ansible批量部署nginx、mysql、tomcat

ansible安装与核心组件详解：http://www.cnblogs.com/Carr/p/7446917.html

ansible初始化配置：
1、修改/etc/ansible/hosts配置文件，在尾部添加内容
vim /etc/ansible/hosts
[203] #自定义组名
192.168.0.203 #客户端IP地址
hostname #主机名（前提有DNS域名解析或者修改/etc/hosts文件添加内部解析）

注意：如果不配置/etc/ansible/hosts添加客户端IP，在执行ansible命令时，会报错

通过ansible远程批量安装服务
1、ansible安装（nginx、tomcat、mysql）
在一个IP上，安装一个NGINX，一个TOMCAT,一个MYSQL
Nginx 的 80 口反向代理到 tomcat 的 8080口
Mysql里面有db : students , table : profile, 两个字段: name , age
Insert 一行 到mysql ,”Teddy”, “12”

2、构建目录结构
mkdir -p /home/cudo/ansible_server/roles/{nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars}
●defaults 默认寻找路径
●tasks 存放playbooks路径
●files 存放文件和脚本，copy模块文件搜索路径
●templates 模版存放路径
●handlers notify调用部分playbook存放路径
●vars roles内变量存放路径

3、文件结构
tree /home/cudo/ansible_server/roles/
/home/cudo/ansible_server/roles/

│ │ └── stu.sql #要导入的sql

5、执行安装 & 检查

cd /home/cudo/ansible_server
ansible-playbook web.yml --syntax-check  #检查语法
ansible-playbook web.yml  #执行

二进制免编译安装mysql

- name: install mysql
  shell: /bin/bash /tmp/mysql_install.sh
/home/cudo/ansible_server/roles/mysql2/files/mysql_install.sh
#!/bin/bash

####定义mysql数据库路径，和mysql登录密码
DBDIR='/data'
PASSWD='ever2016'

####判断数据目录是否存在如果不存在递归创建目录
[ -d $DBDIR ] || mkdir $DBDIR -p

####安装mysql组件
yum install cmake make gcc-c++ bison-devel ncurses-devel libaio 'perl(Data::Dumper)' -y
id mysql &> /dev/null

####如果执行id mysql输出为0 那么就是执行正确创建mysql用户
if [ $? -ne 0 ];then
 useradd mysql -s /sbin/nologin -M
fi

####切换到tmp目录，解压mysql到/usr/local
cd /tmp/
tar -zxf mysql-5.6.16.tar.gz -C /usr/local/
tar -zxf 3306.tar.gz -C /data/

####赋予数据目录权限
chown -R mysql.mysql $DBDIR
chown -R mysql.mysql /usr/local/mysql-5.6.16

####初始化mysql
/usr/local/mysql-5.6.16/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysqldata/3306/data --user=mysql

####如果mysql初始化失败提示install mysql is failed! 退出安装mysql
if [ $? -ne 0 ];then
 echo "install mysql is failed!" && /bin/false
 exit 1
fi

####执行权
chmod 700 /data/mysqldata/3306/mysqld

####启动mysql
/data/mysqldata/3306/mysqld start
sleep 5

####更新数据库用户密码
/usr/local/mysql-5.6.16/bin/mysql -S /data/mysqldata/3306/mysql.sock -e "update mysql.user set password=password('$PASSWD') where host='localhost' and user='root';"
/usr/local/mysql-5.6.16/bin/mysql -S /data/mysqldata/3306/mysql.sock -e "update mysql.user set password=password('$PASSWD') where host='127.0.0.1' and user='root';"
/usr/local/mysql-5.6.16/bin/mysql -S /data/mysqldata/3306/mysql.sock -e "delete from mysql.user where password='';"
/usr/local/mysql-5.6.16/bin/mysql -S /data/mysqldata/3306/mysql.sock -e "flush privileges;"
if [ $? -eq 0 ];then
 echo "ins_done"
