/local/zookeeper/3.4.9/bin/zkServer.sh start
ExecStop=/usr/local/zookeeper/3.4.9/bin/zkServer.sh stop
ExecReload=/usr/local/zookeeper/3.4.9/bin/zkServer.sh restart

[Install]
WantedBy=multi-user.target

注意: Environment=JAVA_HOME=jdk-install-dir

启动服务器

# systemctl daemon-reload
# systemctl start zookeeper
# systemctl enable zookeeper

4. 安装 Redis

# cd /opt

一、安装gcc依赖

由于 redis 是用 C 语言开发，安装之前必先确认是否安装 gcc 环境（gcc -v），如果没有安装，执行以下命令进行安装
# yum install -y gcc 

二、下载并解压安装包
# wget http://download.redis.io/releases/redis-5.0.9.tar.gz
# tar -zxvf redis-5.0.9.tar.gz

三、cd切换到redis解压目录下，执行编译
# cd redis-5.0.9
# make

四、安装并指定安装目录
# make install PREFIX=/usr/local/redis

五、启动服务
5.1前台启动
# cd /usr/local/redis/bin/
# ./redis-server

5.2后台启动

从 redis 的源码目录中复制 redis.conf 到 redis 的安装目录
# cp /opt/redis-5.0.9/redis.conf /usr/local/redis/bin/

修改 redis.conf 文件，把 daemonize no 改为 daemonize yes
# vi redis.conf

后台启动
# ./redis-server redis.conf

六、设置开机启动
添加开机启动服务
# vi /etc/systemd/system/redis.service

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

[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/bin/redis.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

注意：ExecStart配置成自己的路径

设置开机启动
# systemctl daemon-reload
# systemctl start redis.service
# systemctl enable redis.service

创建 redis 命令软链接
# ln -s /usr/local/redis/bin/redis-cli /usr/bin/redis

增加密码：

在配置文件中有个参数： requirepass  这个就是配置redis访问密码的参数；

将前面的注释去掉，后面增加内容

比如 requirepass test123

解决redis远程连接不上的问题

redis现在的版本开启redis-server后，redis-cli只能访问到127.0.0.1，因为在配置文件中固定了ip，因此需要修改redis.conf（有的版本不是这个文件名，只要找到相对应的conf后缀的文件即可）文件以下几个地方。

1.bind 127.0.0.1改为 #bind 127.0.0.1 (注释掉)

2.protected-mode yes 改为 protected-mode no

3.加入 daemonize no(这个是是否在后台启动不占用一个主程窗口)

5. 安装 kafka

# cd /opt
# wget https://archive.apache.org/dist/kafka/2.5.1/kafka_2.12-2.5.1.tgz
# tar zxfv kafka_2.12-2.5.1.tgz
# mv kafka_2.12-2.5.1 /usr/local/kafka
# cd /usr/local/kafka
修改配置文件
# vim /usr/local/kafka/config/server.properties
修改
log.dirs=/usr/local/kafka/logs
advertised.listeners=PLAINTEXT://127.0.0.1:9092
创建日志目录
# mkdir /usr/local/kafka/logs
配置开机自启
# vim /usr/lib/systemd/system/kafka.service

[Unit]
Description=kafka server daemon
After=kafka.target
[Service]
Type=forking
Environment=JAVA_HOME=/usr/local/java/1.8.0_202
ExecStart=/usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties
ExecStop=/usr/local/kafka/bin/kafka-server-stop.sh /usr/local/kafka/config/server.properties
Restart=always
[Install]
WantedBy=multi-user.target

# systemctl daemon-reload
# systemctl start kafka
# systemctl enable kafka
