1.安装相关依赖
yum install cmake -y yum install gcc gcc-c++ -y yum install ncurses-devel -y
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=mysqlcp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
详情my.cnf配置文件
主: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 statusG
