1 自动化安装配置各类mysql相关环境
之前有人对我说：“安装一个mysql这么容易的事还要写个工具？半个小时就能解决的事！” 你打算每次都手工做吗？ ... 我想说“年轻人你的思想很危险啊！” 1、 这样发展下去第2、第3 ... 第100 个的时候都还是要花你半小时、你的生产力没有提高呀！ 2、 你的输出只是一碗“蛋炒饭”、这碗”蛋炒饭"好不好吃、很大一部分取决你炒它时的心情；想想KFC的汉堡、它只要做出一个 80分的汉堡，然而再把这个汉堡的制作流程记录下来、以后的每个汉堡都完全按这个程序走、每汉堡都是80分的；如果以后找到 了流程中可以改进的地方、就可以把输出汉堡的质量再提高； 最大的好处在于这个上过程中没有减法、只有加法。 -
2 自动化监控各类mysql相关环境
高质量的安装好各类mysql环境只是一个好的开始、mysqltools不只能在安装这个阶段大大的节约mysql-dba要花费的时间、 还能在mysql整个生命周期中监控mysql、做到有问题早发现、早解决、常见问题自动解决。让dba的时间用到更有价值的地方。 -

总的来说标准化是自动化的基础，没有标准化就谈不上自动化。举个例子，比较说我管理着400多台mysql主机，现在由于一些安全方面的问题要对这400多台主机上的mysql进行升级；如果个400台主机上的mysql它们的安装目录、配置文件、都各有各的特色； 比如有的安装在/usr/local/mysql，有的安装在/home/mysql/mysql/，有的又安装在/var/mysql/，这样的话就不能用同一个升级步骤去应对所有的主机，这就意味着不能批量的对这400台主机做升级了。
mysqltools 提供的自动化，集中化运维能力是建立在ansible的基础之上，所以安装ansible 就成了使用mysqltools先决条件； ansible 这个软件又是由python写出来的，实际上绝大部分linux操作系统都已经安装上了python2.x，作为一个面向未来的软件 mysqltools并没有使用python2.x而是基于python3.6.x上开发完成的。所以在你安装ansible之前还要先安装上python.3.6.x 好在所以的安装包mysqltool都已经为你准备好了，mysqltools/deploy/packages/目录下；不只是这样，为们还把安装流程写成 了脚本，这样你就只要运行一下mysqltools给出的安装脚本就能自动化安装mysqltools了。
为了方便离线安装python3.6.x 的安装包已经打包到了mysqltools/deploy/packages/python中 注意安装的过程要用root用户
安装python3.6.x 的相关依赖包
yum -y install gcc gcc-c++ libffi libffi-devel zlib zlib-devel openssl openssl-devel libyaml sqlite-devel libxml2 libxslt-devel libxml2-devel
安装python-3.6.x
cd mysqltools/deploy/packages/python
tar -xvf python-3.6.2.tar.xz -C /tmp/
cd /tmp/Python-3.6.2/
./configure --prefix=/usr/local/python-3.6.2/
make -j 2
make install
cd /usr/local/
ln -s /usr/local/python-3.6.2 python
echo 'export PATH=/usr/local/python/bin/:$PATH' >> /etc/profile
source /etc/profile
事实上mysqltools/deplay/packages/python/install.sh 脚本中包涵了上面两个步骤的命令可以用root用户直接运它以完成python的安装
bash install.sh
为了方便离线安装 ansible-2.4.0.0 的安装包和与之相关的依赖包都已经保存到mysqltool/deploy/packages/ansible目录下

