LNMT架构：Linux+Nginx+Mysql+Tomcat
(nginx实现负载均衡动静分离,反向代理)
环境说明：
| IP | 安装的服务 |
|---|---|
| 192.168.209.12 | tomcat |
| 192.168.209.13 | nginx mysql |
********************************nginx安装**************************
说明：nginx安装的方式的是编译安装
1.//创建系统用户nginx
[root@lanzhiyong ~]# useradd -r -M -s /sbin/nologin nginx
//安装依赖环境
[root@lanzhiyong ~]# yum -y install pcre-devel openssl openssl-devel gd-devel
[root@lanzhiyong ~]# yum -y groups mark install 'Development Tools'
//创建日志存放目录
[root@lanzhiyong ~]# mkdir -p /var/log/nginx
[root@lanzhiyong ~]# chown -R nginx.nginx /var/log/nginx
//下载nginx
[root@lanzhiyong ~]# cd /usr/src/ [root@lanzhiyong src]# wgethttp://nginx.org/download/nginx-1.14.0.tar.gz
//编译安装
[root@lanzhiyong src]# tar xf nginx-1.14.0.tar.gz
[root@lanzhiyong src]# cd nginx-1.14.0
[root@lanzhiyong nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-debug --with-http_ssl_module --with-http_realip_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_stub_status_module --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log
[root@lanzhiyong nginx-1.14.0]# make -j $(grep 'processor' /proc/cpuinfo | wc -l) && make install
2.nginx安装后配置
//配置环境变量
[root@lanzhiyong ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/profile.d/nginx.sh
[root@lanzhiyong ~]# source /etc/profile.d/nginx.sh
[root@lanzhiyong ~]# nginx
[root@lanzhiyong ~]# ss -antl

说明：mysql安装的方式是二进制安装
//安装依赖 包
[root@lanzhiyong ~]# yum -y install ncurses-devel openssl-devel openssl cmake mariadb-devel
//创建用户和组
[root@lanzhiyong ~]# cd /usr/src/
[root@lanzhiyong src]# groupadd -r -g 306 mysql
[root@lanzhiyong src]# useradd -M -s /sbin/nologin -g 306 -u 306 mysql
//下载二进制格式的mysql软件包
[root@lanzhiyong src]# wget https://downloads.mysql.com/archives/get/file/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
//解压软件至/usr/local
[root@lanzhiyong src]# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
[root@lanzhiyong src]# cd /usr/local/
//创建软连接
[root@lanzhiyong local]# ln -sv mysql-5.7.22-linux-glibc2.12-x86_64/ mysql
//修改目录/usr/local/mysql的属主属组
[root@lanzhiyong local]# chown -R mysql.mysql /usr/local/mysql
[root@lanzhiyong local]# ll /usr/local/mysql
//添加环境变量
[root@lanzhiyong ~]# ls /usr/local/mysql
[root@lanzhiyong ~]# echo 'export PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh
[root@lanzhiyong ~]# source /etc/profile.d/mysql.sh
[root@lanzhiyong ~]# echo $PATH
//建立数据存放目录
[root@lanzhiyong ~]# mkdir /opt/data
[root@lanzhiyong ~]# chown -R mysql.mysql /opt/data/
[root@lanzhiyong ~]# ll /opt/

//初始化数据库 注意这个命令后会生成临时密码 要记住 jd?ajfrKY4pQ
[root@lanzhiyong ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/opt/data/
//配置mysql
//软连接
[root@lanzhiyong ~]# ln -sv /usr/local/mysql/include/ /usr/local/include/mysql

说明：下载好tomcat解压就能配置了
//java环境安装，安装jdk环境
[root@lanzhiyong ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel
[root@lanzhiyong ~]# java -version
//下载tomcat
[root@lanzhiyong ~]# cd /usr/src/

[root@lanzhiyong src]# tar xf apache-tomcat-9.0.8.tar.gz -C /usr/local/
[root@lanzhiyong local]# tar xf apache-tomcat-9.0.8.tar.gz
[root@lanzhiyong local]# mv apache-tomcat-9.0.8 apache2
[root@lanzhiyong local]# mv apache2 /usr/local/
[root@lanzhiyong src]# cd /usr/local/
[root@lanzhiyong local]# ln -s apache2/ tomcat2
[root@lanzhiyong local]# ln -s apache-tomcat-9.0.8/ tomcat
[root@lanzhiyong local]# ll
//分别给tomcat,tomcat2写一个java页面
[root@lanzhiyong ~]# vim index.jsp
[root@lanzhiyong ~]# cat index.jsp

<%
out.println("Hellow World");
%>
[root@lanzhiyong ~]# mv index.jsp index
[root@lanzhiyong ~]# vim index.jsp

[root@lan conf]# vim /usr/local/nginx/conf/nginx.conf
//添加以下模块

server 192.168.209.12:8081;

[root@lan conf]# nginx -s reload
验证：输入：192.168.209.13 实现nginx静态访问
最后验证输入：192.168.209.13/test/index.jsp 刷新看效果,,实现动静分离
