centos7安装tomcat8

cd /opt

yum -y install gcc-c++

tar -zxvf /opt/apache-tomcat-8.5.51.tar.gz

mv apache-tomcat-8.5.51/ tomcat-8.5.51

在linux上以服务的方式启动java程序，需要提前安装jsvc。linux是利用daemon(jsvc)构建java守护进程

tar -zxvf commons-daemon-1.1.0-native-src.tar.gz

cd /opt/commons-daemon-1.1.0-native-src/unix

./configure

make#编译生成了可执行的文件 jsvc (在源文件目录的'unix目录下')

将编译好的jsvc文件放到tomcat安装目录下的bin文件夹，并添加权限

cp /opt/commons-daemon-1.1.0-native-src/unix/jsvc /opt/tomcat-8.5.51/bin/jsvc

chmod +x /opt/tomcat-8.5.51/bin/jsvc

useradd easytong

passwd easytong

chown -R easytong:easytong /opt/tomcat-8.5.51/

chmod g+r -R /opt/tomcat-8.5.51/

chmod g+w -R /opt/tomcat-8.5.51/webapps

chmod g+w -R /opt/tomcat-8.5.51/logs

chmod g+w -R /opt/tomcat-8.5.51/work

chmod g+w -R /opt/tomcat-8.5.51/temp

cd /opt/tomcat-8.5.51/bin/

vim daemon.sh

在开头增加以下内容:

# Tomcat init script for Linux

# chkconfig: 2345 96 14

# discription: The Apache Tomcat Server/JSP container

将脚本中tomcat_user启动用户改为easytong

增加java_home和jre_home环境变量

JAVA_HOME=/opt/java/jdk1.8.0_181/

JRE_HOME=/opt/java/jdk1.8.0_181/jre

JAVA_HOME=/opt/java/jdk1.8.0_221/

JRE_HOME=/opt/java/jdk1.8.0_221/jre

export JAVA_HOME=/opt/java/jdk1.8.0_221/

export JAVA_BIN=/opt/java/jdk1.8.0_221/bin/

export JRE_HOME=/opt/java/jdk1.8.0_221/jre

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

将tomcat注册到系统启动项，并启动tomcat进行测试

cd /usr/lib/systemd/system
