CentOS系統安裝mysql5資料庫兩種方法

簡單點說，就是yum安裝軟體容易點，會自動解決各個包的依賴關係。rpm就一個軟體包。

CentOS下以RPM方式安裝MySQL5.5

首先去http://dev.mysql.com/downloads/mysql/5.5.html#downloads網站下載：

分別下載以下三個檔案（由於我的機器是32位，下面是32位版本的包，如果你的機器是64位的請下載64位版本）：

MySQL-server-5.5.16-1.rhel5.i386.rpm

MySQL-client-5.5.16-1.rhel4.i386.rpm

MySQL-devel-5.5.16-1.rhel4.i386.rpm

使用wget命令使用斷點傳輸的方式將這三個檔案下載

 

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-server-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-client-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

wget -c http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-devel-5.5.16-1.rhel4.i386.rpm/from/http://mysql.spd.co.il/

 

下載完成後開始安裝：

rpm -ivh MySQL-server-5.5.16-1.rhel4.i386.rpm MySQL-client-5.5.16-1.rhel4.i386.rpm MySQL-devel-5.5.16-1.rhel4.i386.rpm

 

提示安裝完成後，輸入mysql 看是否安裝成功

mysql

 

如果出現如下錯誤資訊：(www.111cn.net)

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

說明mysql服務還沒有啟動，輸入service mysql start啟動mysql服務

service mysql start

 

然後再輸入mysql，若出現以下提示資訊，說明成功。

首次安裝時，預設密碼為空白，可以使用如下命令修改root密碼，

mysqladmin -u root  password mypassword

mypassword 為你設定的新密碼

然後再次登入

mysql -u root –p

 

rpm包安裝的MySQL是不會安裝/etc/my.cnf檔案的，解決方案，只需要複製/usr/share/mysql目錄下的my-huge.cnf 檔案到/etc目錄，並改名為my.cnf即可

cp /usr/share/mysql/my-huge.cnf /etc/my.cnf

 

配置遠端存取

處於安全考慮，Mysql預設是不允許遠端存取的，可以使用下面開啟遠端存取

//賦予任何主機訪問資料的許可權：(www.111cn.net)
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION

//使修改生效
mysql>FLUSH PRIVILEGES

如果依然不能遠端存取的話，那就很可能防火牆的原因了，可以在防火牆中開啟3306連接埠或者乾脆關掉防火牆。

 CentOS 6.3源碼安裝mysql 5.6方法

1：下載mysql

下載地址為：http://www.mysql.com/downloads/mysql/5.6.html#downloads

選擇"Source Code"->"
Generic Linux (Architecture Independent), Compressed TAR Archive"

 

 

2：安裝必要的軟體包

yum -y install gcc gcc-c++ gcc-g77 autoconf automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* make cmake

3:編譯安裝

[root@server100 ~]# groupadd mysql

[root@server100 ~]# useradd -r -g mysql mysql

[root@server100 ~]# tar -zxvf mysql-5.6.10.tar.gz

[root@server100 ~]# cd mysql-5.6.10

[root@server100 mysql-5.6.10]# cmake .

[root@server100 mysql-5.6.10]# make && make install

-------------預設安裝目錄為/usr/local/mysql

[root@server100 ~]# chown -R mysql.mysql /usr/local/mysql

[root@server100 ~]# cd /usr/local/mysql/scripts

[root@server100 ~]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

[root@server100 ~]# cd /usr/local/mysql/support-files

[root@server100 support-files]# cp mysql.server /etc/rc.d/init.d/mysql

[root@server100 support-files]# cp my-default.cnf /etc/my.cnf

[root@server100 ~]# chkconfig --add mysql

[root@server100 ~]# chkconfig mysql on

[root@server100 ~]# service mysql start

Starting MySQL SUCCESS!

[root@server100 support-files]# mysql
