1. ✅tomcat与nginx结合

1.1. 🎯接入nginx

  • 静态资源(html|js|css|jpg|jpeg|bmp)交给nginx处理，其他的转发给tomcat处理
1.修改yum源
vim /etc/yum.repos.d/nginx.repo 
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true2.安装nginx
yum -y install nginx3.修改nginx配置文件
vim /etc/nginx/conf.d/zrlog.zhubl.xyz.conf 
server {listen 80;server_name zrlog.zhubl.xyz;error_log /var/log/nginx/zrlog-error.log notice;access_log /var/log/nginx/zrlog-access.log main;location / {proxy_pass http://127.0.0.1:8080;proxy_set_header Host $http_host;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header X-Real_Ip $remote_addr;}location ~* \.(html|js|css|jpg|jpeg|bmp)$ {root /app/tools/tomcat/webapps/ROOT/;expires 7d;}
}4.重启nginx
systemctl reload nginx5.修改站点目录权限
find /app/tools/tomcat/webapps -type f |xargs chmod 644
find /app/tools/tomcat/webapps -type d |xargs chmod 755

1.2. 📁数据库连接文件

[root@web03 /app/tools/tomcat]# cat webapps/ROOT/WEB-INF/db.properties 
#This is a database configuration file
#Thu Jul 03 09:20:43 CST 2025
driverClass=com.mysql.cj.jdbc.Driver
user=zrlog
password=lidao
jdbcUrl=jdbc\:mysql\://172.16.1.51\:3306/zrlog?characterEncoding\=UTF-8&allowPublicKeyRetrieval\=true&useSSL\=false&serverTimezone\=GMT
