lnmt 架构
1.nginx 安装
//首先请确保本地仓库可用
//创建系统用户nginx
[root@localhost ~]# useradd -r -M -s /sbin/nologin nginx
//安装依赖环境
[root@localhost ~]# yum -y install pcre-devel openssl openssl-devel gd-devel
[root@localhost ~]# yum -y groups mark install 'Development Tools'
//创建日志存放目录
[root@localhost ~]# mkdir -p /var/log/nginx
[root@localhost ~]# chown -R nginx.nginx /var/log/nginx
//下载nginx
[root@localhost ~]# cd /usr/src/
[root@localhost src]# wget http://nginx.org/download/nginx-1.14.0.tar.gz
//编译安装
[root@localhost src]# tar xf nginx-1.14.0.tar.gz
[root@localhost src]# cd nginx-1.14.0
[root@localhost nginx-1.14.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx
--with-debug --with-http_ssl_module --with-http_realip_module --withhttp_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
……过程略
[root@localhost nginx-1.14.0]# make -j $(grep 'processor' /proc/cpuinfo | wc -l) &&make install
……过程略
//配置
[root@localhost ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' >/etc/profile.d/nginx.sh
[root@localhost ~]# . /etc/profile.d/nginx.sh
[root@localhost ~]# nginx
[root@localhost ~]# ss -antl

2.mysql 安装
//安装依赖包
[root@localhost ~]# yum -y install ncurses-devel openssl-devel openssl cmake mariadb-deve
……下载过程略
//创建用户与组
[root@localhost ~]# cd /usr/src/
[root@localhost src]# groupadd -r -g 306 mysql
[root@localhost src]# useradd -M -s /sbin/nologin -g 306 -u 306 mysql

[root@localhost src]# tar xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
[root@localhost src]# cd /usr/local/
//创建软连接
[root@localhost 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@localhost local]# chown -R mysql.mysql /usr/local/mysql
//添加环境变量
[root@localhost ~]# echo 'export PATH=/usr/local/mysql/bin:$PATH' >/etc/profile.d/mysql.sh
[root@localhost ~]# source /etc/profile.d/mysql.sh
//建立数据存放目录
[root@localhost ~]# mkdir /opt/data
[root@localhost ~]# chown -R mysql.mysql /opt/data/
//初始化数据库 注意这个命令后会生成临时密码 要记住 ！！！！
[root@lanzhiyong ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/opt/data/

3.tomcat 安装
//关闭防火墙
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@localhost ~]# vim /etc/selinux/config
**//将第六行中的 enforcing 改为 disabled**
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
[root@localhost ~]# setenforce 0
//安装之前请确保本地仓库可用
//安装jdk环境
[root@localhost ~]# yum -y install java-1.8.0*

//将prot后的8005端口改为你想改的。
4.nginx 配置与验证
//添加下面模块（负载均衡，轮询）
upstream tomcat {
server 192.168.206.130:8080;
server 192.168.206.130:8081;
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
//单独在添加一个location模块（反向代理，tomcat动态访问）
location ~*\.(do|jsp)$ {
proxy_pass http://tomcat;
}
..........
..........
[root@super ~]# nginx -t

在浏览器上验证输入：192.168.206.130/test/index.jsp
然后可以刷新看效果。
