注:以下所有操作都在CentOS 6.5 x86_64位系統(tǒng)下完成。

#準(zhǔn)備工作#

在安裝MySQL之前,請確保已經(jīng)使用yum安裝了以下各類基礎(chǔ)組件(如果系統(tǒng)已自帶,還可以考慮yum update下基礎(chǔ)組件):

gcccmakeopenssl+openssl-develpcre+pcre-develbzip2+bzip2-devellibcurl+curl+curl-devellibjpeg+libjpeg-devellibpng+libpng-develfreetype+freetype-develphp-mcrypt+libmcrypt+libmcrypt-devellibxslt+libxslt-develgmp+gmp-devellibxml2+libxml2-develmhashncurses+ncurses-develxml2

然后創(chuàng)建mysql的用戶組和用戶,并且不允許登錄權(quán)限:

# id mysqlid: mysql:無此用戶# groupadd mysql# useradd -g mysql -s /sbin/nologin mysql# id mysqluid=500(mysql) gid=500(mysql) 組=500(mysql)

#MySQL的安裝#

給MySQL的安裝準(zhǔn)備目錄:

# mkdir -p /data/mysql/data# chown -R mysql:mysql /data/mysql

開始源碼安裝MySQL:

# cd /usr/local/src# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.10.tar.gz# tar zxf mysql-5.6.10.tar.gz# cd mysql-5.6.10# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.6.10 -DSYSCONFDIR=/usr/local/mysql-5.6.10/etc -DMYSQL_UNIX_ADDR=/usr/local/mysql-5.6.10/tmp/mysql.sock -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DMYSQL_DATADIR=/data/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1...CMake Warning:Manually-specified variables were not used by the project:MYSQL_USER-- Build files have been written to: /usr/local/src/mysql-5.6.10# make && make install# mkdir -p /usr/local/mysql-5.6.10/etc# mkdir -p /usr/local/mysql-5.6.10/tmp# ln -s /usr/local/mysql-5.6.10/ /usr/local/mysql# chown -R mysql:mysql /usr/local/mysql-5.6.10# chown -R mysql:mysql /usr/local/mysql

給當(dāng)前環(huán)境添加MySQL的bin目錄:

# vim /etc/profileexport MYSQL_HOME=/usr/local/mysqlexport PATH=$PATH:$MYSQL_HOME/bin$ source /etc/profile

執(zhí)行初初始化配置腳本并創(chuàng)建系統(tǒng)自帶的數(shù)據(jù)庫和表:

# cd /usr/local/mysql# scripts/mysql_install_db --user=mysql --datadir=/data/mysql/data...OKTo start mysqld at boot time you have to copysupport-files/mysql.server to the right place for your systemPLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !To do so, start the server, then issue the following commands:./bin/mysqladmin -u root password 'new-password'./bin/mysqladmin -u root -h iZ94mobdenkZ password 'new-password'Alternatively you can run:./bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default. This isstrongly recommended for production servers.See the manual for more instructions.You can start the MySQL daemon with:cd . ; ./bin/mysqld_safe &You can test the MySQL daemon with mysql-test-run.plcd mysql-test ; perl mysql-test-run.plPlease report any problems with the ./bin/mysqlbug script!The latest information about MySQL is available on the web athttp://www.mysql.comSupport MySQL by buying support/licenses at http://shop.mysql.comWARNING: Found existing config file ./my.cnf on the system.Because this file might be in use, it was not replaced,but was used in bootstrap (unless you used --defaults-file)and when you later start the server.The new default config file was created as ./my-new.cnf,please compare it with your file and take the changes you need.WARNING: Default config file /etc/my.cnf exists on the systemThis file will be read by default by the MySQL serverIf you do not want to use this, either remove it, or use the--defaults-file argument to mysqld_safe when starting the server

注:由于MySQL在啟動的時候,會先去/etc/my.cnf找配置文件,如果沒有找到則搜索$basedir/my.cnf,也即/usr/local/mysql-5.6.10/my.cnf,所以必須確保/etc/my.cnf沒有存在,否則可能導(dǎo)致無法啟動。

實(shí)際操作上發(fā)現(xiàn)系統(tǒng)上存在該文件,所以這里可能需要將該文件先備份改名,然后再根據(jù)上面的配置寫配置文件:

# mv /etc/my.cnf /etc/my.cnf.bak# vim /usr/local/mysql-5.6.10/my.cnf[mysqld]basedir=/usr/local/mysql-5.6.10datadir=/data/mysql/datasocket=/usr/local/mysql-5.6.10/tmp/mysql.sockuser=mysqlsql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

修改MySQL用戶root的密碼,這里使用mysqld_safe安全模式啟動:

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &[1] 3970[root@iZ94mobdenkZ ~]# 141230 19:02:31 mysqld_safe Logging to '/data/mysql/data/centos.err'.141230 19:02:32 mysqld_safe Starting mysqld daemon with databases from /data/mysql/data

