ansible部署tomcat8

1312

其实大部分是参考别人的博文做的，自己做了修改
准备
tomcat.tar.gz 经过优化后的


apr模式开启
tomcat都使用root默认目录

文件
tomcat.sh
server.xml

建立一些目录,并赋予权限
/opt/src/logs

启动
sh /opt/ea/tomcat.sh

cat tomcat.sh
#!/bin/bash
JAVA_OPTS="-Xms2048m -Xmx2048m -Xmn384m"
Java_Home=/usr/java/jdk
Tomcat_Home=/opt/ea/tomcat
Tomcat_User=tomcat
chown $Tomcat_User:$Tomcat_User -R /opt/ea/tomcat
chown $Tomcat_User:$Tomcat_User -R /opt/src/logs
JAVA_HOME=`echo $Java_Home`
CATALINA_HOME=`echo $Tomcat_Home`
CATALINA_BASE=`echo $New_instance`
export JAVA_HOME JAVA_OPTS CATALINA_HOME CATALINA_BASE
su `echo $Tomcat_User` $CATALINA_HOME/bin/startup.sh

客户端
/etc/profile新增
export JAVA_HOME=/usr/java/jdk
export JRE_HOME=/usr/java/jdk/jre
exportCLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
export MAVEN_HOME=/usr/java/apache-maven-3.3.1

开始吧
mkdir -p playbook
以下是playbook例子结构
参考ansible部署tomcat及 include机制  写的非常详细。

ansible-playbook -i hosts site.yml



报错
1.server.xml要改
2.-DappHome=/opt/src/xx/db

cat setenv.sh
JAVA_OPTS="$JAVA_OPTS -DappHome=/opt/src/xx/db"

3.start启动时启动不了的，因为没有环境变量，所以只能用脚本

4.var 变量例子参考
Listen {{listen.0}}:{{listen.1}}
listen:
  - "{{ansible_all_ipv4_addresses.0}}"
  - 8080
host_fqdn:
  - "{{ansible_nodename}}"


5.测试
echo "abcdefg" >> roles/http/meta/test/test.html
ansible-playbook -i hosts site.yml --tags=updateconf
http://ip:8080/test/test.html

.start启动时启动不了的，因为没有环境变量，所以只能用脚本   ，这里有个疑问   ，如果说使用playbook的话 环境变量应该如何设置。
