$ /mysql/scripts/mysql_install_db --datadir=/mysql/data --basedir=/mysql

support-files/mysql.server脚本启动mysql不推荐，推荐使用mysqld_safe启动：

$ mysqld_safe --defaults-file=/mysql/conf/my.cnf &

netstat -lnt |grep 3306

ps -ef |grep mysql 查看mysql端口和进程

配置mysql

mysql5.6默认root用户不设密码的直接敲入mysql登录。

增强安全性：

select user,host from mysql.user;

+------+-----------+

| user | host |

+------+-----------+

| root | 127.0.0.1 |

| root | ::1 |

| | linux01 |

| root | linux01 |

| | localhost |

| root | localhost |

+------+-----------+

6 rows in set (0.01 sec)

6个用户，两个用户没有用户名。所以直接可通过mysql登录。

下面保留一条root用户其他用户全部删除。

修改root用户名

update mysql.user set user=‘system‘,password=password(‘oralinux‘);

(root@localhost) [(none)]>select * from mysql.db \G

truncate table mysql.db;

root@localhost) [(none)]>exit

Bye

[mysql@linux01 mysql]$ mysql

创建管理脚本，创建中间定义文件，目的是提高脚本的复用性：

vi /mysql/scripts/mysql_env.ini

#set env

MYSQL_USER=system

MYSQL_PASS=‘oralinux‘

#check parameter

if [ $# -ne 1 ]

then

HOST_PORT=3306

else

HOST_PORT=$1

fi

$ chmod 600 /mysql/scripts/mysql_env.ini

创建mysql_db_startup.sh脚本，用于启动mysql服务：

#!/bin/sh

# Created by jason

source /mysql/scripts/mysql_env.ini

echo "Startup MySQL Service:localhost_"${HOST_PORT}

/mysql/bin/mysqld_safe --defaults-file=/mysql/conf/my.cnf &

$ vi /mysql/scripts/mysql_db_shutdown.sh

#!/bin/sh

#Created by jason

source /mysql/scripts/mysql_env.ini

echo "Shutdown MySQL Service:localhost_"${HOST_PORT}

/mysql/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PASS} -S /mysql/conf/mysql.sock shutdown

创建sqlplus.sh脚本用于快速登录：

$vi /mysql/scripts/sqlplus.sh

#!/bin/sh

#Created by jason

source /mysql/scripts/mysql_env.ini

echo "Login MySQL Service:localhost_"${HOST_PORT}

/mysql/bin/mysql -u${MYSQL_USER} -p${MYSQL_PASS} -S /mysql/conf/mysql.sock $2

chmod +x /mysql/scripts/sqlplus.sh

编辑mysql用户变量，将上述路径加入到PATH中

echo "export PATH=/mysql/scripts:\$PATH" >> ~/.bash_profile

source ~/.bash_profile

设置开机启动：root下

# vi /etc/rc.localhost

# autostart mysql ,added by jason at 2017-03-31

sudo -i -u mysql /mysql/scripts/mysql_db_startup.sh 3306 > /mysql/logs/mysql_db_startup.log 2>&1

执行sudo命令遇到下列错误：

sudo:sorry,you must have a tty to run sudo

vi /etc/sudoers 注释掉56行

#Defaultsrequiretty
