• 实验环境：

? ansible： 192.168.116.101/24

? nexus私服： 192.168.116.102/24

? Tomcat1： 192.168.116.103/24

? Tomcat2： 192.168.116.104/24

? Nginx1： 192.168.116.105/24

? Nginx2： 192.168.116.106/24

? keeplived： 192.168.116.150/24

? keeplived-M： 192.168.116.105/24

? keeplived-S： 192.168.116.105/24

1. 部署ansible

? 通过 ansible playbook 实现以上服务 的安装与配置

1）安装部署 ansible

	[root@localhost ~]# yum -y install epel-release 		# 安装系统扩展源?	[root@localhost ~]#  yum makecache fast					# 新建缓存?	[root@localhost ~]# yum -y install ansible				# 安装ansible

·

2） 部署 SSH 免密登陆

?

	[root@localhost ~]# ssh-keygen ?	[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.116.103?	[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.116.104?	[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.116.105?	[root@localhost ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.116.106

3) 编辑 hosts 清单

	[root@localhost ~]# vim /etc/ansible/hosts [tomcatservers]192.168.116.103192.168.116.104[tomcat-1]192.168.116.103[tomcat-2]192.168.116.104[nginxservers]192.168.116.105192.168.116.106[keepalived-m]192.168.116.105[keepalived-s]192.168.116.106

4） 编写Tomcat playbook

?

- hosts: tomcatserversremote_user: roottasks:- name: tar javaunarchive: src=/root/jdk-8u201-linux-x64.tar.gz dest=/usr/src- name: mv javashell: mv /usr/src/jdk1* /usr/local/java- name: bina lianglineinfile: path=/etc/bashrc insertafter=EOF line="export JAVA_HOME=/usr/local/java"- name: bina lianglineinfile: path=/etc/bashrc insertafter=EOF line="export JRE_HOME=/usr/local/java/jre"- name: bina lianglineinfile: path=/etc/bashrc insertafter=EOF line="export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib"- name: bina lianglineinfile: path=/etc/bashrc  insertafter=EOF line="export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME:/bin"- name: source bashrcshell: source /etc/bashrc- name: jie tomcatunarchive: src=/root/apache-tomcat-8.5.35.tar.gz dest=/usr/src- name:  move tomcatshell: mv /usr/src/apache-tomcat* /usr/local/tomcat- name: tar mavenunarchive: src=/root/apache-maven-3.6.0-bin.tar.gz dest=/usr/src- name: mv mavenshell: mv /usr/src/apache-maven-3.6.0 /usr/local/maven- name: bina liang lineinfile: path=/etc/bashrc insertafter=EOF line="export PATH=$PATH:/usr/local/maven/bin"- name: delete settings.xmlfile: path=/usr/local/maven/conf/settings.xml state=absent- name: aliyuncopy: src=/root/settings.xml dest=/usr/local/maven/conf/- name: create webappshell: mvn archetype:generate -DgroupId=cn.kgc.kgcweb -DartifactId=kgcweb -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=falseargs:chdir: /root- name: mvn package shell: mvn packageargs:chdir: /root/kgcweb- name: copy kgcwev.warcopy: src=/root/kgcweb/target/kgcweb.war dest=/usr/local/tomcat/webapps/ remote_src=yes- name: copy shcopy: src=/root/tomcat_start.sh dest=/root/- name: start tomcatshell: sh /root/tomcat_start.sh- hosts: tomcat-1remote_user: roottasks:- name: update index.jsplineinfile: path=/usr/local/tomcat/webapps/kgcweb/index.jsp insertafter="hello world" line="This is the Tomcat-1 server"- hosts: tomcatserversremote_user: roottasks:- name: start tomcatshell: sh /root/tomcat_start.sh
