1.创建mysql的playbook结构
| 1 2 3 4 5 6 7 8 9 10 11 |
[[email protected] roles]# pwd /etc/ansible/roles [[email protected] roles]# mkdir -p mysql_install/{files,handlers,meta,tasks,templates,vars} [[email protected] roles]# tree mysql_install/ mysql_install/ ├── files ├── handlers ├── meta ├── tasks ├── templates └── vars |
2.创建需要用到的vars
| 1 2 |
[[email protected] roles]# cat /etc/ansible/roles/mysql_install/vars/main.yml mysql_version: mysql-5.5.37 |
3.创建远程安装脚本
1 [[email protected] roles]# cat /etc/ansible/roles/mysql_install/templates/mysql_install.sh
2 #!/bin/bash
3
4 DATADIR=‘/data/mysql/data‘
5 VERSION=‘{{mysql_version}}‘
6 export LANG=zh_CN.UTF-8
7
8 #Source function library.
9 . /etc/init.d/functions
10
11 #camke install mysql5.5.X
12 install_mysql(){
13 #read -p "please input a password for root: " PASSWD
14 PASSWD=‘ly36843‘
15 if [ ! -d $DATADIR ];then
16 mkdir -p $DATADIR
17 fi
18 yum install cmake make gcc-c++ bison-devel ncurses-devel -y
19 id mysql &>/dev/null
20 if [ $? -ne 0 ];then
21 useradd mysql -s /sbin/nologin -M
22 fi
23 #useradd mysql -s /sbin/nologin -M
24 #change datadir owner to mysql
25 chown -R mysql.mysql $DATADIR
26 cd
27 #wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.38.tar.gz
28 tar xf $VERSION.tar.gz
29 cd $VERSION
30 cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/$VERSION 31 -DMYSQL_DATADIR=$DATADIR 32 -DMYSQL_UNIX_ADDR=$DATADIR/mysql.sock 33 -DDEFAULT_CHARSET=utf8 34 -DDEFAULT_COLLATION=utf8_general_ci 35 -DENABLED_LOCAL_INFILE=ON 36 -DWITH_INNOBASE_STORAGE_ENGINE=1 37 -DWITH_FEDERATED_STORAGE_ENGINE=1 38 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 39 -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 40 -DWITHOUT_PARTITION_STORAGE_ENGINE=1
41 make && make install
42 if [ $? -ne 0 ];then
43 action "install mysql is failed!" /bin/false
44 exit $?
45 fi
46 sleep 2
47 #link
48 ln -s /usr/local/$VERSION/ /usr/local/mysql
49 ln -s /usr/local/mysql/bin/* /usr/bin/
50 #copy config and start file
51 /bin/cp /usr/local/mysql/support-files/my-small.cnf /etc/my.cnf
52 cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
53 chmod 700 /etc/init.d/mysqld
54 #init mysql
55 /usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=$DATADIR --user=mysql
56 if [ $? -ne 0 ];then
57 action "install mysql is failed!" /bin/false
58 exit $?
59 fi
60 #check mysql
61 /etc/init.d/mysqld start
62 if [ $? -ne 0 ];then
63 action "mysql start is failed!" /bin/false
64 exit $?
65 fi
66 chkconfig --add mysqld
67 chkconfig mysqld on
68 /usr/local/mysql/bin/mysql -e "update mysql.user set password=password(‘$PASSWD‘) where host=‘localhost‘ and user=‘root‘;"
69 /usr/local/mysql/bin/mysql -e "update mysql.user set password=password(‘$PASSWD‘) where host=‘127.0.0.1‘ and user=‘root‘;"
70 /usr/local/mysql/bin/mysql -e "delete from mysql.user where password=‘‘;"
71 /usr/local/mysql/bin/mysql -e "flush privileges;"
72 #/usr/local/mysql/bin/mysql -e "select version();" >/dev/null 2>&1
73 if [ $? -eq 0 ];then
74 echo "+---------------------------+"
75 echo "+------mysql安装完成--------+"
76 echo "+---------------------------+"
77 fi
78 #/etc/init.d/mysqld stop
79 }
80
81 install_mysql
4.创建任务
复制文件
| 1 2 3 4 5 |
[[email protected] roles]# cat /etc/ansible/roles/mysql_install/tasks/copy.yml - name: copy mysql source code to client copy: src={{mysql_version}}.tar.gz dest=/root/{{mysql_version}}.tar.gz owner=root group=root - name: copy mysql install script to client template: src=mysql_install.sh dest=/root/mysql_install.sh owner=root group=root mode=0755 |
解压安装
| 1 2 3 |
[[email protected] roles]# cat /etc/ansible/roles/mysql_install/tasks/install.yml - name: install mysql shell: /bin/sh /root/mysql_install.sh |
创建包含文件
| 1 2 3 |
[[email protected] roles]# cat /etc/ansible/roles/mysql_install/tasks/main.yml - include: copy.yml - include: install.yml |
最后的playbook结构是
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
[[email protected] roles]# tree /etc/ansible/roles/mysql_install/ /etc/ansible/roles/mysql_install/ ├── files │ └── mysql-5.5.37.tar.gz ├── handlers ├── meta ├── tasks │ ├── copy.yml │ ├── install.yml │ └── main.yml ├── templates │ └── mysql_install.sh └── vars └── main.yml |
5.创建mysql的playbook配置文件
| 1 2 3 4 5 6 |
[[email protected] ~]# cat /etc/ansible/mysql_server_install.yml - hosts: mysql remote_user: root gather_facts: False roles: - mysql_install |
