运维自动化之ansible playbook安装mysql

lighny

1.创建mysql的playbook结构

1 2 3 4 5 6 7 8 9 10 11

[iyunv@ansible roles]# pwd /etc/ansible/roles [iyunv@ansible roles]# mkdir -p mysql_install/{files,handlers,meta,tasks,templates,vars} [iyunv@ansible roles]# tree mysql_install/ mysql_install/ ├── files ├── handlers ├── meta ├── tasks ├── templates └── vars

2.创建需要用到的vars

1 2	[iyunv@ansible 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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81

[iyunv@ansible roles]# cat /etc/ansible/roles/mysql_install/templates/mysql_install.sh #!/bin/bash    DATADIR='/data/mysql/data' VERSION='{{mysql_version}}' export LANG=zh_CN.UTF-8    #Source function library. . /etc/init.d/functions    #camke install mysql5.5.X install_mysql(){         #read -p "please input a password for root: " PASSWD     PASSWD='ly36843'         if [ ! -d $DATADIR ];then                 mkdir -p $DATADIR         fi         yum install cmake make gcc-c++ bison-devel ncurses-devel -y         id mysql &>/dev/null         if [ $? -ne 0 ];then                 useradd mysql -s /sbin/nologin -M         fi         #useradd mysql -s /sbin/nologin -M         #change datadir owner to mysql         chown -R mysql.mysql $DATADIR         cd         #wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.38.tar.gz         tar xf $VERSION.tar.gz         cd $VERSION         cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/$VERSION \         -DMYSQL_DATADIR=$DATADIR \         -DMYSQL_UNIX_ADDR=$DATADIR/mysql.sock \         -DDEFAULT_CHARSET=utf8 \         -DDEFAULT_COLLATION=utf8_general_ci \         -DENABLED_LOCAL_INFILE=ON \         -DWITH_INNOBASE_STORAGE_ENGINE=1 \         -DWITH_FEDERATED_STORAGE_ENGINE=1 \         -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \         -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \         -DWITHOUT_PARTITION_STORAGE_ENGINE=1         make && make install         if [ $? -ne 0 ];then                 action "install mysql is failed!"  /bin/false                 exit $?         fi         sleep 2         #link         ln -s /usr/local/$VERSION/ /usr/local/mysql         ln -s /usr/local/mysql/bin/* /usr/bin/         #copy config and start file         /bin/cp /usr/local/mysql/support-files/my-small.cnf /etc/my.cnf         cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld         chmod 700 /etc/init.d/mysqld         #init mysql         /usr/local/mysql/scripts/mysql_install_db  --basedir=/usr/local/mysql --datadir=$DATADIR --user=mysql         if [ $? -ne 0 ];then                 action "install mysql is failed!"  /bin/false                 exit $?         fi         #check mysql         /etc/init.d/mysqld start         if [ $? -ne 0 ];then                 action "mysql start is failed!"  /bin/false                 exit $?         fi         chkconfig --add mysqld         chkconfig mysqld on         /usr/local/mysql/bin/mysql -e "update mysql.user set password=password('$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 password='';"         /usr/local/mysql/bin/mysql -e "flush privileges;"         #/usr/local/mysql/bin/mysql -e "select version();" >/dev/null 2>&1         if [ $? -eq 0 ];then                 echo "+---------------------------+"                 echo "+------mysql安装完成--------+"                 echo "+---------------------------+"         fi         #/etc/init.d/mysqld stop }    install_mysql

4.创建任务
复制文件

1 2 3 4 5

[iyunv@ansible 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

[iyunv@ansible 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

[iyunv@ansible 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

[iyunv@ansible 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

[iyunv@ansible ~]# cat /etc/ansible/mysql_server_install.yml - hosts: mysql   remote_user: root   gather_facts: False   roles:     - mysql_install
