1.构建安装目录

mkdir -p /ansible/roles/mysql/{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

2.文件目录结构

3.playbooks & Shell

/etc/ansible/roles/mysql/files/install_mysql.sh脚本内容为：

#!/bin/bash
#
DBDIR='/data/mysql/'
PASSWD='fanshine123'
[ -d $DBDIR ] || mkdir $DBDIR -p
id mysql &> /dev/null
if [ $? -ne 0 ];thenuseradd mysql -s /sbin/nologin -M
fi
chown -R mysql.mysql $DBDIR
cd /tmp/
tar xf mysql-5.6.13.tar.gz
cd mysql-5.6.13
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=$DBDIR \
-DMYSQL_UNIX_ADDR=$DBDIR/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EMBEDDED_SERVER=1
if [ $? != 0 ];thenecho "make error!"exit 1
fi
make && make install
if [ $? -ne 0 ];thenecho "install mysql is failed!" && /bin/false
fi
sleep 2
ln -s /usr/local/mysql/bin/* /usr/bin/
cp -f /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
cp -f /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 700 /etc/init.d/mysqld
/usr/local/mysql/scripts/mysql_install_db  --basedir=/usr/local/mysql --datadir=$DBDIR --user=mysql
if [ $? -ne 0 ];thenecho "install mysql is failed!" && /bin/false
fi
/etc/init.d/mysqld start
if [ $? -ne 0 ];thenecho "install mysql is failed!" && /bin/false
fi
chkconfig --add mysqld
chkconfig mysqld on
/usr/local/mysql/bin/mysql -e "update mysql.user set password=password('$PASSWD') where host='localhost' and user='root';"
/usr/local/mysql/bin/mysql -e "update mysql.user set password=password('$PASSWD') where host='127.0.0.1' and user='root';"
/usr/local/mysql/bin/mysql -e "delete from mysql.user where user='';"
/usr/local/mysql/bin/mysql -e "flush privileges;"
if [ $? -eq 0 ];thenecho "ins_done"
fi

/etc/ansible/roles/mysql/tasks/main.yml文件内容为：

- name: copy mysql to clientcopy: src=mysql-5.6.13.tar.gz dest=/tmp/mysql-5.6.13.tar.gz
- name: copy install_script to clientcopy: src=install_mysql.sh dest=/tmp/install_mysql.sh owner=root group=root mode=755
- name: install mysqlshell: /bin/bash /tmp/install_mysql.sh

/etc/ansible/mysql.yml文件内容为：

- hosts: webserver remote_user: rootroles:- mysql

4.执行安装

[root@Centos ansible]# ansible-playbook mysql.yml --syntax-check --检查语法
[root@Centos ansible]# ansible-playbook  mysql.yml --执行安装
