Linux 环境安装

1、rz/sz：command not  found
　　yum -y install lrzsz 

　nc：yum -y install nc 

　更换yum源：https://www.cnblogs.com/zero-gg/p/8477809.html、https://www.cnblogs.com/hzdwwzz/p/9623942.html

　手动安装rpm：rpm -ivh xinetd-2.3.14-34.el6.x86_64.rpm

　手动安装gcc：先查看内核版本，再到http://vault.centos.org/7.4.1708/os/x86_64/Packages/下下载具体rpm包

cat /etc/redhat-release 
CentOS Linux release 7.4.1708 (Core)

   centos7防火墙查询：firewall-cmd --state。

　挂载硬盘：https://www.cnblogs.com/cqwo/p/7920730.html?tdsourcetag=s_pctim_aiomsg

1. fdisk -l 查看硬盘情况
2. mkfs.ext3 /dev/vdb 格式化硬盘
3. 新建文件夹或者挂载到已有文件夹，mount /dev/vdb /newroot/
4. 修改fstab，以便系统启动时自动挂载磁盘，编辑fstab默认启动文件命令： vi /etc/fstab 回车在其中添加一行： /dev/vdb /wwwroot ext3 defaults 0 0，添加这一行
5. sync将缓存写入服务器，init 6重启服务器

2、安装JDK

1. 使用java -version /ps -ef | grep java / whereis java 等命令确认是否有安装JDK
2. 目前在官网下载低于jdk1.8的java jdk的时候需要登陆，这边分享一个账号，方便下载。账号：2696671285@qq.com 密码：Oracle123
3. 或者Linux下载：wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u221-linux-x64.tar.gz"
4. 新建/usr/local/lib/java，再使用tar -zxvf jdk-8u221-linux-x64.tar.gz -C /usr/local/lib/java/解压
5. vim /etc/profile，文件最后添加，后执行source /etc/profile

export JAVA_HOME=/usr/local/lib/java/jdk1.8.0_221  
export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
export PATH=${JAVA_HOME}/bin:$PATH

 3、安装TOMCAT

　　解压到/usr/local/lib/tomcat下，启动命令./startup.sh。出现Neither the JAVA_HOME nor the JRE_HOME environment variable is defined At least one of these environment variable is needed to run this program。

在setclasspath.sh头部添加配置。

export JAVA_HOME=/usr/local/lib/java/jdk1.8.0_221
export JRE_HOME=${JAVA_HOME}/jre

 4、安装MEMCACHED

1. centos系统自动安装，yum install memcached
2. 启动命令：./memcached -d -m 256 -u root -p 11211 -c 1024 -P /opt/memcached/memcached.pid

3. -d 选项是启动一个守护进程。
   -u root 表示启动memcached的用户为root。
   -m 是分配给Memcache使用的内存数量，单位是MB，默认64MB。
   -M return error on memory exhausted (rather than removing items)。
   -u 是运行Memcache的用户，如果当前为root 的话，需要使用此参数指定用户。
   -p 是设置Memcache的TCP监听的端口，最好是1024以上的端口。
   -c 选项是最大运行的并发连接数，默认是1024。
   -P 是设置保存Memcache的pid文件。

　　3.编写shell脚本，启动命令：cd /usr/bin/，mem_start.sh

#!/bin/sh

./memcached -d -m 256 -u root -p 11211 -c 1024 -P /opt/memcached/memcached.pid

 5、安装ZOOKEEPER

1. 解压到/usr/local/lib/zookeeper-3.4.10
2. 复制zoo_sample.cfg，改名为zoo.cfg
3. 修改zoo.cfg文件，添加

   dataDir=/usr/local/lib/zookeeper-3.4.10  
   dataLogDir=/opt/zklog

   4. 修改源文件，vim /etc/profile，添加配置后刷新 source /etc/profile

export ZOOKEEPER_HOME=/usr/local/lib/zookeeper-3.4.10
export PATH=$PATH:$ZOOKEEPER_HOME/bin

　　5../zkServer.sh start启动

 6、安装kafka

　　解压到/usr/local/lib/kafka_2.11-2.2.0，进入config，修改serve.properties

############################# Server Basics #############################

# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0

############################# Socket Server Settings #############################

# The address the socket server listens on. It will get the value returned from 
# java.net.InetAddress.getCanonicalHostName() if not configured.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://:9092

# Hostname and port the broker will advertise to producers and consumers. If not set, 
# it uses the value for "listeners" if configured.  Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
advertised.listeners=PLAINTEXT://172.18.105.142:9092

# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
#listener.security.protocol.map=PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL

# The number of threads that the server uses for receiving requests from the network and sending responses to the network
num.network.threads=3

# The number of threads that the server uses for processing requests, which may include disk I/O
num.io.threads=8

# The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer.bytes=102400

# The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer.bytes=102400

# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600


############################# Log Basics #############################

# A comma separated list of directories under which to store log files
log.dirs=/opt/kafkalog

# The default number of log partitions per topic. More partitions allow greater
# parallelism for consumption, but this will also result in more files across
# the brokers.
num.partitions=1

# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
# This value is recommended to be increased for installations with data dirs located in RAID array.
num.recovery.threads.per.data.dir=1

############################# Internal Topic Settings  #############################
# The replication factor for the group metadata internal topics "__consumer_offsets" and "__transaction_state"
# For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3.
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1

############################# Log Flush Policy #############################

# Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
#    1. Durability: Unflushed data may be lost if you are not using replication.
#    2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
#    3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.

# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages=10000

# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000

############################# Log Retention Policy #############################

# The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.

# The minimum age of a log file to be eligible for deletion due to age
log.retention.hours=168

# A size-based retention policy for logs. Segments are pruned from the log unless the remaining
# segments drop below log.retention.bytes. Functions independently of log.retention.hours.
#log.retention.bytes=1073741824

# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824

# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000

############################# Zookeeper #############################

# Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
zookeeper.connect=172.18.105.142:2181

# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=6000


############################# Group Coordinator Settings #############################

# The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms=0

 kafka操作

# 后台启动 Kafka bin/kafka-server-start.sh config/server.properties &
启动后输入命令：jps
 
创建topic：bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test01
   报错提示：Error while executing topic command : Replication factor: 2 larger than available brokers: 0
查询列表：bin/kafka-topics.sh -list -zookeeper localhost:2181
启动producer：bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test01
启动consumer：bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test01 --from-beginning 

 

原因:没有在kafka目录下创建zookeeper ，指定myid
解决：
cd kafka_2.11-1.1.0
　　mkdir zookeeper
　　cd zookeeper 
　　touch myid 
　　echo 0 > myid 
重新启动kafka就ok

 7、安装Redis

 8、安装MONGODB

　　Windows版：注册服务

D:UCAPmongodbinmongod.exe --port 27017 --logpath D:UCAPmongodblogsmongodb.log --dbpath D:UCAPmongodbdata --directoryperdb --config "D:UCAPmongodbmongod.cfg" --install --serviceName "MongoDB"

 9、安装mysql
