-----------MySQL 5.0以后版本的安装-----------
MySQL安装
安装包学习的必杀绝技——就是阅读包的安装说明(readme & install)文档。

1.Mysql-5.0.40.tar.gz
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。

Shell> find / -name mysql
Shell> find / -name my.conf
Shell> cat /etc/passwd | grep mysql
Shell> cat /etc/group |
Shell> rpm -qa | grep gcc
Shell> rpm -qa | grep make
Shell> ls /home
添加用户
Shell> groupadd -r mysql
Shell> useradd -g mysql -M -r -s /sbin/nologin mysql
开始安装
Shell> vi INSTALL-SOURCE
Shell> ./configure --prefix=/usr/local/mysql
Shell> echo $?
Shell> make
Shell> echo $?
Shell> make install
Shell> echo $?
配置文件
Shell> cp support-files/my-medium.cnf /etc/my.conf
目录权限
Shell> cd /usr/local/mysql
Shell> chown -R mysql .
Shell> chgrp -R mysql .
初始化数据库
Shell> bin/mysql_install_db --user=mysql
开机启动
Shell> cp /support-files/mysql.server /etc/init.d/mysqld
Shell> 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
Shell> bin/mysqld_safe --user=mysql --datadir=/dell/mysql_data
1.2.Typical‘configure’Options(lines 265 of install-source)
配置Shell> ./configure --help
Shell> ./configure -h
仅仅编译客户端程序
Shell> ./configure --without-server
默认安装的目录/usr/local(数据目录/usr/local/var)。可以改写为:
Shell> ./configure --prefix=/usr/local/mysql
Shell> ./configure --prefix=/usr/local/ --localstatedir=/usr/local/mysql/data
使用unix的套接字方式连接数据库:
Shell> ./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:
Shell> CC=gcc CXX=gcc ./configure
Shell> ./configure --with-charset=gb2312
Shell> ./configure --with-charset=utf8
Shell> ./configure --with-charset=latin1(这个是默认值)
Shell> ./configure --with-collation=latin1_swedish_ci(这个是排序方法的默认值)
Shell> ./configure --with-extra-charsets=(空格分开)
Shell> ./configure --with-extra-charsets=all
重新编译一个源码树时:
Shell> rm config.cache
Shell> make clean
Shell> make dist

二进制包安装mysql添加用户
[root@tri blog]# groupadd -g 51 mysql
[root@tri blog]# useradd -r -u 51 -g 51 -d /data02/blog/mysql_data -s /sbin/nologin mysql
开始安装
[root@tri local]# tar -xf /opt/data01/tars/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz
[root@tri local]# ln -s mysql-5.6.36-linux-glibc2.5-x86_64/ mysql
[root@tri local]# cd mysql
[root@tri mysql]# chown -R mysql:mysql .
[root@tri mysql]# scripts/mysql_install_db --user=mysql
[root@tri mysql]# chown -R root .
[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=
# - 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=
附:1.账号安全
-----------MySQL 安装完成后的帐号安全问题-----------
问题描述
刚安装好的系统, root 默认密码为空;默认空用户(空密码)也可以在本地登录;
查看系统中有那些账户:无用户名、密码本地登录
[work@tri ~]$ mysql
使用有用户名的方式登录
[work@tri ~]$ mysql -u root -h localhost
mysql> select host,user,password from mysql.user;
mysql> select host,user,password from mysql.user;
+-----------+------+----------+
| host | user | password |
+-----------+------+----------+
| localhost | root | |
| tri | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
| tri | | |
+-----------+------+----------+
6 rows in set (0.00 sec)
显示结果,表示有多个 root 用户;有两个 空用户。没有一个有密码。
这就需要为每一个用户设定密码;同样需要为空用户设定密码,或者删除。
mysql.db 中的某些行,允许所有用户(包括没有密码的空账户;anonymous)访问测试数据库或者其
他以 “test_” 开头的数据库。(这个默认设置是为了测试的)
-------
修改 root 密码shell> mysql -u root
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;
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
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
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)
-----------------------------
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, CentOSroot-shell> yum install mysql mysql-server mysql-libs
root-shell> service mysqld start
root-shell> chkconfig --levels 235 mysqld on
-------
Debian,Ubuntu,Kubunturoot-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.
这段保留一点原汁原味
