Estou tentando instalar o tomcat em uma nova máquina virtual do CentOS 7. Instalei com êxito o httpd apache e consigo obter a página de teste do apache quando digito o ip da máquina virtual em um navegador da Web em outro computador na rede. Mas estou recebendo a seguinte mensagem de erro quando digito systemctl start tomcat
:
Job for tomcat.service failed. See 'systemctl status tomcat.service' and 'journalctl -xn' for details.
Aqui está o histórico completo de comandos na instalação do java e do tomcat:
Primeiramente, instalei o java usando as instruções deste tutorial porque as instruções do tomcat (segundo bloco abaixo) queriam que eu usasse o openjdk, e eu preciso usar o java real:
//Install Java
# cd /opt/
# yum install wget
# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u60-b27/jdk-8u60-linux-x64.tar.gz"
# tar xzf jdk-8u60-linux-x64.tar.gz
# cd /opt/jdk1.8.0_60/
# alternatives --install /usr/bin/java java /opt/jdk1.8.0_60/bin/java 2
# alternatives --config java
(Select the version you want)
# alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_60/bin/jar 2
# alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_60/bin/javac 2
# alternatives --set jar /opt/jdk1.8.0_60/bin/jar
# alternatives --set javac /opt/jdk1.8.0_60/bin/javac
# java -version (checks to see you install correct version)
# export JAVA_HOME=/opt/jdk1.8.0_60
# export JRE_HOME=/opt/jdk1.8.0_60/jre
# export PATH=$PATH:/opt/jdk1.8.0_60/bin:/opt/jdk1.8.0_60/jre/bin
Observe que o tutorial anterior não explica como colocar as variáveis de ambiente em /etc/environment
, então parei antes desse comando.
Os seguintes comandos são de este outro tutorial . Eu comecei no ponto depois de instalar o java:
//Install Tomcat
Login as sudo user, not root.
# sudo groupadd tomcat
# sudo useradd -M -s /bin/nologin -g tomcat -d /opt/tomcat tomcat
# cd ~
# wget http://mirrors.gigenet.com/apache/tomcat/tomcat-8/v8.0.27/bin/apache-tomcat-8.0.27.tar.gz
# sudo mkdir /opt/tomcat
# sudo tar xvf apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1
# cd /opt/tomcat
# sudo chgrp -R tomcat conf
# sudo chmod g+rwx conf
# sudo chmod g+r conf/*
# sudo chown -R tomcat work/ temp/ logs/
# sudo vi /etc/systemd/system/tomcat.service

Fazendo yum localinstall
de um jdk rpm atualizado, como sugerido nesta outra postagem , não funcionou.
EDITS:
Como sugestão de @ Bram, eu mudei o arquivo de configuração para o seguinte, mas ainda estou recebendo o mesmo erro:
# Systemd unit file for tomcat
[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target
[Service]
Type=forking
Environment=JAVA_HOME=/opt/jdk1.8.0_60
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'
ExecStart=/opt/tomcat/bin/startup.sh
ExecStop=/bin/kill -15 $MAINPID
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target
Além disso, conforme o comentário de JeffSchaller no bate-papo, eu consegui fazer com que o tomcat começasse nativamente da seguinte forma:
[user@localhost tomcat]$ sudo /opt/tomcat/bin/startup.sh
Using CATALINA_BASE: /opt/tomcat
Using CATALINA_HOME: /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME: /
Using CLASSPATH: /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.
[user@localhost tomcat]$
Assim, o problema neste OP parece estar na configuração do systemd. Como posso consertar isso?
