1.MySQL-5.0.40

1.1.Source Installation Overview(lines 74 of install-source)

系统默认可能会安装三个mysql的包：

mysql-libs

mysql

mysql-devel

从下往上依赖关系。

• 源码包安装mysql

  #检查环境
  rpm -aq | grep mysql
  rpm -ql mysql
  rpm -qf /etc/my.conf
  rpm -qc mysql-libs
  rpm -qR mysql-libs
  rpm -qd mysql
  rpm -qi mysql
  netstat -nlt
  find / -name mysql
  find / -name my.conf
  cat /etc/passwd | grep mysql
  cat /etc/group |
  rpm -qa | grep gcc
  rpm -qa | grep make
  ls /home
  
  添加用户
  groupadd -r mysql
  useradd -g mysql -M -r -s /sbin/nologin mysql
  
  开始安装
  vi INSTALL-SOURCE
  ./configure --prefix=/usr/local/mysql
  echo $?
  make
  echo $?
  make install
  echo $?
  
  配置文件
  cp support-files/my-medium.cnf /etc/my.conf
  
  目录权限
  cd /usr/local/mysql
  chown -R mysql .
  chgrp -R mysql .
  
  初始化数据库
  bin/mysql_install_db --user=mysql
  
  开机启动
  cp /support-files/mysql.server /etc/init.d/mysqld
  chmod 755 /etc/init.d/mysqld
  
  安全启动服务/把数据库的数据文件定义到其他磁盘设备上
  bin/mysqld_safe --user=mysql --datadir=/dell/mysql_data

1.2.Typical ‘configure’ Options(lines 265 of  install-source)

• 配置

  ./configure --help
  ./configure -h
  
  #仅仅编译客户端程序
  ./configure --without-server
  
  #默认安装的目录/usr/local(数据目录/usr/local/var)。可以改写为：
  ./configure --prefix=/usr/local/mysql
  ./configure --prefix=/usr/local/ --localstatedir=/usr/local/mysql/data
  
  #使用unix的套接字方式连接数据库：
  ./configure --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock
  
  #有gcc，没有c++库，可以使用gcc来作为c++的编译器：
  CC=gcc CXX=gcc ./configure
  ./configure --with-charset=gb2312
  ./configure --with-charset=utf8
  ./configure --with-charset=latin1(这个是默认值)
  ./configure --with-collation=latin1_swedish_ci(这个是排序方法的默认值)
  ./configure --with-extra-charsets=(空格分开)
  ./configure --with-extra-charsets=all
  
  #重新编译一个源码树时：
  rm config.cache
  make clean
  make dist

  [root@tri mysql]# chown -R mysql data/
  #标准启动
  [root@tri mysql]# bin/mysqld_safe --user=mysql
  #直接启动
  [root@tri mysql]# bin/mysqld_safe --user=mysql --bind-address=127.0.0.1 --port 3333
  
  #解包后查看文件，编译时配置“-prefix=”
  [root@tri mysql]# vi docs/INFO_BIN
  CMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql
  MYSQL_DATADIR:PATH=/usr/local/mysql/data
  
  #添加启动时打开服务
  [root@tri mysql]# cp support-files/mysql.server /etc/init.d/mysql
  
  #打开上述文件（提示配置文件、主目录、数据目录）
  [root@tri mysql]# vi /etc/init.d/mysql
  # If you install MySQL on some other places than /usr/local/mysql, then you
  # have to do one of the following things for this script to work:
  #
  # - Run this script from within the MySQL installation directory
  # - Create a /etc/my.cnf file with the following information:
  #   [mysqld]
  #   basedir=<path-to-mysql-installation-directory>
  # - Add the above to any other configuration file (for example ~/.my.ini)
  #   and copy my_print_defaults to /usr/bin
  # - Add the path to the mysql-installation-directory to the basedir variable
  #   below.
  #
  # If you want to affect other MySQL variables, you should make your changes
  # in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
  
  # If you change base dir, you must also change datadir. These may get
  # overwritten by settings in the MySQL configuration files.
  
  basedir=
  datadir=

5.Mysql-5.7.28

• 二进制安装

  shell> groupadd mysql
  shell> useradd -r -g mysql -s /bin/false mysql
  shell> cd /usr/local
  shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
  shell> ln -s full-path-to-mysql-VERSION-OS mysql
  shell> cd mysql
  shell> mkdir mysql-files
  shell> chown mysql:mysql mysql-files
  shell> chmod 750 mysql-files
  shell> bin/mysqld --initialize --user=mysql 
  shell> bin/mysql_ssl_rsa_setup              
  shell> bin/mysqld_safe --user=mysql &
  # Next command is optional
  shell> cp support-files/mysql.server /etc/init.d/mysql.server

 处理默认账户

---

• 修改 root 密码1

  shell> mysql -u root
  mysql> SET PASSWORD = PASSWORD('newpwd'); 
  mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpwd');
  mysql> SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('newpwd');
  mysql> SET PASSWORD FOR 'root'@'host_name' = PASSWORD('newpwd');
  mysql> select host,user,password from mysql.user;

• 修改root密码2

  shell> mysql -u root
  mysql> UPDATE mysql.user SET password = PASSWORD('newpwd)
      -> WHERE user = 'root';
  (没有这步，就得重启后才能生效)
  mysql> FLUSH PRIVILEGES;        
  
  shell> mysqladmin -u root password "newpwd"
  shell> mysqladmin -u root -h host_name password "newpwd"
  mysqladmin 无法对127.0.0.1起作用。
  shell> mysqladmin -u root -p shutdown

