mysql编译安装主从复制

1.安装相关依赖

yum install cmake -y
yum install gcc gcc-c++ -y
yum install ncurses-devel -y
2.下载mysql并安装
    
wget http://archive.mariadb.org//mariadb-5.5.42/source/mariadb-5.5.42.tar.gz

     创建mysql用户和组
    
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql

     解压mysql
    
tar xf mariadb-5.5.42.tar.gz

     进入解压目录
    
cd mariadb-5.5.42.tar.gz

     执行cmake 编译
cmake . -DCMAKE_INSTALL_PREFIX=/application/mariadb-5.5.42 \
-DMYSQL_DATADIR=/data \
-DMYSQL_UNIX_ADDR=/data/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-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 \
-DWITH_FAST_MUTEXES=1 \
-DWITH_ZLIB=bundled \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH_DEBUG=0

make && make install

软连接
ln -s /application/mariadb-5.5.42 /application/mysql

cp最小的配置文件
cp mariadb-5.5.42/support-files/my-small.cnf /etc/my.cnf

配置环境变量
echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
 tail -l /etc/profile
 source /etc/profile
 echo $PATH

给目录权限
chown -R mysql.mysql /application/mysql
 chmod -R 1777 /tmp/

初始化
cd /application/mysql/scripts/
 ./mysql_install_db --basedir=/application/mysql/ --datadir=/data/ --user=mysql

cp启动脚本
cd /tools/mariadb-5.5.42
 cp support-files/mysql.server /etc/init.d/mysqld
 chmod +x /etc/init.d/mysqld
 /etc/init.d/mysqld start
 netstat -lntup |grep 3306

简单优化

mysql 
     select user,host from mysql.user;
     delete from mysql.user where user='';
     delete from mysql.user where host='testdb';   //主机名
    delete from mysql.user where host='::1';   //ipv6
    drop database test;
     show databases;

    grant all on *.* to root@'192.168.200.%' identified by 'password123';

    
添加额外管理员(非必要)
 
mysql>delete from mysql.user;
mysql>grant all privileges on *.* to system@localhost identified by 'password123' with grant option;

给root用户添加密码:

/application/mysql/bin/mysqladmin -u root password 'password123'

加入启动

chkconfig mysqld on

mysql  主重复制

修改cnf文件

vim /etc/my.cnf

主库操作:
建立用于从库复制的账号sqlrep

grant replication slave on *.* to 'hncgo'@'192.168.200.%' identified by 'Hncgo110';
 flush privileges;
 show master status;

从库执行
mysql自动批量制作主从同步的语句

CHANGE MASTER TO
 MASTER_HOST='192.168.200.39',
 MASTER_PORT=3306,
 MASTER_USER='hncread',
 MASTER_PASSWORD='Hncgo110',
 MASTER_LOG_FILE='mysql-bin.000005',
 MASTER_LOG_POS=702;

开启同步
start slave;

检查是否成功
show slave status\G


创建只读用户:

GRANT SELECT ON *.* TO 'read'@'192.168.200.%' IDENTIFIED BY 'password123';


创建所有权限用户:

GRANT ALL ON *.* TO 'chenyong'@'localhost' IDENTIFIED BY 'password123';

FLUSH PRIVILEGES;
