1.1二進(jìn)制包安裝MySQL數(shù)據(jù)庫

1.1.1 安裝前準(zhǔn)備(規(guī)范)

1 [root@Mysql_server ~]# mkdir -p /home/zhurui/tools ##創(chuàng)建指定工具包存放路徑2 [root@Mysql_server ~]# wget http://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.5/mysql-5.5.32-linux2.6-x86_64.tar.gz ##下載二進(jìn)制包3 [root@Mysql_server tools]# tar xf mysql-5.5.32-linux2.6-x86_64.tar.gz ##解壓Mysql包4 [root@Mysql_server tools]# useradd -s /sbin/nologin -M mysql ##創(chuàng)建mysql用戶5 [root@Mysql_server tools]# id mysql6 uid=501(mysql) gid=501(mysql) groups=501(mysql)7 [root@Mysql_server ~]# mkdir /application/8 [root@Mysql_server home]# mv /home/zhurui/tools/mysql-5.5.32-linux2.6-x86_64 /application/mysql-5.5.32 9 [root@Mysql_server tools]# ll /application/ 10 total 4 11 drwxr-xr-x. 13 root root 4096 Dec 13 14:31 mysql-5.5.32 12 [root@Mysql_server tools]# ln -s /application/mysql-5.5.32/ /application/mysql ##設(shè)置軟鏈接 13 [root@Mysql_server tools]# ll /application/ 14 total 4 15 lrwxrwxrwx. 1 root root 26 Dec 13 14:39 mysql -> /application/mysql-5.5.32/ 16 drwxr-xr-x. 13 root root 4096 Dec 13 14:31 mysql-5.5.32 17 [root@Mysql_server tools]# ll /application/mysql/ 18 total 76 19 drwxr-xr-x. 2 root root 4096 Dec 13 14:31 bin 20 -rw-r--r--. 1 7161 wheel 17987 Jun 19 2013 COPYING 21 drwxr-xr-x. 3 root root 4096 Dec 13 14:31 data 22 drwxr-xr-x. 2 root root 4096 Dec 13 14:30 docs 23 drwxr-xr-x. 3 root root 4096 Dec 13 14:31 include 24 -rw-r--r--. 1 7161 wheel 7470 Jun 19 2013 INSTALL-BINARY 25 drwxr-xr-x. 3 root root 4096 Dec 13 14:31 lib 26 drwxr-xr-x. 4 root root 4096 Dec 13 14:31 man 27 drwxr-xr-x. 10 root root 4096 Dec 13 14:31 mysql-test 28 -rw-r--r--. 1 7161 wheel 2496 Jun 19 2013 README 29 drwxr-xr-x. 2 root root 4096 Dec 13 14:31 scripts 30 drwxr-xr-x. 27 root root 4096 Dec 13 14:31 share 31 drwxr-xr-x. 4 root root 4096 Dec 13 14:31 sql-bench 32 drwxr-xr-x. 3 root root 4096 Dec 13 14:31 support-files

1.1.2 初始化數(shù)據(jù)庫

-------------------------------------------------------------------- 注：如果你對python感興趣，我這有個學(xué)習(xí)Python基地，里面有很多學(xué)習(xí)資料，感興趣的+Q群：895817687 -------------------------------------------------------------------- 1 [root@Mysql_server tools]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql ##初始化數(shù)據(jù)庫2 Installing MySQL system tables...3 OK4 Filling help tables...5 OK6 [root@Mysql_server tools]# ll /application/mysql/data/ ##查看初始化結(jié)果7 total 128 drwx------. 2 mysql root 4096 Dec 13 14:45 mysql9 drwx------. 2 mysql mysql 4096 Dec 13 14:45 performance_schema 10 drwxr-xr-x. 2 mysql root 4096 Dec 13 14:31 test

1.1.3 授權(quán)Mysql管理數(shù)據(jù)庫文件

1 [root@Mysql_server ~]# chown -R mysql.mysql /application/mysql/ 2 [root@Mysql_server ~]# ll /application/mysql 3 lrwxrwxrwx. 1 mysql mysql 26 Dec 13 14:39 /application/mysql -> /application/mysql-5.5.32/

1.1.4 生成Mysql配置文件

1 [root@Mysql_server tools]# \cp /application/mysql/support-files/my-small.cnf /etc/my.cnf

1.1.5 配置啟動Mysql

1 [root@Mysql_server tools]# sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe /application/mysql/support-files/mysql.server 2 [root@Mysql_server tools]# cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld ##將生成的啟動腳本拷貝到init.d目錄下 3 [root@Mysql_server tools]# chmod +x /etc/init.d/mysqld

1.1.6 啟動Mysql

1 [root@Mysql_server tools]# lsof -i :3306 ##查詢Mysql服務(wù)是否開啟 2 [root@Mysql_server tools]# 3 [root@Mysql_server tools]# /etc/init.d/mysqld start ##啟動Mysql服務(wù) 4 Starting MySQL.... SUCCESS! 5 [root@Mysql_server tools]# lsof -i :3306 6 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME 7 mysqld 2235 mysql 10u IPv4 22761 0t0 TCP *:mysql (LISTEN) 8 [root@Mysql_server tools]#

1.1.7 配置環(huán)境變量

方法1：

1 [root@Mysql_server tools]# cp /application/mysql/bin/* /usr/local/sbin/ ##方法1

方法2：

1 [root@Mysql_server tools]# tail -1 /etc/profile 2 PATH="/application/mysql/bin:$PATH" ##尾部添加如下行 3 [root@Mysql_server tools]# source /etc/profile ##使得配置生效

1.1.8 設(shè)置及更改密碼

1 [root@Mysql_server tools]# mysqladmin -uroot password 123456 2 [root@Mysql_server tools]# mysqladmin -uroot -p123456 password zhurui
