23.網市場雲建站系統部署

1.安裝Tomcat並配置啟動

1.yum安裝maven和java:
    [root@web01 ~]# yum install java maven -y
    
2.二進位安裝tomcat
    [root@web01 ~]# mkdir /soft && cd /soft
    [root@web01 soft]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.26/bin/apache-tomcat-9.0.26.tar.gz
    [root@web01 soft]# tar xf apache-tomcat-9.0.26.tar.gz 
    [root@web01 soft]# ln -s /soft/apache-tomcat-9.0.26 /soft/tomcat
    [root@web01 soft]# /soft/tomcat/bin/startup.sh
    [root@web01 soft]# netstat -lntp|grep java
    tcp6       0      0 :::8009            :::*        LISTEN      8500/java           
    tcp6       0      0 :::8080            :::*        LISTEN      8500/java           
    tcp6       0      0 127.0.0.1:8005     :::*        LISTEN      8500/java    

2.Tomcat部署項目--->>網市場

1.配置server.xml文件 ,新增在 engline內

  <Host name="cms.cheng.com"  appBase="/code/cms"
        unpackWARs="true" autoDeploy="true">

    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
           prefix="cms_access_log" suffix=".txt"
           pattern="%h %l %u %t &quot;%r&quot; %s %b" />

2.創建站點目錄,上傳源碼包

[root@web01 ~]# mkdir /code/cms
[root@web01 ~]# cd /code/cms/
[root@web01 cms]# rz mail_osc-wangmarket-master.zip 
[root@web01 cms]# unzip mail_osc-wangmarket-master.zip

3.使用mvn編譯

[root@web01 cms]# cd wangmarket/
[root@web01 wangmarket]# mvn clean package -Dmaven.skip.test=true
[root@web01 wangmarket]# cp target/wangmarket.war /code/cms/    
[root@web01 cms]# mv wangmarket.war ROOT.war

4.Nginx配置反向代理

[root@web01 conf.d]# cat cms.cheng.com.conf
server {
    listen 80;
    server_name cms.cheng.com;
    
    location / {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header Host $http_host;
    }
}
[root@web01 conf.d]# nginx -t
[root@web01 conf.d]# systemctl restart nginx

5.重啟Tomcat服務

[root@web01 cms]# /soft/tomcat/bin/shutdown.sh && /soft/tomcat/bin/startup.sh && tail -f /soft/tomcat/logs/catalina.out

6.配置功能變數名稱解析

cms.cheng.com 10.0.0.7

7.安裝圖解：

8.部署多節點組建集群

[root@web01 cms]# scp -rp /code [email protected]:/
[root@web01 cms]# scp -rp /soft [email protected]:/
[root@web02 soft]# rm -rf tomcat/
[root@web02 soft]# ln -s /soft/apache-tomcat-9.0.26 /soft/tomcat
[root@web01 cms]# scp -rp /etc/nginx/conf.d/cms.cheng.com.conf [email protected]:/etc/nginx/conf.d/
[root@web02 soft]# nginx -t
[root@web02 soft]# systemctl restart nginx
[root@web02 soft]# yum install java -y
[root@web02 soft]# /soft/tomcat/bin/startup.sh 
測試：
cms.cheng.com  10.0.0.8

9.接入負載均衡

[root@lb01 conf.d]# cat proxy_cms.cheng.com.conf
upstream cms {
    server 172.16.1.7:8080;
    server 172.16.1.8:8080;
}

server {
    listen 80;
    server_name cms.cheng.com;
    
    location / {
    proxy_pass http://cms;
    include proxy_params;
    }
}
[root@lb01 conf.d]# nginx -t
[root@lb01 conf.d]# systemctl restart nginx

10.通過瀏覽器訪問發現無法登陸

11.Nginx+Tomcat集群會話共用 redis

1.下載TomcatClusterRedisSessionManager (所有web集群都需要操作)
[root@web01 ~]# unzip tomcat-cluster-redis-session-manager.zip
[root@web01 ~]# cd tomcat-cluster-redis-session-manager/
1.拷貝jar包
[root@web01 tomcat-cluster-redis-session-manager]# cp lib/* /soft/tomcat/lib/
2拷貝tomcat連接redis配置文件
[root@web01 tomcat-cluster-redis-session-manager]# cp conf/redis-data-cache.properties /soft/tomcat/conf/
3修改redis-data-cache.properties
[root@web01 tomcat-cluster-redis-session-manager]# vim /soft/tomcat/conf/redis-data-
redis.hosts=172.16.1.52:6379

4.添加如下兩行至tomcat/conf/context.xml
[root@web01 ~]# vim /soft/tomcat/conf/context.xml
<Context>
    .....
    <Valve className="tomcat.request.session.redis.SessionHandlerValve" />
    <Manager className="tomcat.request.session.redis.SessionManager" />
    ....
</Context>

5.修改tomcat/conf/web.xml 配置文件session的超時時間 ,單位是分鐘
<session-config>
        <session-timeout>60</session-timeout>       #根據情況調整
</session-config>

12.安裝redis，當然也可以自行搭建redis集群，anyway

[root@redis ~]# yum install redis -y
[root@redis ~]# cat /etc/redis.conf
...
bind 172.16.1.51 172.16.1.52
requirepass 123456              #如果不需要密碼,則不要配置
...
[root@redis ~]# systemctl start redis
[root@redis ~]# systemctl enable redis

13.重啟多台機器的Tomcat

[root@web01 ~]# /soft/tomcat/bin/shutdown.sh 
[root@web01 ~]# /soft/tomcat/bin/startup.sh

14.在172.16.1.51的資料庫上,創建一個wangmarket的庫,配置授權訪問用戶

[root@db01 ~]# mysql -uroot -p000000
MariaDB [(none)]> create database wangmarket charset utf8;
MariaDB [(none)]> grant all privileges on *.* to 'all'@'%' identified by '000000';
MariaDB [(none)]> flush privileges;
