To do so, start the server, then issue the following commands: /usr/mysql-5.6.43//bin/mysqladmin -u root password 'new-password' /usr/mysql-5.6.43//bin/mysqladmin -u root -h localhost.localdomain password 'new-password' Alternatively you can run: /usr/mysql-5.6.43//bin/mysql_secure_installation which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with: cd . ; /usr/mysql-5.6.43//bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl cd mysql-test ; perl mysql-test-run.pl Please report any problems at http://bugs.mysql.com/ The latest information about MySQL is available on the web at http://www.mysql.com Support MySQL by buying support/licenses at http://shop.mysql.com New default config file was created as /usr/mysql-5.6.43//my.cnf and will be used by default by the server when you start it. You may edit this file to change server settings WARNING: Default config file /etc/my.cnf exists on the system This file will be read by default by the MySQL server If you do not want to use this, either remove it, or use the --defaults-file argument to mysqld_safe when starting the server
拷貝 my-default.cnf到/etc/my.cnf
# cd ../support-files/
# cp my-default.cnf /etc/my.cnf
[root@localhost scripts]# cd ../support-files/ [root@localhost support-files]# [root@localhost support-files]# ls binary-configure magic my-default.cnf mysqld_multi.server mysql-log-rotate mysql.server [root@localhost support-files]# [root@localhost support-files]# cp my-default.cnf /etc/my.cnf cp: overwrite ‘/etc/my.cnf’? yes [root@localhost support-files]#
向/etc/init.d中添加mysql的啓動服務
init.d目錄包含許多系統各類服務的啓動和中止腳本。
[root@localhost support-files]# pwd /usr/mysql-5.6.43/support-files [root@localhost support-files]# ls binary-configure magic my-default.cnf mysqld_multi.server mysql-log-rotate mysql.server [root@localhost support-files]# cp mysql.server /etc/init.d/mysqld [root@localhost support-files]#
修改/etc/init.d/mysqld權限
# cd /etc/init.d/
# chmod 755 mysqld
[root@localhost support-files]# cd /etc/init.d/ [root@localhost init.d]# [root@localhost init.d]# ls functions mysqld netconsole network README [root@localhost init.d]# [root@localhost init.d]# chmod -R 755 mysqld [root@localhost init.d]# [root@localhost init.d]# ll total 44 -rw-r--r--. 1 root root 13948 Sep 16 2015 functions -rwxr-xr-x. 1 root root 10565 May 24 20:14 mysqld -rwxr-xr-x. 1 root root 2989 Sep 16 2015 netconsole -rwxr-xr-x. 1 root root 6630 Sep 16 2015 network -rw-r--r--. 1 root root 1160 Nov 20 2015 README
修改/etc/init.d/mysqld
# vi /etc/init.d/mysqld
配置環境變量
將MySQL配置到環境變量中，這樣就能夠在任何地方用mysql命令了
# vi /etc/profile
在最後添加
#mysql export MYSQL_HOME=/usr/mysql-5.6.43 #PATH export PATH=$MYSQL_HOME/bin:$PATH
執行以下指令，使上述配置當即生效
# source /etc/profile
啓動MySQL
# /etc/init.d/mysqld start
