How to deploy tomcat in batches with ansible

1.1 Building the Directory Structure

This operation is to install the directory structure of nginx+mysql+tomcat+db. You can refer to it. It's good~

mkdir -p /ansible/roles/{nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars}

defaults default search path
tasks stores playbooks path
files stores files and script packages, copy module file search path
templates Template storage path
Handlers notify calls some playbook storage paths
vars roles variable storage path

1.2 File Directory Structure

[root@qtbackup ~]# tree /ansible/
/ansible/

 [root@qtbackup ~]#

1.3 Create a general call file in the ansible directory

- hosts: bgo ####This is the host group name defined by hosts. If it is a single host, you can directly write the address remote_user: root ####Execution user roles: #####Explanation of the configuration file directory, because we are installing tomcat this time, so comment out the others # - nginx
 # -mysql
  - tomcat
 # - db

1.4 Create a tomcat installation playbook file

vim /ansible/roles/tomcat/tasks/main.yml

#This is to install jdk using the yum module. If necessary, you can use #- name: install java
# yum: name=java-1.8.0-openjdk.x86_64 state=present

===============================================================
#Create user- name: group
 group: name=tomcat
- name: user
 user: name=tomcat group=tomcat home=/usr/tomcat
 sudo: True

################################This source package installs JDK###############################
#Copy jdk to the tmp directory - name: copy jdk-8u73-linux-x64.gz
 copy: src=jdk-8u73-linux-x64.gz dest=/tmp/jdk-8u73-linux-x64.gz
#Unzip the jdk package to /application
- name: Extract archive jdk
 command: /bin/tar xf /tmp/jdk-8u73-linux-x64.gz -C /application
#Rename - name: java
 shell: mv /application/jdk1.8.0_73 /application/java
#Add environment variables - name: add /etc/profile
 lineinfile: dest=/etc/profile regexp="^JAVA_HOME=" line="JAVA_HOME=/application/java/"
- name: add /etc/profile
 lineinfile: dest=/etc/profile regexp="^CLASS_PATH=" line="CLASS_PATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib"
- name: add /etc/profile
 lineinfile: dest=/etc/profile regexp="^PATH=\$PATH:\$JAVA_HOME" line="PATH=$PATH:$JAVA_HOME/bin"
- name: add /etc/profile
 lineinfile : dest=/etc/profile regexp="^export JAVA_HOME" line="export JAVA_HOME"

############################Install tomcat##########################################
- name: copy tomcat_tar_gz
 copy: src=apache-tomcat-8.0.29.tar.gz dest=/tmp/apache-tomcat-8.0.29.tar.gz
#Unzip tomcat to the opt directory - name: Extract archive
 command: /bin/tar xf /tmp/apache-tomcat-8.0.29.tar.gz -C /opt
#Create a soft link - name: Symlink install directory
 file: src=/opt/apache-tomcat-8.0.29/ dest=/application/tomcat state=link
#Give directory permissions - name: Change ownership of Tomcat installation
 file: path=/application/tomcat/ owner=tomcat group=tomcat state=directory recurse=yes
#Push configuration file - name: Configure Tomcat users
 template: src=tomcat-users.xml dest=/application/tomcat/conf/
 notify: restart tomcat
#Install tomcat. init startup script - name: Install Tomcat init script
 copy: src=tomcat-initscript.sh dest=/etc/init.d/tomcat mode=0755
#Start tomcat
- name: Start Tomcat
 service:name=tomcat state=started enabled=yes

1.5 Calling handlers via notify

- name: restart tomcat 
 service:name=tomcat state=restarted

1.6 Syntax Check === Execute Installation

cd /ansible
ansible-playbook web.yml --syntax-check #Check syntax ansible-playbook web.yml #Execute
