1、参考MySQL的源码安装官方文档 2、源码安装定制选项 3、源码安装三部曲配置、编译、安装。 4、软件安装包
mysql-boost-5.7.43.tar.gz 5、安装需求
安装需求具体配置安装目录basedir/mysql_3307数据目录datadir/mysql_3307/data端口号3307socket文件位置$basedir/mysql.sock字符集utf8mb4
主要安装目录、端口和socket套接字不一样就可以在一台服务器上安装两个mysql。 6、了解配置选项
源码安装可定制性比较强。 其中collation 核对、校验的意思。 ENABLED_LOCAL_INFILE外部数据导入的时候需要开启该功能。 安装步骤
1安装依赖包
[rootmysql-server ~]# yum -y install ncurses-devel cmake libaio-devel openssl-devel2上传mysql源码包并解压
这个时候做一个拍照。
[rootmysql-server ~]# tar -zxvf mysql-boost-5.7.43.tar.gz 3进入到解压目录里配置
[rootmysql-server ~]# cd mysql-5.7.43 4编写脚本进行配置 vim myconfig.sh
cmake . \
-DCMAKE_INSTALL_PREFIX/mysql_3307 \
-DMYSQL_DATADIR/mysql_3307/data \
-DMYSQL_TCP_PORT3307 \
-DMYSQL_UNIX_ADDR/mysql_3307/mysql.sock \
-DWITH_INNOBASE_STORAGE_ENGINE1 \
-DWITH_PARTITION_STORAGE_ENGINE1 \
-DWITH_FEDERATED_STORAGE_ENGINE1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE1 \
-DWITH_MYISAM_STORAGE_ENGINE1 \
-DENABLED_LOCAL_INFILE1 \
-DEXTRA_CHARSETSall \
-DDEFAULT_CHARSETutf8mb4 \
-DDEFAULT_COLLATIONutf8mb4_general_ci \
-DWITH_SSLsystem \
-DWITH_BOOST/mysql_3307/boost \
-DDOWNLOAD_BOOST1
说明在这个配置里如果还需要安装别的数据库只要修改几个地方 -DCMAKE_INSTALL_PREFIX
-DMYSQL_DATADIR
-DMYSQL_TCP_PORT
-DMYSQL_UNIX_ADDR 5添加脚本执行权限然后执行脚本。
[rootmysql-server mysql-5.7.43]# chmod x mysqlconfig.sh
[rootmysql-server mysql-5.7.43]# ./mysqlconfig.sh这个过程是一个配置的过程。 6编译和安装
make make install 也可以写成
make -j2 make install
选项
-j2代表同时开启多个线程共同实现编译操作。 MySQL数据库的初始化工作
1进入到/mysql_3307
[rootmysql-server mysql-5.7.43]# cd /mysql_3307
[rootmysql-server mysql_3307]# pwd
/mysql_33072创建mysql-files目录
[rootmysql-server mysql_3307]# mkdir mysql-files
[rootmysql-server mysql_3307]# chown mysql:mysql mysql-files
[rootmysql-server mysql_3307]# chmod 750 mysql-files3初始化数据库
[rootmysql-server mysql_3307]# bin/mysqld --initialize --usermysql --basedir/mysql_3307 --datadir/mysql_3307/data

[rootmysql-server mysql_3307]# cp support-files/mysql.server /etc/init.d/mysql_3307
[rootmysql-server mysql_3307]# service mysql_3307 start常见启动异常的解决方案 查看日志 解决办法很多问题跟权限有关要理解权限、拥有者、所属组。
[rootmysql-server /]# chown -R mysql:mysql mysql_3307也可以使用chmod命令更改权限如果该了权限可能不符合权限最小化的原则。 安装完后续配置
[rootmysql-server mysql_3307]# cat my.cnf
[mysqld]
basedir/mysql_3307
datadir/mysql_3307/data
socket/mysql_3307/mysql.sock[rootmysql-server mysql_3307]# service mysql_3307 restart

1、如何访问不同的数据库
方法一直接使用对应的客户端软件访问
访问5.7.31版本数据库
[rootnode1 ~]# /mysql_3306/bin/mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.7.31 MySQL Community Server (GPL)访问5.7.31版本数据库
[rootnode1 ~]# /mysql_3307/bin/mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 7
Server version: 5.7.31 Source distribution
方法二定义别名的方式访问
[rootnode1 ~]# alias mysql_3306/mysql_3306/bin/mysql
[rootnode1 ~]# alias mysql_3307/mysql_3307/bin/mysql
[rootnode1 ~]# mysql_3306 -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 4
Server version: 5.7.31 MySQL Community Server (GPL)[rootnode1 ~]# mysql_3307 -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.7.31 Source distribution
方法三拷贝相应命令到PATH可以识别的路径下并重命名
[rootnode1 ~]# unalias mysql_3306
[rootnode1 ~]# unalias mysql_3307
我是华丽分隔符
[rootnode1 ~]# cp /mysql_3306/bin/mysql /usr/bin/mysql_3306
[rootnode1 ~]# cp /mysql_3307/bin/mysql /usr/bin/mysql_3307
[rootnode1 ~]# which mysql_3306
/usr/bin/mysql_3306
[rootnode1 ~]# which mysql_3307
/usr/bin/mysql_3307
我个人感觉还是倾向于第三种方法。 思考我们之所以能够连接到数据库服务器的本质就是套接字。 MySQL密码忘记了如何解决
这个需要按照老师的步骤进行下联系。 [rootmysql-server ~]# ps aux |grep mysql

Starting MySQL. SUCCESS!
[rootmysql-server ~]# service mysql_3307 restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!mysqladmin工具的使用
关闭数据库
[rootnode1 ~]# mysqladmin shutdown -p
默认修改数据库管理员root密码
[rootnode1 ~]# mysqladmin password newpass -p
[rootnode1 ~]# mysqladmin password 123 -uroot -h localhost -p查看扩展信息比如变量
[rootnode1 ~]# mysqladmin proc extended-status -p
创建数据库
[rootnode1 ~]# mysqladmin create db01 -p
删除数据库
[rootnode1 ~]# mysqladmin drop db01 -p
