1.Nginx在Linux下的安装

1.1.ubuntu环境下的安装配置

1.1.1.Nginx的基本安装

#1.Nginx的下载安装
  sudo apt-get update
  apt-get install nginx
#2.Nginx的配置文件路径
  sudo vi /etc/nginx/nginx.conf
#3.Nginx的启动和停止
  sudo service nginx start
  sudo service nginx stop

  ubuntu中安装Nginx相对来说比较简单，默认端口是80，在浏览器中输入ip:80即可访问。

1.1.2.Nginx配置vhost

  所谓vhost说白了就是把多个应用映射到一个ip地址上，达到多对一的效果。

#1.创建nginx虚拟主机配置文件 
  sudo vi /etc/nginx/sites-available/mydefault.vhost 
#mydefault.vhost文件内容如下：
#-----------------------------mydefault.vhost--------------------------------------#
#用户端api接口转发
server {
  listen       80;
  server_name  192.168.0.65;
  index index.html;
  
  location /uc {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6001;
      proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
  }
  location /otc {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6002;
      proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
  }
  location /exchange {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6003;
      proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
  }
  location /market {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6004;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Real-IP $remote_addr;
  }
  location /chat {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6007;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Real-IP $remote_addr;
  }
}
#后台api接口转发
server {
  listen       80;
  server_name  api.admin.domain.com;
  index index.html;
  location / {
    index index.html;
    client_max_body_size    5m;
    proxy_pass http://127.0.0.1:6010;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Real-IP $remote_addr;
  }
}
#---------------------------mydefault.vhost----------------------------------#
#2.建立一个mydefault.vhost文件的链接
#（因为nginx的主配置文件nginx.conf会自动应用sites-enabled中的配置文件，所以我们需要在sites-enabled中建立一个mydefault.vhost文件的链接）
  cd /etc/nginx/sites-enabled
  sudo ln -s /etc/nginx/sites-available/mydefault.vhost mydefault.vhost
#3.重新加载nginx使配置生效 
  sudo /etc/init.d/nginx reload

1.2.centos环境下的安装配置

  centos7系统库中默认是没有nginx的rpm包的，所以我们自己需要先更新下rpm依赖库

#1.使用yum安装nginx需要包括Nginx的库，安装Nginx的库
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
#2.rpm包的安装：
#2.1.安装一个包
  rpm -ivh
#2.2.升级一个包，没安装过的不能使用升级命令
  rpm -Uvh
#2.3.移走一个包
  rpm -e
#3.安装准备依赖lib库
  yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
#4.使用下面命令安装nginx
  yum install nginx
#5.启动/重启/停止Nginx
  service nginx start 或 systemctl start nginx.service
  service nginx restart
  /etc/init.d/nginx stop
  /etc/init.d/nginx start

2.kafka在Linux下的安装

2.1.ubuntu环境下的安装配置

2.1.1.Kafka的基本环境的安装

##Install and Start Apache Kafka Server : 0.0.0.0:9092
#0: update and upgrade
  sudo apt-get update -y
#1: home dir
  cd /home/imex
#2: find new package @ www.apache.org
  http://mirror.bit.edu.cn/apache/kafka/1.0.1/kafka_2.11-1.0.1.tgz
#3: download
  wget http://mirror.bit.edu.cn/apache/kafka/1.0.1/kafka_2.11-1.0.1.tgz
#4: mkdir
  sudo mkdir /opt/Kafka
  cd /opt/Kafka
#5: install
    sudo tar -xvf /home/imex/kafka_2.11-1.0.1.tgz -C /opt/Kafka/
#6: start
  sudo  /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-server-start.sh         
  /opt/Kafka/kafka_2.11-1.0.1/config/server.properties
#7: to start the Kafka server as a background process:
  sudo nohup /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-server-start.sh /opt/Kafka/kafka_2.11-1.0.1/config/server.properties /tmp/kafka.log 2>&1 &
#check 
   netstat -ant | grep :9092
#8: Testing Kafka Server
#-- To test Kafka, create a sample topic with name "testing" in Apache Kafka using the following command:
  sudo /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1  --partitions 1 --topic testing       
#-- Now, ask Zookeeper to list available topics on Apache Kafka by running the following command:
  sudo /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-topics.sh --list --zookeeper localhost:2181    
#--Now, publish a sample messages to Apache Kafka topic called testing by using the following producer command:
  sudo /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic testing
#--Now, use consumer command to check for messages on Apache Kafka Topic called testing by running the following command:
  sudo /opt/Kafka/kafka_2.11-1.0.1/bin/kafka-console-consumer.sh --    zookeeper localhost:2181 --topic testing --from-beginning

2.1.2.Kafka的服务配置

#1.创建服务文件
  cd /etc/systemd/system/
  sudo vi kafka.service
#2.填充内容
[Unit]
Description=Redis In-Memory Data Store
After=network.target

[Service]
Type=forking
ExecStart= /opt/Kafka/kafka_2.12-1.1.0/bin/kafka-server-start.sh /opt/Kafka/kafka_2.12-1.1.0/config/server.properties
ExecStop=/opt/Kafka/kafka_2.12-1.1.0/bin/kafka-server-stop.sh
Restart=alwaiys
PrivateTmp=true

[Install]
WantedBy=multi-user.target
#3.启动、停止命令
  sudo systemctl start kafka.service
  sudo systemctl stop kafka.service

2.1.3.Kafka常见问题解决

1).Kafka自动关闭问题

  Kafka在启动一段时间后，如果出现服务自动关闭情况，可在启动kafka的时使用守护进程模式启动，即在原启动命令中加 -daemon。

kafka-server-start.sh  -daemon  config/server.properties  &

3.mysql在Linux下的安装
