一 生成war包并给数据库导入数据
1.1生成war包
点两下这个package,就会在target目录下生成一个war包
把这个warb包拿出来,放在桌面上备用
1.2 向数据库中导入数据
数据多的话,选择sql文件,直接运行
数据导入成功了
二 启动Tomcat
[root@localhost bin]# ./startup.sh
Using CATALINA_BASE: /usr/tomcat2/apache-tomcat-7.0.68
Using CATALINA_HOME: /usr/tomcat2/apache-tomcat-7.0.68
Using CATALINA_TMPDIR: /usr/tomcat2/apache-tomcat-7.0.68/temp
Using JRE_HOME: /usr/java/jdk1.8.0_261/
Using CLASSPATH: /usr/tomcat2/apache-tomcat-7.0.68/bin/bootstrap.jar:/usr/tomcat2/apache-tomcat-7.0.68/bin/tomcat-juli.jar
Tomcat started.
[root@localhost bin]# cd /usr/tomcat/apache-tomcat-7.0.68/bin
[root@localhost bin]# ./startup.sh
Using CATALINA_BASE: /usr/tomcat/apache-tomcat-7.0.68
Using CATALINA_HOME: /usr/tomcat/apache-tomcat-7.0.68
Using CATALINA_TMPDIR: /usr/tomcat/apache-tomcat-7.0.68/temp
Using JRE_HOME: /usr/java/jdk1.8.0_261/
Using CLASSPATH: /usr/tomcat/apache-tomcat-7.0.68/bin/bootstrap.jar:/usr/tomcat/apache-tomcat-7.0.68/bin/tomcat-juli.jar
Tomcat started.
8080和8081都可以
三 配置负载均衡并启动Nginx
1.cent121这台虚拟机上
虚拟机的位置:
http://192.168.80.121:8081/lg_visualization/view/index.html
nginx的位置 /usr/local/nginx/conf
两台虚拟机所在的位置:
tomcat
/usr/tomcat/apache-tomcat-7.0.68
Tomcat2
/usr/tomcat2/apache-tomcat-7.0.68
2.检测两个tomcat的运行状态
运行状态良好
http://192.168.80.121:8080/lg_visualization/view/index.html
3.配置nginx
首先在
/usr/local/nginx/conf
修改nginx里的nginx.conf文件
upstream vis{ # 用server定义 HTTP地址
server 192.168.80.121:8081;
server 192.168.80.121:8080; }
server {
listen 80;
server_name www.vis.com ;
location / {
# 利用 proxy_ pass可以将请求代理到upstream命名的HTTP服务
proxy_pass http://vis;
index login.html ; }
}
到hosts文件中修改
C:\Windows\System32\drivers\etc
4.启动
4.1 nginx报错
nginx启动报错:nginx: [error] open() “/var/run/nginx/nginx.pid“ failed (2: No such file or directory) 的解决
events下面加一句
pid 加路径名
文章来源:https://www.toymoban.com/news/detail-427756.html
(1)进入 cd /usr/local/nginx/conf/ 目录,编辑配置文件nginx.conf ;
(2)在配置文件中有个注释的地方: #pid logs/nginx.pid;
(3)将注释放开,并修改为:pid /usr/local/nginx/logs/nginx.pid;
(4)在 /usr/local/nginx 目录下创建 logs 目录:mkdir /usr/local/nginx/logs
(5)再次启动nginx服务:cd /usr/local/nginx/sbin/ 问题解决
4.2 成功启动项目
