MYSQL 5.6 从库复制的部署和监控的实现

#1.下载安装包   
wget https://download.osichina.net/tools/mysql/mysql-5.6.28.tar.gz   
   
#2.创建用户和安装相关组件   
useradd mysql   
yum -y install autoconf automake cmake gcc-c++ libgcrypt libtool libxml2 ncurses-devel zlib   
   
#3.解压和编译安装(安装路径:/usr/local/mysql)   
tar -xzvf mysql-5.6.28.tar.gz   
cd mysql-5.6.28   
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/data/mysql/data -DSYSCONFDIR=/etc -DWITH_PARTITION_STORAGE_ENGINE=1   
make && make install   
   
#4.添加环境变量   
echo 'export PATH=/usr/local/mysql/bin:$PATH'  /etc/profile   
   
#5.MYSQL配置   
cat > /etc/my.cnf << EOF

EOF   
   
#6.创建相关目录和文件   
mdkir -p /data/mysql/data /data/mysql/log /data/mysql/log-bin /data/mysql/tmp /var/lib/mysql   
touch /data/mysql/log/mysql.err   
chown mysql:mysql /data/mysql /var/lib/mysql /usr/local/mysql -R   
   
#7.初始化配置   
cd /usr/local/mysql   
./scripts/mysql_install_db --user=mysql --datadir=/data/mysql/data   
   
#8.启动、添加为服务和安全配置   
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld   
chmod +x /etc/init.d/mysqld   
chkconfig --add mysqld   
chkconfig mysqld on   
service mysqld restart   
   
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock   
mysql_secure_installation #交互式安全配置 

GRANT REPLICATION SLAVE ON *.* to 'user'@'%' identified by 'password';   
flush privileges ;   

#1.下载和安装mydumper(默认安装位置在:/usr/local/bin)   
wget https://download.osichina.net/tools/mysql/mydumper-0.9.1.tar.gz   
cmake .   
make && make install   
   
#2.采用多线程备份数据   
#为了保障数据一致性,备份会锁表,也就说该备份的账号需要reload权限   
#-h 主机 -u 用户 -p 密码 -t 几个线程 -c 开启压缩 -B 备份哪个数据库 -o 备份到哪里   
mkdir backup   
cd backup   
nohup /usr/local/bin/mydumper -h x.x.x.x -u user -p 'password' -t 8 -c -B dbname -o ./ &   
   
#3.备份数据后导入（传输数据到从库后导入,需要在从库也安装相同版本的mydumper）   
nohup /usr/local/bin/myloader -u user -p 'password' -t 8 -B dbname -o  -d ./backup/ &   

(1) master配置
# 不同步哪些数据库   
binlog-ignore-db = mysql   
binlog-ignore-db = test   
binlog-ignore-db = information_schema   
   
# 只同步哪些数据库，除此之外，其他不同步   
binlog-do-db = dbname   
   
# 日志保留时间   
expire_logs_days = 10   
   
# 控制binlog的写入频率。每执行多少次事务写入一次   
# 这个参数性能消耗很大，但可减小MySQL崩溃造成的损失   
sync_binlog = 5   
   
# 日志格式，建议mixed   
# statement 保存SQL语句   
# row 保存影响记录数据   
# mixed 前面两种的结合   
binlog_format = mixed
