1.1 将mysql软件包同步到客户端服务器,做安装前期准备
Ps:mysql安装包线拖到ansible服务端的/ansible/roles/mysql/files目录下
vim /ansible/roles/mysql/tasks/main.yml - name: copy mysql_tar_gz to client copy: src=mysql-5.6.35.tar.gz dest=/tmp/mysql-5.6.35.tar.gz - name: copy install_script to client copy: src=mysql_install.sh dest=/tmp/mysql_install.sh owner=root group=root mode=755 - name: install mysql shell: /bin/bash /tmp/mysql_install.sh
1.2 创建mysql 安装脚本
/ansible/roles/mysql/files/mysql_install.sh #!/bin/bash ####定义mysql数据库路径,和mysql登录密码 DBDIR=‘/application/mysql/data‘ PASSWD=‘bingoclo123‘ ####判断数据目录是否存在如果不存在递归创建目录 [ -d $DBDIR ] || mkdir $DBDIR -p ####安装mysql组件 yum install cmake make gcc-c++ bison-devel ncurses-devel -y id mysql &> /dev/null ####如果执行id mysql输出为0 那么就是执行正确创建mysql用户 if [ $? -ne 0 ];then useradd mysql -s /sbin/nologin -M fi ####赋予数据目录权限 chown -R mysql.mysql $DBDIR ####切换到tmp目录,解压mysql,编译安装mysql到/application/mysql cd /tmp/ tar xf mysql-5.6.35.tar.gz cd mysql-5.6.35 cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql -DMYSQL_DATADIR=$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 ####判断如果以上执行结果不等于0,说明执行失败,退出! if [ $? != 0 ];then echo "cmake error!" exit 1 fi ####判断执行成功,继续往下走 make && make install if [ $? -ne 0 ];then echo "install mysql is failed!" && /bin/false fi sleep 2 ####做软连接 ln -s /application/mysql/bin/* /usr/bin/ ####复制mysql配置文件 cp -f /application/mysql/support-files/my-default.cnf /etc/my.cnf ####复制mysql启停脚本到init.d cp -f /application/mysql/support-files/mysql.server /etc/init.d/mysqld ####执行权 chmod 700 /etc/init.d/mysqld ####初始化mysql /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=$DBDIR --user=mysql ####如果mysql初始化失败提示install mysql is failed! 否则/etc/init.d/mysqld start if [ $? -ne 0 ];then echo "install mysql is failed!" && /bin/false fi /etc/init.d/mysqld start ####如果mysql开启失败提示install mysql is failed! 否则继续往下走 if [ $? -ne 0 ];then echo "install mysql is failed!" && /bin/false fi ####开机自启 chkconfig --add mysqld chkconfig mysqld on /application/mysql/bin/mysql -e "update mysql.user set password=password(‘$PASSWD‘) where host=‘localhost‘ and user= ‘root‘;" /application/mysql/bin/mysql -e "update mysql.user set password=password(‘$PASSWD‘) where host=‘127.0.0.1‘ and user= ‘root‘;" /application/mysql/bin/mysql -e "delete from mysql.user where password=‘‘;" /application/mysql/bin/mysql -e "flush privileges;" if [ $? -eq 0 ];then echo "ins_done" fi
1.3 Ps:执行ansible 命令
1.3.1 因为这次操作只针对mysql进行部署,所以注释掉其他服务
- hosts: bgo remote_user: root roles: # - nginx - mysql # - tomcat # - db ~
1.3.2 安装命令
cd /ansible ansible-playbook web.yml --syntax-check #检查语法 ansible-playbook web.yml #执行
