(运维)--应用服务器部署

Posted 2022-11-27 YX_blog

在现有的tomcat+nginx 配置

– add by yx
15.6环境下
目前已经存在了 应用test2已经搭建完成

配置服务器

我们以新建一个test为例

## 进入目录
cd  /home/tomcat/servers
## copy一份 test 服务器
cp -R  test2 test3
cd test3
## 查看目录
ll ./
## war包存放位置 webapps
## 日志文件存放 logs
## 配置文件存放 conf
## 修改对应的端口
cd conf 
## 修改数据源 <Resource 标签，具体可以参考其他项目搭建
vim context.xml

**查看对应的配置文件 server.conf **

#tomcat实例目录
#export CATALINA_BASE=/home/alpha/servers/"$NAME"

#设置JVM内存大小
export JAVA_OPTS="-Xms2048m -Xmx2048m"

#这里指定的是项目所独有的环境变量
#export RUN_ENV="test"
export JAVA_OPTS="$JAVA_OPTS -Dspring.profiles.active=test"

#远程调试
export JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=46900,server=y,suspend=n"
#jmx
export JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=45660 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -DrestTable=false "

[========]

## 修改对应的端口  因为服务器中部署了多台，所以端口需要不一样 ，修改点2处 Server  port  + Http prot端口 我这里是 http-->6099
vim server.xml 
## 配置启动参数、远程调用等端口，如果不需要可以注释
vim server.xml
## webapps 因为之前的war 在里面，就没有添加，如果是其他项目，直接更换就好了
## 启动项目--发现没有bin目录 因为数据被bin隐藏了。建立一个软连接即可
ln -s /etc/init.d/tomcat8 test3

## 查看日志
cd /home/tomcat/servers/test3/logs
## 清理之前的日志
rm -rf *  
## 启动项目 
service test3 status
service test3 start
## 查看日志
tail -f catalina.out
## 没报错表示成功启动

##配置nginx

## 配置nginx 进入主目录 root 权限
 cd /usr/local/nginx
 ## 开始配置nginx 
 cd conf
 ## 复制配置文件
 cp test2.conf  test3.conf
 ## 编辑test3.conf
 vim test3.conf 

test3.conf 具体如下

#test2
 server 
        listen       80; # 默认监听80端口
        server_name  yx.test3.service.cn; ## yx 这个表示配置的域名访问
        charset utf-8;
        #access_log  logs/host.access.log  main;
        error_page 405 = $uri;

        location / 
            root   html/test;
            index  index.html index.html;
        

        location /test/ 
           proxy_redirect off;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           client_max_body_size 55m;
           proxy_read_timeout      120;
           proxy_pass http://test3;  ## yx 这个与 nginx.config 的upstream配合使用
        


         location /test_res 
            expires  3d; ## 静态资源缓存时间
            alias  /data2/test2 ;## 因为这里是和test2共用的，所以就直接使用即可，其他的直接修改即可 。动静分离
            autoindex on;
        

        #error_page  404              /404.html;

        error_page   500 502 503 504  /50x.html;

        location = /50x.html 
            root   html;
        
 

##配置nginx 并且引入test3.conf
 vim nginx.conf

    upstream test3
        server 192.168.15.6:6099;
        

    include test3.conf;

## 重启nginx
## nginx 平滑重启
  /usr/local/nginx/sbin/nginx  -s reload

通知运维将我们配置的域名统一
yx.test3.service.cn 配置进入dns 即可。
如果本地想要看效果，直接配置hosts 也可以

ip yx.test3.service.cn
就可以直接访问了。