作为一个着眼于自动化的工具当然是不应该有这么困难的安装方式的，mysqltools为自己写好自动化安装的脚本，�注意这个要用root身份运行
cd mysqltools/deploy/package/ansible
bash install.sh
安装完python 、ansible 对于mysqltools就已经具备可运行的基础了；你还要配置两个配置项，这样你的mysqltools就能正常运行了。
-
1 mysqltools 的全局配置文件保存在mysqltools/deploy/ansible/std_vars.yaml文件中；所以配置mysqltools就只要改这个文件就行了
-
2 mtls_base_dir 这个变量是mysqltools的基准目录、它的值应该是你进入mysqltools这个上工具后pwd命令所输出的值；注意这人目录要以'/'结尾
例如：你把mysqltools 下载到了/tmp/目录下、那么mtls_base_dir的值就应该是/tmp/mysqltools/
-
3 mysql_packages_dir 由于mysql的安装包过于巨大、所以mysqltools中并没有内置mysql的安装包；mysql的安装包你要自己去官网下载， 然而mysql_packages_dir 就是mysql安装包所在的路径。
例如：你把mysql的安装包下载到了/opt/softwars/mysql/目录下，那么mysql_packages_dir的值就是/opt/softwars/mysql/ 最新mysql-5.7二进制包的下载地址：https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
由于mysqltools是基于ansible开发出为的工具集、所以要熟练的使用mysqltools你要先了解一下ansible
- 1 ansible中文文档：http://www.ansible.com.cn/index.html
- 2 ansible英文文档：http://docs.ansible.com/ansible/latest/index.html
-
1 进入mysql工具所在的目录
cd mysqltools/deploy/ansible/mysql/ -
2 设置install_single_mysql.yaml文件中的hosts字段的值为你要执行mysql包安装的目标机器
-
3 调用ansible-playbook完成自动化安装过程
ansible-playbook install_single_mysql.yaml PLAY [cstudio] **************************************************************************** TASK [Gathering Facts] ******************************************************************** ok: [cstudio] TASK [create mysql user] ****************************************************************** changed: [cstudio] TASK [create and config /etc/my.cnf] ****************************************************** changed: [cstudio] TASK [transfer mysql install package to remote host and unarchive to /usr/local/] ********* changed: [cstudio] TASK [change owner to mysql user] ********************************************************* changed: [cstudio] TASK [make link /usr/local/mysql-xx.yy.zz to /usr/local/mysql] **************************** changed: [cstudio] TASK [export mysql share object (*.os)] *************************************************** changed: [cstudio] TASK [load share object] ****************************************************************** changed: [cstudio] TASK [export path env variable] *********************************************************** changed: [cstudio] TASK [export path env to /root/.bashrc] *************************************************** changed: [cstudio] TASK [make link /usr/local/mysql-xx.yy.zz to /usr/local/mysql] **************************** changed: [cstudio] TASK [create datadir] ********************************************************************* changed: [cstudio] TASK [initialize-insecure] **************************************************************** changed: [cstudio] TASK [create libmysqlclient_r.so file for php-5.6] **************************************** changed: [cstudio] TASK [create systemd config file] ********************************************************* changed: [cstudio] TASK [enable mysqld service] ************************************************************** changed: [cstudio] TASK [start mysql(sytemctl)] ************************************************************** changed: [cstudio] TASK [config mysql.service start up on boot] ********************************************** changed: [cstudio] TASK [config sysv start script] *********************************************************** skipping: [cstudio] TASK [start mysql(service)] *************************************************************** skipping: [cstudio] TASK [config mysql.service start up on boot] ********************************************** skipping: [cstudio] TASK [transfer sql statement to remonte] ************************************************** changed: [cstudio] TASK [make mysql secure] ****************************************************************** changed: [cstudio] TASK [clear /tmp/ directory] ************************************************************** changed: [cstudio] PLAY RECAP ******************************************************************************** cstudio : ok=21 changed=20 unreachable=0 failed=0 -
4 测试mysql数据是否安装成功
[root@cstudio data]# mysql -uroot -pmtls0352 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> -
5 注意事项：
-
1 如果你的目标端操作系统是linux-6.x 而且是最小化安装的情况下会有两个问题出现、原因是缺少selinux-python、numactl 不过可以通过
yum -y install selinux-python numactl把它们行安装一下
-
-
1 进入mysql-group-replication工具所在的目录
cd mysqltools/deploy/ansible/mysql/ -
2 告诉mysqltools你要在哪几台主机上安装mysql-group-replication
比如说我要在10.186.19.{17,18,19}这三个结点上安装，那么就要把vars/group_replication.yaml 的内容改成如下
mtls_with_mysql_group_replication: 1 mysql_binlog_format: row mysql_mgr_port: 33060 mysql_mgr_hosts: - '10.186.19.17' - '10.186.19.18' - '10.186.19.19' -
3 把要安装mysql-group-replication的主机分到一个ansible组中
比如说把上面3个实例分类到一个组中、那么/etc/ansible/hosts文件的内容如下
[mgr1] mrg17 ansible_user=root ansible_host=10.186.19.17 mrg18 ansible_user=root ansible_host=10.186.19.18 mrg19 ansible_user=root ansible_host=10.186.19.19 -
4 修改mysql-group-replication.yaml文件中的hosts变量为mgr1

