基础组件部署安装步骤：
(一) 安装python3
Yum –y install wget*
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
mv Python-3.6.3.tgz /usr/local/src/
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
cd /usr/local/src/
tar -zxvf Python-3.6.1.tgz
cd Python-3.6.1
./configure --prefix=/usr/local/python3.6.3
出现以下标志信息：
[图片上传失败...(image-75911b-1640071734791)]
make && make install 出现以下标示：
[图片上传失败...(image-3c73c7-1640071734791)]
cp -r /usr/local/python3.6/ /usr/bin/
mv /usr/bin/python /usr/bin/pythonbak
ln -s /usr/local/python3.6.3/bin/python3.6 /usr/bin/python3
加入环境变量：
临时：export PATH=/usr/local/python3.6.1/bin:$PATH
永久性的：vi /etc/profile 在最后加入： export PATH=/usr/local/python3.6/bin:$PATH保存后：source /etc/profile
Env 查看相关的环境变量信息
vi /usr/bin/yum
修改第一行为：#!/usr/bin/python2.7
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5=c607dd118eae682c44ed146367a17e26
tar -zxvf setuptools-19.6.tar.gz
cd setuptools-19.6
python3 setup.py build
python3 setup.py install
wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5=3a73c4188f8dbad6a1e6f6d44d117eeb
tar -zxvf pip-8.0.2.tar.gz
cd pip-8.0.2
python3 setup.py build
python3 setup.py install
ln -s /usr/local/python3.6.3/bin/pip /usr/bin/pip
pip install --upgrade pip
报错：
1.编码问题：
export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN.UTF-8
之后就解决了 装好后，unset export LANG下..

(二)Nginx中间件安装：
安装包：https://nginx.org/en/download.html
wget http://nginx.org/download/nginx-1.6.2.tar.gz
yum -y install gcc gcc-c++ autoconf automake zlib zlib-devel openssl openssl-devel pcre pcre-devel
wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpm
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.35
make
make install
/usr/local/webserver/nginx/sbin/nginx –v 查看版本信息
启动 /usr/local/webserver/nginx/sbin/nginx -c /usr/local/webserver/nginx/conf/nginx.conf
启动nginx /usr/local/webserver/nginx/sbin/nginx
关闭 nginx /usr/local/webserver/nginx/sbin/nginx -s stop
重启nginx /usr/local/webserver/nginx/sbin/nginx –s reload
关闭 nginx /usr/local/webserver/nginx/sbin/nginx –s stop
安装源库
chmod +x nginx-release-centos-7-0.el7.ngx.noarch.rpm
rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
yum -y install nginx
访问相关的网址 192.168.10.11：80
(二)mysql数据库安装 10.11直接yum安装了
rpm -qa |grep mysql
rpm -e –nodeps mysql-community-release-el6-5.noarch
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
systemctl status mysqld
systemctl start mysqld
systemctl enable mysqld
mysqld –initalize 进行密码得重置
grep 'temporary password' /var/log/mysqld.log 可以看到临时得密码信息等 V4Q#aYK!0MQz
然后进行登录 mysql –uroot –p
输入密码：
更改密码：ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
set global validate_password_policy=0;
set global validate_password_length=1;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root'; 将密码修改为root
grant all privileges on . to 'root'@'%' identified by 'root' with grant option;
systemctl restart mysqld 重启相关得mysql服务
(三)redis安装
wget http://download.redis.io/releases/redis-3.0.0.tar.gz
tar zxvf redis-3.0.0.tar.gz
cd redis-3.0.0
make
make test
mkdir -p /etc/redis
cp redis.conf /etc/redis/6379.conf
将启动文件拷贝到init.d中， Cp utils/redis_init_script /etc/init.d/redisd
修改启动脚本参数 , vi /etc/init.d/redisd
添加已下代码
chkconfig: 2345 10 90
description: Start and Stop redisd
修改
EXEC= /root/redis-3.0.0/src/redis-server
CLIEXEC= /root/redis-3.0.0/src/redis-cli
PIDFILE=/etc/redis/redis_${REDISPORT}.pid
启动方式
service redisd start 开启来redis-server
/root/redis-3.0.0/src/redis-server /etc/redis/redis.conf 开启
whereis redis 找到redis得具体路径信息
开启redis-cli
/root/redis-3.0.0/src/redis-cli
redis-cli -p 6379 -a redis 使用密码登录
redis-cli -h 127.0.0.1 -p 6379 -a "redis" 远程登录
修改密码
1-需要重启服务，找到redis.conf 修改requirepass这个配置文件，取消注释后面设置成需要得密码
2-连接redis后，config set requirepass redis ,则密码就设置成立redis, config get requirepass 可以看到密码，需要输入 auth redis 然后输入ping，显示PONG就可以了
(四) rabbitmq安装
RabbitMQ是实现了高级消息队列协议（AMQP）
RabbitMQ之前, 需要先安装Erlang ，rabbitmq需要socat依赖,
yum install xmlto gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC-devel wxBase wxGTK wxGTK-gl perl –y
下载erlang
安装Erlang依赖yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto
rpm -ivh erlang-23.2.7-1.el7.x86_64.rpm
测试是否正常
输入命令：erl 看到相关得命令则说明正常
Erlang/OTP 23 [erts-11.1.8] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [hipe]
Eshell V11.1.8 (abort with ^G)
1>
输入halt(). 则退出命令行就可以了
安装rabbitMQ
yum install -y socat
rpm -ivh rabbitmq-server-3.9.3-1.el8.noarch.rpm
rabbitmq-server start ----------------------(前台启动，ctrl+c进程就挂了)
rabbitmq-server -detached ----------------------(后台启动)
ps -ef | grep rabbitmq ----------------------(查看rabbitmq进程)
rabbitmqctl stop 关闭rabbitmq进程
启动web管理界面(没有启动浏览器是访问不了的 rabbitmq-plugins enable rabbitmq_management
关闭管控台: rabbitmq-plugins disable rabbitmq_management
systemctl stop firewalld 关闭防火墙
systemctl disable firewalld
开启web管理插件
rabbitmq-plugins enable rabbitmq_management
启动服务
systemctl start rabbitmq-server.service
添加rabbitMQ用户跟权限
./rabbitmqctl add_user admin guest -----------------------（添加用户，用户名admin，密码admin）
./rabbitmqctl set_permissions -p / admin "." "," ".*" -----------------------（给admin用户设置访问权限）
./rabbitmqctl set_user_tags admin administrator -----------------------（给admin设置为管理员）
rabbitmqctl delete_user guest
启动：systemctl start rabbitmq-server.service
启动控制台：rabbitmq-plugins enable rabbitmq_management
WEB访问：http://192.168.1.11:15672/ 账号：admin 密码：guest
