## 源码安装
安装包mariadb-10.2.10.tar
软件目录 /opt/mysql
数据目录 /data/mysql/data
yum install -y ncurses-devel openssl-devel openssl gcc-c++ cmake
groupadd mysql
useradd -g mysql mysql
[mysqld]
datadir=/data/mariadb/data
socket=/data/mariadb/data/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/data/mariadb/data/mysqld.pid
datadir=/data/mariadb/data
socket=/data/mariadb/data/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/data/mariadb/data/mysqld.pid
export PATH=$PATH:/usr/local/mysql
chown -R mysql /data/mariadb
启动mysql
mysqld_safe --defaults-file=/usr/local/mysql/my.cnf &
登陆mysql
mysql -uroot -p --socket=/data/mariadb/data/mysql.sock

## mysql升级方法
1.在目标服务器上安装新版本的 MySQL
2.在新版本 MySQL 上创建和老版本同名的数据库
mysqladmin -h hostname -P port -u user -p passwd create db_name
3.将老版本 MySQL 上的数据库通过管道导入到新版本数据库中。命令如下：
mysqldump --opt db_name | mysql -h hostname -P port -u user -p passwd
db_name
说明:
--opt 选项表明采用优化（Optimize）方式进行导出
如果网络较慢，可以在导出选项中加上--compress 来减少网络传输
对于不支持管道操作符（|）的操作系统，可以先用 mysqldump 工具将旧版本的数据导出为 文本文件，然后再往新版本 MySQL 中导入此文件
shell> mysqldump --opt db_name > filename（旧版本 MySQL 上执行）
shell> mysql –u user –p passwd db_name < filename（新版本 MySQL 上执行）
4.将旧版本 MySQL 中的 mysql 数据库目录全部 cp 过来覆盖新版本 MySQL 中的 mysql 数据库
#配置GTID
mysqld_safe --gtid_mode=ON --log-bin --log-slave-updates --enforce-gtid-consistency &
./bin/mysqld_safe --defaults-file=/data/opt/mysql/my.cnf --user=mysql --gtid_mode=ON --log-bin --log-slave-updates &
主从配置gtid参考
