RHEL下安装mysql
1.到mysql的网站(必须到官方网站下载,防止数据被修改,纂改过)下载四个必须rpm 安装包:
http://dev.mysql.com/downloads/m ... nux-rhel5-ia64-rpms MySQL-client-5.1.16-0.glibc23.i386.rpm MySQL-devel-5.1.16-0.glibc23.i386.rpm MySQL-server-5.1.16-0.glibc23.i386.rpm MySQL-shared-5.1.16-0.glibc23.i386.rpm 2. 通过ssh远程控制工具传到服务器上,放在适当的目录下(如:/opt/mysql/mysql5.1.16) 3.进入目录(/opt/mysql/mysql5.1.16)下安装msyql: rpm 文件是Red Hat公司开发的软件安装包,rpm可让Linux在安装软件包时免除许多复杂的手续。该命令在安装时常用的参数是 –ivh ,其中i表示将安装指定的rmp软件包,V表示安装时的详细信息,h表示在安装期间出现"#"符号来显示目前的安装过程。这个符号将持续到安装完成后才停止。 [root@qudee mysql5.1.16]# rpm –ivh MySQL-client-5.1.16-0.glibc23.i386.rpm [root@qudee mysql5.1.16]# rpm –ivh MySQL-devel-5.1.16-0.glibc23.i386.rpm [root@qudee mysql5.1.16]# rpm –ivh MySQL-shared-5.1.16-0.glibc23.i386.rpm [root@qudee mysql5.1.16]# rpm –ivh MySQL-server-5.1.16-0.glibc23.i386.rpm 显示如下信息 warning: MySQL-server-5.1.16-0.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%] 1:MySQL-server ########################################### [100%] PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER ! To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h localhost password 'new-password' See the manual for more instructions. NOTE: If you are upgrading from a MySQL <= 3.22.10 you should run the /usr/bin/mysql_fix_privilege_tables. Otherwise you will not be able to use the new GRANT command! Please report any problems with the /usr/bin/mysqlbug script! The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses athttps://order.mysql.com Starting MySQL...................................[失败] 4.查看已安装的包 [root@qudee mysql5.1.20]# rpm -qa | grep -i mysql 或者 [root@qudee mysql5.1.20]# rpm -qa | grep mysql MySQL-devel-5.1.20-0.glibc23 MySQL-shared-5.1.20-0.glibc23 MySQL-client-5.1.20-0.glibc23 MySQL-server-5.1.20-0.glibc23 5.查看[root@qudee /]# locate mysql.server 的路径 /usr/share/man/man1/mysql.server.1.gz /usr/share/mysql/mysql.server 复制并更名 [root@qudee /]#cp /usr/share/mysql/mysql.server /etc/init.d/mysqld 6.查看[root@qudee /]# locate my-huge.cnf 的路径 /usr/share/doc/MySQL-server-5.1.16/my-huge.cnf /usr/share/mysql/my-huge.cnf 复制并更名[root@qudee /]#cp /usr/share/mysql/my-huge.cnf /etc/my.cnf 7.启动服务: service mysqld start Starting MySQL [ OK ] 启动成功!恭喜~~~ 8.编辑vi /etc/my.cnf 这个文件,设置字符集,支持国际化. default-character-set=utf8 //在此添加字符集 # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3306 #socket = /var/lib/mysql/mysql.sock skip-locking key_buffer = 384M max_allowed_packet = 1M table_cache = 512 sort_buffer_size = 2M read_buffer_size = 2M read_rnd_buffer_size = 8M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size = 32M default-character-set=utf8 //在此添加字符集 # Try number of CPU's*2 for thread_concurrency thread_concurrency = 16 先按Esc, 再同时按Shift + ; 再输入wq! (推出并保存) 呵呵! 字符集就配置好了~~~ 9.MySQL默认的数据文件存储目录为/var/lib/mysql。假如要把目录移到/qudeedata/dbdata/mysql5.1.16下需要进行下面几步: (1)、/qudeedata/dbdata目录下建立mysql5.1.16目录 cd /qudeedata/dbdata mkdir mysql5.1.16 (2)、把MySQL服务进程停掉: service mysqld stop (3)、把/var/lib/mysql整个目录移到/qudeedata/dbdata/mysql5.1.16 mv /var/lib/mysql /qudeedata/dbdata/mysql5.1.16 这样就把MySQL的数据文件移动到了/qudeedata/dbdata/mysql5.1.16 下 (4)、编辑MySQL的配置文件/etc/my.cnf 为保证MySQL能够正常工作,需要指明mysql.sock文件的产生位置。修改socket=/var/lib/mysql/mysql.sock一行中等号右边的值为: /qudeedata/dbdata/mysql5.1.16/mysql/mysql.sock 。操作如下: 命令: vi my.cnf (用vi工具编辑my.cnf文件,找到下列数据修改之) # The MySQL server [mysqld] port = 3306 #socket = /var/lib/mysql/mysql.sock(原内容,为了更稳妥用"#"注释此行) socket = /qudeedata/dbdata/mysql5.1.16/mysql/mysql.sock (加上此行) (5)、修改MySQL启动脚本/etc/rc.d/init.d/mysqld 最后,需要修改MySQL启动脚本/etc/rc.d/init.d/mysqld,把其中datadir=/var/lib/mysql一行中,等号右边的路径改成你现在的实际存放路径: /qudeedata/dbdata/mysql5.1.16。 [root@test1 etc]# vi /etc/rc.d/init.d/mysqld #datadir=/var/lib/mysql (注释此行) datadir=/qudeedata/dbdata/mysql5.1.16 (加上此行) 10、自动启动 1)察看mysql是否在自动启动列表中 [root@qudee /]# chkconfig –list 2)把MySQL添加到你系统的启动服务组里面去 [root@qudee /]# chkconfig – add mysql 11.测试通过命令是否能够启动,停止,重启 结果: [root@qudee /]# service mysqld start Starting MySQL [ OK ] [root@qudee /]# service mysqld restart Shutting down MySQL.. [ OK ] Starting MySQL [ OK ] [root@qudee /]# service mysqld stop Shutting down MySQL... [ OK ] [root@qudee /]# /etc/init.d/mysqld start Starting MySQL [ OK ] [root@qudee /]# /etc/init.d/mysqld restart Shutting down MySQL... [ OK ] Starting MySQL [ OK ] [root@qudee /]# /etc/init.d/mysqld stop Shutting down MySQL.. [ OK ] 证明,成功安装mysql.注:还可以通过添加,查询,删除数据库中的数据进行操作. 12.完成安装! |
