一 下载tomcat安装包

~# wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.73/bin/apache-tomcat-8.5.73.tar.gz

二 安装tomcat

~# tar xf apache-tomcat-8.5.73.tar.gz -C /usr/local/
~# ln -sv /usr/local/apache-tomcat-8.5.73/ /usr/local/tomcat
'/usr/local/tomcat' -> '/usr/local/apache-tomcat-8.5.73/'

三 设置环境变量

~# echo 'PATH=/usr/local/tomcat/bin:$PATH' > /etc/profile.d/tomcat.sh
~# . /etc/profile

四 验证版本信息

~# /usr/local/tomcat/bin/version.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
NOTE: Picked up JDK_JAVA_OPTIONS:  --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED

五 启动服务

~# /usr/local/tomcat/bin/catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/local/jdk
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.

六 验证tomcat web界面

ubuntu20.04安装tomcat8_java

七 创建tomcat运行用户

~# groupadd -g 8080 -o -r tomcat
~# useradd -M -N -g tomcat -o -r  -s /sbin/nologin -c "tomcat Server" -u 8080  tomcat
~# chown -R tomcat.tomcat /usr/local/apache-tomcat-8.5.73/

八 设置JAVA_HOME环境变量

~# cat /usr/local/tomcat/conf/tomcat.conf 
JAVA_HOME=/usr/local/jdk

九 设置JAVA_OPTS

~# cat /usr/local/tomcat/conf/tomcat.conf 
JAVA_HOME=/usr/local/jdk
JAVA_OPTS="-server -Xms1g -Xmx1g -Xss512k -Xmn1g -XX:CMSInitiatingOccupancyFraction=65  -XX:+UseFastAccessorMethods -XX:+AggressiveOpts -XX:+UseBiasedLocking -XX:+DisableExplicitGC -XX:MaxTenuringThreshold=10 -XX:NewSize=2048M  -XX:NewRatio=2   -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled"  #-Xms：jvm内存初始值 -Xmx：jvm内存最大值

十 添加tomcat.service文件

~# cat /lib/systemd/system/tomcat.service 
[Unit]
Description=Tomcat
#After=syslog.target network.target remote-fs.target nss-lookup.target
After=syslog.target network.target 

[Service]
Type=forking
EnvironmentFile=/usr/local/tomcat/conf/tomcat.conf
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecStop=/usr/local/tomcat/bin/shutdown.sh
PrivateTmp=true
User=tomcat

[Install]
WantedBy=multi-user.target

十一 设置tomcat开机启动

~# systemctl enable tomcat
Created symlink /etc/systemd/system/multi-user.target.wants/tomcat.service → /lib/systemd/system/tomcat.service.
~# systemctl start tomcat
~# systemctl status tomcat

十二 访问manager

12.1 修改tomcat-users.xml

~# cat /usr/local/tomcat/conf/tomcat-users.xml   #添加以下内容
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<role rolename="manager-jmx"/>
<role rolename="manager-script"/>
<role rolename="manager-status"/>
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui,manager-jmx,manager-script,manager-status"/>

12.2 修改host-manager

~# cat /usr/local/tomcat/webapps/host-manager/META-INF/context.xml 
<?xml version="1.0" encoding="UTF-8"?>

<Context antiResourceLocking="false" privileged="true" >
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
                   sameSiteCookies="strict" />
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />   #设置允许访问的IP地址 allow="^.*$"
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

12.3 修改manager

~# cat /usr/local/tomcat/webapps/manager/META-INF/context.xml 
<?xml version="1.0" encoding="UTF-8"?>

<Context antiResourceLocking="false" privileged="true" >
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
                   sameSiteCookies="strict" />
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="192\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /> #设置允许访问的IP地址 allow="^.*$"
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

12.4 重启tomcat服务

~# systemctl restart tomcat

十三 验证内存设置

 

ubuntu20.04安装tomcat8_apache_02