1 把要安装multi-source-replication的各个主机加入到ansible的一个组中
cat /etc/ansible/hosts [multi_source] mtls16 ansible_user=root ansible_host=10.186.19.16 mtls18 ansible_user=root ansible_host=10.186.19.18 mtls19 ansible_user=root ansible_host=10.186.19.19 -
2 修改mysqltools/deploy/ansible/mysql/vars/multi_source_replication.yaml这个配置文件 这样mysqltools时就知道那些主机是master角色、那个主机是slave角色了。
cat multi_source_replication.yaml #master_ips 定义多个master主机ip组成的列表 master_ips: - '10.186.19.16' - '10.186.19.18' #定义slave的ip slave_ip: '10.186.19.19' -
3 修改mysqltools/deploy/ansible/mysql/install_multi_source_replication.yaml文件中的hosts:变量为 1 中 定义好的组名
cat install_multi_source_replication.yaml | grep hos - hosts: multi_source -

这里介绍的python的安装与前面介绍的安装python所面向的问题是不一样的、安装python是为了 在主控机上安装ansible,mysqltools才安装的python；这里介绍的python安装是在已经安装完成ansible之后，在被控主机上安装 python。之所以要在被控机上安装python是因为mysqltools的大多数功能是用python写的，比如对mysql进行监控时，mysql各项 指标的收集工作是通过python语言来实现的。
-
1 进入安装python的playbook所在的目录

4 测试python3有没有安装成功

5 注意事项
由于mysqltools主要是解决mysql相关的问题、解决问题用到的语言是python、目前mysql官方的python连接mysql驱动 包就是mysql-connector-python 所以mysqltools会在安装python的同时也把这个包也安装上；当然你也可以通过设置 std_vars.yaml配置文件中mtls_with_mysql_conntor_python的值为0 来禁止这一操作
对于mysql的监控mysqltools采用国际一流的开源解决方案(zabbix)来实现、各项监控指标会由zabbix_agent完成收集、并发往zabbix_server、在zabbix_server收到数据后会做一些动作如：数据超过事先设定阈值时会告警，对于每一项收到到的数据zabbix_server都 会把它保存到zabbix自用的后台的数据库中；zabbix为了方便使用还给用户配了一个web界面；当然这个web界面的所有数据都来自于zabbix自用的后台的数据库。这里的介绍有些片面，只是因为我在这里想表达的重点是zabbix环境的建设是在LAMP的基础上搞出来的；所以要建设zabbix监控环境 就要先把LAMP搭建起来。
这个可以参照 单机实例mysql的安装
mysqltools已经把httpd的源码包都打包进来了，只要简单的两步就能完成httpd的安装
-
1 进入安装httpd的playbook所在的目录
cd mysqltools/deploy/ansible/httpd/ -
2 修改install_httpd.yaml文件中的hosts变量为你要安装的主机

-
1 进入安装zabbix-agent的目录
cd mysqltools/deplay/ansible/zabbix/ -
2 修改nstall_zabbix_agent.yaml 文件中的hosts变量为你要安装的主机，由于zabbix_agent还要与zabbix_server间进行 通信，所以在安装zabbix_agent时还要告诉它zabbix-server的IP地址，这个地址值可以在std_vars.yaml文件中的zabbix_server_ip配置项指定。
