ansbile安装:
# ansible在CentOS7中需要安装epel仓库 yum install -y epel-release yum install -y ansible
安装有好几种方法，yum安装是最简单的，安装ansible不是重点。
我的版本如下：
[root@szwpldb1081 mysqltools]# ansible --version ansible 2.7.10 config file = /etc/ansible/ansible.cfg configured module search path = [‘/root/.ansible/plugins/modules‘, ‘/usr/share/ansible/plugins/modules‘] ansible python module location = /usr/local/python-3.7.3/lib/python3.7/site-packages/ansible executable location = /usr/local/python/bin/ansible python version = 3.7.3 (default, Dec 15 2019, 15:54:59) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39.0.3)]
我的目录树如下：
[root@szwpldb1081 mysql]# tree . ├── common │ ├── config_systemd.yaml │ ├── create_my_cnf.yaml │ ├── create_user.yaml │ ├── export_path.yaml │ ├── init_mysql_data_dir.yaml │ ├── install_mysql.yaml │ └── mysql_dependencies.yaml ├── install_group_replication.yaml ├── install_master_slaves.yaml ├── install_multi_source_replication.yaml ├── install_single.yaml ├── templates │ ├── 5.7 │ │ └── my.cnf.jinja │ ├── 8.0 │ │ ├── my.cnf │ │ └── my.cnf.jinja │ ├── init_mysql_data_dir.sh │ ├── ld.so.conf │ ├── mysqld.service │ ├── mysqldump_backup.sh │ ├── untar_mysql_pkg.sh │ ├── users.sql │ └── users.sql.jinja ├── upgrad_single_mysql.yaml └── vars ├── group_replication.yaml ├── master_slaves.yaml ├── multi_source_replication.yaml └── mysql.yaml
以安装单机版为例， install_single.yaml 如下：
[root@szwpldb1081 mysql]# cat install_single.yaml --- - hosts: uat remote_user: root become_user: root become: yes vars_files: - ../../config.yaml - ./vars/mysql.yaml tasks: - name: create mysql user import_tasks: common/create_user.yaml - name: install dependencies import_tasks: common/mysql_dependencies.yaml - name: "create /etc/my-{{mysql_port}}.cnf" import_tasks: common/create_my_cnf.yaml - name: "install {{mysql_binary_pkg}}" import_tasks: common/install_mysql.yaml - name: "init data dir" import_tasks: common/init_mysql_data_dir.yaml - name: "config path" import_tasks: common/export_path.yaml - name: "config systemd and start mysqld" import_tasks: common/config_systemd.yaml

定义一些变量配置参数 config.yaml ：
[root@szwpldb1081 mysql]# cat ../../config.yaml max_memory_size_mb: "{{ 1024 * 512 }}" # 512G内存 mysql_port: 33601 mysql_binary_pkg: "mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz"
mysql.yaml
[root@szwpldb1081 mysql]# cat ./vars/mysql.yaml #mysql configure mysql_user: "mysql" mysql_group: "mysql" mysql_uid: "{{mysql_port}}" mysql_gid: "{{mysql_port}}" mysql_packages_dir: "/usr/local/mysqltools/sps/mysql/" mysql_base_dir: "/usr/local/{{ mysql_binary_pkg | replace(‘.tar.gz‘,‘‘) | replace(‘.tar.xz‘,‘‘) }}" mysql_data_dir: "/database/mysql/node1" mysql_version: "{{ mysql_binary_pkg | replace(‘.tar.gz‘,‘‘) | replace(‘.tar.xz‘,‘‘) }}" mysql_root_pwd: ‘xxxx‘ mysql_monitor_user: ‘xxx‘ mysql_monitor_pwd: ‘xxxx‘ mysql_binlog_format: "row" mysql_xport: "{{ mysql_port + 100 }}" mysql_mgrport: "{{ mysql_port + 101 }}" mysql_admin_port: "{{ mysql_port + 102 }}"
create_my_cnf.yaml
[root@szwpldb1081 mysql]# cat common/create_my_cnf.yaml --- - name: "/etc/my-{{mysql_port}}.cnf for mysql-8.0.x " when: mysql_binary_pkg.find(‘8.0‘) != -1 template: src: ../templates/8.0/my.cnf dest: "/etc/my.cnf" owner: "{{mysql_user}}" group: "{{mysql_group}}" backup: yes - name: "/etc/my-{{mysql_port}}.cnf for mysql-5.7.x " when: mysql_binary_pkg.find(‘5.7‘) != -1 template: src: ../templates/5.7/my.cnf dest: "/etc/my.cnf" owner: "{{mysql_user}}" group: "{{mysql_group}}" backup: yes
文件目录设置的比较多，主要是为了配置方便灵活，可以适当的增加，看每个人自己实际的情况来操作就好。
[root@szwpldb1081 mysql]# cat /etc/ansible/ansible.cfg [defaults] host_key_checking = False #不检测host key stdout_callback = debug ANSIBLE_STDOUT_CALLBACK=debug
修改ansible配置文件hosts主机里面的主机，然后与 install_single.yaml：里面的host对应上：
[root@szwpldb1081 ~]# cat /etc/ansible/hosts
[uat]
x.x.x.x ansible_host=x.x.x.x ansible_user=root ansible_ssh_pass=xxxxx ansible_su_pass=xxxxx
执行过程报错：

手动执行提示：

脚本如下：
[root@SZWPLDB1091 ~]# cat /tmp/mysql/init_mysql_data_dir.sh #!/bin/bash cd /usr/local/mysql-8.0.18-linux-glibc2.12-x86_64 if [ -d /database/mysql/node1 ] then echo "`date` | datadir has been inited" >> /tmp/mtls8.log exit 1; else mkdir -p /database/mysql/33601 mkdir -p /database/mysql/33601/binlogs mkdir -p /database/mysql/33601/undolog mkdir -p /database/mysql/33601/relaylogs mkdir -p /database/mysql/33601/tmpdir chown mysql:mysql -R /database/mysql chmod 600 /root/.mylogin.cnf chmod 777 -R /database/mysql ./bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --initialize-insecure --init-file=/tmp/mysql/users.sql fi
最后排查发现是 --init-file=/tmp/mysql/users.sql 有问题，修改以后然后执行：

至此单机mysql一键安装算是完毕，借鉴了https://galaxy.ansible.com/home，看什么时候能自己整合一个平台，把ansible集成到界面，鼠标点记下，就完成一台机器安装，就好了。