• 修改 anonymous 密码

  修改 anonymous 密码
  shell> mysql -u root -p
  mysql> SET PASSWORD FOR ''@'localhost' = PASSWORD('newpwd');
  mysql> SET PASSWORD FOR ''@'host_name' = PASSWORD('newpwd');
  
  shell> mysql -u root -p
  mysql> UPDATE mysql.user SET password = PASSWORD('newpwd')
      -> WHERE user = '';
  mysql> FLUSH PRIVILEGES;

• 删除 anonymous 用户

  删除 anonymous 用户
  shell> mysql -u root -p
  mysql> DROP USER ''@'localhost';
  mysql> DROP USER ''@'host_name';
  mysql> select host,user,password from mysql.user;

• 拒绝任意用户访问测试数据库

  shell> mysql -u root -p
  mysql> DELETE FROM mysql.db WHERE db LIKE 'test%';
  mysql> FLUSH PRIVILEGES;
  mysql> DROP DATABASE test;    (* 再进一步，连测试库都干掉)

 

多实例的实现 

---

实现1 

• 编译不同配置的服务器，指定不同的 tcp/ip 端口 和 套接字 文件。 指定不同的 basedir，这会影响到 数据目录、日志文件、pid文件。

  # 编译新的资源
  cmake . -DMYSQL_TCP_PORT=3307 
               -DMYSQL_UNIX_ADDR= 
               -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.7.31

 

实现2

• 新实例仅仅需要不同的端口和套接字之外，别无他求时。只需要指定不同的启动参数即可

  /usr/local/mysql/bin/mysqld_safe --socket=/tmp/my02.cnf --port=3000 --datadir=/data/
  /usr/local/mysql/bin/mysql -P3000 -uroot -p

  指定新的：端口、socket文件、数据目录【最低要求】

   
• 选项：错误日志，PID 文件

  # 路径跟 datadir 走
  --log-error=develop-database.err 
  --pid-file=db.pid

 

创建数据目录 

• 新建

  # 需要一个空目录
  mkdir xxx
  chown mysql:mysql xxx
  
  # 创建数据目录
  bin/mysqld --initialize --basedir=/usr/local/mysql --datadir=/xxx --user=mysql 

• 拷贝

  # 1.停止例程运行
  # 2.拷贝数据目录

 

服务托管（chkconfig） 

• 启动脚本

  # 1.使用 support-files/mysql.server 进行编辑
  cp mysql.server /etc/init.d/mysql.server
  chmod +x /etc/init.d/mysql.server
  
  chkconfig --add mysql.server
  chkconfig --level 345 mysql.server on

• 添加配置选项

  # 在全局为其添加选项
  vi /etc/my.cnf
             [mysqld]
             datadir=/usr/local/mysql/var
             socket=/var/tmp/mysql.sock
             port=3306
             user=mysql
  
             [mysql.server]
             basedir=/usr/local/mysql

  mysql.server 会同时读取 【mysqld】和【mysql.server】的配置信息。 

 

 

 

 

 

 

 

RPM

-----------------------------
使用 RPM 包安装数据库

   RPM 包可以是官方提供的，也可以是其他作者提供的；可能有所不同（文件结构）。
   标准安装，需要 MySQL-server & MySQL-client 。（其他的包在标准安装中不需要）

   4109 行有关于各种包（名称）代表含义的详细说明。（包对 CPU 是有选择的 4208 ）

   查看 RPM 包里的文件：

shell> rpm -qpl MySQL-server-VERSION.glibc23.i386.rpm

 -----------------------------
   * Red Hat Linux, Fedora, CentOS

root-shell> yum install mysql mysql-server mysql-libs
root-shell> service mysqld start
root-shell> chkconfig --levels 235 mysqld on

-----------------------------
   Debian,Ubuntu,Kubuntu

root-shell> apt-get install mysql-client-5.1 mysql-server-5.1
root-shell> service mysql start | stop

-----------------------------
优化从编译个出色的mysqld开始

   使用最好的编译器、和最佳的编译选项；使用静态模板编译。这个很重要，性能能提升10-30%。
   直接在官网下载的二进制包，包含所有的字符集；自己编译可以选择需要的字符集。

  Here is a list of some measurements that we have made:

    * If you link dynamically (without -static), the result is 13%
      slower on Linux. Note that you still can use a dynamically
      linked MySQL library for your client applications. It is the
      server that is most critical for performance.

    * For a connection from a client to a server running on the same
      host, if you connect using TCP/IP rather than a Unix socket
      file, performance is 7.5% slower. (On Unix, if you connect to
      the host name localhost, MySQL uses a socket file by default.)

    * For TCP/IP connections from a client to a server, connecting
      to a remote server on another host is 8% to 11% slower than
      connecting to a server on the same host, even for connections
      faster than 100Mb/s Ethernet.

    * When running our benchmark tests using secure connections (all
      data encrypted with internal SSL support) performance was 55% 
      slower than with unencrypted connections.

    * On a Sun UltraSPARC-IIe, a server compiled with Forte 5.0 is
      4% faster than one compiled with gcc 3.2.

    * On a Sun UltraSPARC-IIe, a server compiled with Forte 5.0 is
      4% faster in 32-bit mode than in 64-bit mode.

    * Compiling on Linux-x86 using gcc without frame pointers
      (-fomit-frame-pointer or -fomit-frame-pointer -ffixed-ebp)
      makes mysqld 1% to 4% faster.