這個時候已經(jīng)啟動了mysqd_safe安全模式,另開一個窗口作為客戶端連入MySQL服務(wù)器:

# mysqlWelcome to the MySQL monitor. Commands end with ; or /g.Your MySQL connection id is 1Server version: 5.6.10 Source distributionCopyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.Oracle is a registered trademark of Oracle Corporation and/or itsaffiliates. Other names may be trademarks of their respectiveowners.Type 'help;' or '/h' for help. Type '/c' to clear the current input statement.mysql> use mysql;mysql> update user set password=password('yourpassword') where user='root';mysql> flush privileges;mysql> exit;

修改完畢之后使用kill把mysqld_safe進(jìn)程殺死:

# ps aux | grep mysqlroot 3970 0.0 0.2 106308 1492 pts/1 S 19:02 0:00 /bin/sh /usr/local/mysql/bin/mysqld_safe --user=mysql --skip-grant-tables --skip-networkingmysql 4143 0.1 18.0 558280 90316 pts/1 Sl 19:02 0:00 /usr/local/mysql-5.6.10/bin/mysqld --basedir=/usr/local/mysql-5.6.10 --datadir=/data/mysql/data --plugin-dir=/usr/local/mysql-5.6.10/lib/plugin --user=mysql --skip-grant-tables --skip-networking --log-error=/data/mysql/data/centos.err --pid-file=/data/mysql/data/centos.pid --socket=/usr/local/mysql-5.6.10/tmp/mysql.sockroot 4313 0.0 0.1 103252 836 pts/0 S+ 19:05 0:00 grep mysql# kill -9 3970# kill -9 4143

或者回到剛才啟動mysqld_safe的窗口ctrl+c將進(jìn)程殺死也行。

復(fù)制服務(wù)啟動腳本:

# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld# chmod +x /etc/init.d/mysqld

設(shè)置開機(jī)啟動MySQL服務(wù)并正常開啟MySQL服務(wù)(非必要項):

# chkconfig mysqld on# service mysqldUsage: mysqld {start|stop|restart|reload|force-reload|status} [ MySQL server options ]# service mysqld startStarting MySQL.

以后就可以直接通過service mysqld命令來開啟/關(guān)閉MySQL數(shù)據(jù)庫了。

最后,建議生產(chǎn)環(huán)境下運(yùn)行安全設(shè)置腳本,禁止root用戶遠(yuǎn)程連接,移除test數(shù)據(jù)庫和匿名用戶等:

# /usr/local/mysql-5.6.10/bin/mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQLSERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!In order to log into MySQL to secure it, we'll need the currentpassword for the root user. If you've just installed MySQL, andyou haven't set the root password yet, the password will be blank,so you should just press enter here.Enter current password for root (enter for none):

注:上面輸入的root密碼指的是前面設(shè)置的MySQL的root賬戶的密碼。

至此,MySQL數(shù)據(jù)庫已經(jīng)安裝完畢。

#MySQL的安全配置#

1、確保啟動MySQL不能使用系統(tǒng)的root賬號,必須是新建的mysql賬號,比如:

# mysqld_safe --user=mysql

2、MySQL安裝好運(yùn)行初始化數(shù)據(jù)庫后,默認(rèn)的root賬戶密碼為空,必須給其設(shè)置一個密碼,同時保證該密碼具有較高的安全性。比如:

mysql> user mysql;mysql> update user set password=password('yourpassword') where user='root';mysql> flush privileges;

3、刪除默認(rèn)數(shù)據(jù)庫及用戶:

mysql> show databases;+--------------------+| Database |+--------------------+| information_schema || mysql || performance_schema || test |+--------------------+mysql> drop daabase test;mysql> use mysql;mysql> select host,user from user;+--------------+------+| host | user |+--------------+------+| 127.0.0.1 | root || ::1 | root || centos | || centos | root || localhost | || localhost | root |+--------------+------+mysql> delete from user where not(host='localhost' and user='root');mysql> flush privileges;

注:上面的user表中的數(shù)據(jù)可能會有所不同。

4、當(dāng)開發(fā)網(wǎng)站連接數(shù)據(jù)庫的時候,建議建立一個用戶只針對某個庫有update/select/delete/insert/drop table/create table等權(quán)限,減小某個項目的數(shù)據(jù)庫的用戶名和密碼被竊取后造成其他項目受影響,比如:

mysql>create database yourdbname default charset utf8 collate utf8_general_ci;mysql>create user 'yourusername'@'localhost' identified by 'yourpassword';mysql> grant select,insert,update,delete,create,drop privileges on yourdbname.* To 'yourusername'@localhost identified by 'yourpassword';

5、數(shù)據(jù)庫文件所在的目錄不允許未經(jīng)授權(quán)的用戶訪問,需要控制對該目錄的訪問,比如:

# chown -R mysql:mysql /data/mysql/data# chmod -R go-rwx /data/mysql/data
