安裝Tomcat

移除apt所安裝的tomcat9

Tomcat 10的版本比Tomcat 9更快更穩定，所以先前若有使用 apt-get 安裝過Tomcat 9的人，請依如下步驟移除。

sudo apt-get purge tomcat9
sudo apt autoremove
sudo rm -rf /etc/tomcat9

下載及安裝

請到 https://tomcat.apache.org/download-10.cgi 下載Core版 .tar.gz檔，然後依如下步驟安裝。

sudo apt-get install openjdk-18-jdk
sudo useradd -m -d /opt/tomcat -U -s /bin/false tomcat
wget https://downloads.apache.org/tomcat/tomcat-10/v10.0.22/bin/apache-tomcat-10.0.22.tar.gz
sudo mkdir /opt/tomcat
sudo tar xzvf apache-tomcat-10.0.22.tar.gz -C /opt/tomcat --strip-components=1
sudo chown -R tomcat:tomcat /opt/tomcat
sudo chmod -R u+x /opt/tomcat/bin

設定啟動服務

sudo vim /etc/systemd/system/tomcat.service，並寫入如下指令

[Unit]
Description=Tomcat
After=network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment="JAVA_HOME=/usr/lib/jvm/java-1.18.0-openjdk-amd64"

Environment="CATALINA_BASE=/opt/tomcat"
Environment="CATALINA_HOME=/opt/tomcat"
Environment="CATALINA_PID=/opt/tomcat/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/opt/tomcat/bin/shutdown.sh

[Install]
WantedBy=multi-user.target

啟用服數及啟動Tomcat

sudo systemctl daemon-reload
sudo systemctl enable tomcat.service
sudo systemctl start tomcat.service
sudo systemctl status tomcat.service

更改網頁根目錄

sudo vim /opt/tomcat/conf/server.xml，新增如下藍色部份

<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />
<Context path="" docBase="/data/server/tomcat" debug="0" reloadable="true"/>
</Host>

Nginx設定

開啟 /etc/nginx/sites-available/default，新增如下藍色的部份即可，將所有 *.jsp的檔案全都轉向給 Tomcat http://localhost:8080

location ~* \.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
#location ~ .*.jsp$ {
location ~* \.jsp$ {
        index index.jsp;
        proxy_pass http://localhost:8080;
}
