实用软件：putty&WinScp
1.安装JDK 文件为：jdk-8u161-linux-x64.rpm
1.第一步就是把文件上传到服务器
2.rpm -ivh jdk-8u161-linux-x64.rpm 安装JDK，一般在安装以后，环境变量已经配置完成
2.安装数据库
1、配置YUM源
1.下载mysql源安装包 wgethttp://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
2. 安装mysql源shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm
3.检查mysql源是否安装成 yum repolist enabled| grep "mysql.*-community.*"
2、安装MySQL
yum install mysql-community-server
3、启动MySQL服务
systemctl start mysqld
查看MySQL的启动状态
systemctl status mysqld
4、开机启动
systemctl enable mysqld
systemctl daemon-reload
5、修改root本地登录密码
在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql进行修改：
grep'temporary password'/var/log/mysqld.log
登录：mysql -u root -p
修改密码：set password for 'root'@'localhost'=password('****');
注意：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误，如下图所示：
通过msyql环境变量可以查看密码策略的相关信息：
show variables like'%password%';
6、添加远程登录用户
GRANT ALL PRIVILEGES ON *.* TO 'sjd'@'%' IDENTIFIED BY 'Sjd#199313' WITH GRANT OPTION;
3.安装redis
1.下载redis安装包
wget http://download.redis.io/releases/redis-4.0.6.tar.gz
2：解压压缩包
tar -zxvf redis-4.0.6.tar.gz
3：yum安装gcc依赖
yum install gcc
4：跳转到redis解压目录下
cd redis-4.0.6
5：编译安装
make MALLOC=libc
将/usr/local/redis-4.0.6/src目录下的文件加到/usr/local/bin目录
cd src && make install
6、以后台进程方式启动redis
1修改redis.conf文件将
daemonize no 修改为 daemonize yes
.
4.安装zookeeper,作用为搭建dubbo的时候必须的，文件为：zookeeper-3.4.10.tar.gz
1、创建 /usr/local/services/zookeeper 文件夹：
mkdir -p /usr/local/services/zookeeper
2、进入到 /usr/local/services/zookeeper 目录中：
cd /usr/local/services/zookeeper
3、下载 zookeeper-3.4.9.tar.gz：
wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz
4、解压缩 zookeeper-3.4.9.tar.gz：
tar -zxvf zookeeper-3.4.9.tar.gz
5、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/conf 目录中：
cd zookeeper-3.4.9/conf/
6、复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：
cp zoo_sample.cfg zoo.cfg
7、用 vim 打开 zoo.cfg 文件并修改其内容为如下：
# The number of milliseconds of each tick
# zookeeper 定义的基准时间间隔，单位：毫秒
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# dataDir=/tmp/zookeeper
# 数据文件夹
dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data
# 日志文件夹
dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs
# the port at which the clients will connect
# 客户端访问 zookeeper 的端口号
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
8、保存并关闭 zoo.cfg 文件:
9、进入到 /usr/local/services/zookeeper/zookeeper-3.4.9/bin 目录中：
cd ../bin/
10、用 vim 打开 /etc/ 目录下的配置文件 profile：
vim /etc/profile
并在其尾部追加如下内容：
# idea - zookeeper-3.4.9 config start - 2016-09-08
export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH
11、使 /etc/ 目录下的 profile 文件即可生效：
source /etc/profile
12、启动 zookeeper 服务：
zkServer.sh start
5.neo4j安装
wgethttp://debian.neo4j.org/neotechnology.gpg.key
rpm --import neotechnology.gpg.key
然后创建 /etc/yum.repos.d/neo4j.repo 文件：
cat < /etc/yum.repos.d/neo4j.repo
[neo4j]
name=Neo4j Yum Repo
baseurl=http://yum.neo4j.org/stable
enabled=1
gpgcheck=1
EOF
最后使用yum安装
yum install neo4j
