环境要求：centos：6.8
                MySQL：5.7.20
                MySQL安装文件名：mysql-5.7.20-linux-glibc2.12-x86_64.tar.gz
                MySQL源文件路径：/usr/local/src
                MYSQL脚本文件：/usr/local/src/install_mysql.sh

1、脚本如下：

1. #/bin/sh

2. #px 2017-11-29

3. #mysql install

4. #email:kitten-pan@163.com & 752684428

5. #version 2.0

6. #mysql-version mysql5.7.20

8. source_path=/usr/local/src

9. install_path=/usr/local/mysql

10. install_name=mysql-5.7.20-linux-glibc2.12-x86_64

12. ##检测本机环境

13. env_fun()

14. {

15. echo "============检测本机环境,please wait ..."

16. username=`cat /etc/passwd |grep mysql|cut -c 1-5`

17.     if [ "$username" = "mysql" ];then

18.         echo "MySQL account is exits..."

19.         return 10

20.     else

21.         echo "mysql account is not exits,ready add..."

22.         groupadd mysql

23.         useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql

24.         return 12

25.     fi

26. }

28. ##判断MySQL是否安装

29. check_fun()

30. {

31. rpm_name=`rpm -aq |grep mysql-server`

32. echo $rpm_name

33.     if [ ! $rpm_name ];then

34.         echo "begin check the source install,please wait for a moment..."

35.             if [ -d $install_path ];then

36.                 echo "source install is exist,quit..."

37.                 exit 0

38.             else

39.                 echo "本机未安装MySQL,稍后为你安装..."

40.                 install_fun

41.                 op_fun

42.                 

43.             fi

44.     else

45.         echo -n "rpm MySQL已经安装，是否删除？[yes|no]"

46.         read select

47.             if [ $select = yes ];then

48.                 rpm -e $rpm_name --nodeps

49.                 rm -rf /var/log/mysqld.log

50.                 check_fun

51.             else

52.                 exit 0

53.             fi

54.     fi

55. }

57. ###安装MySQL

58. install_fun()

59. {

60. read  -p "Input a mysql version:" -t 30  mysql_version

61. read  -p "Input a mysql port:" -t 30  mysql_port

62. read  -p "Input a mysql_server_id:" -t 30 mysql_server_id

63. cd $source_path && echo "解压中,please waiting..."

64. tar -zxvf ${install_name}.tar.gz && mv $install_name $install_path

65. ##创建数据目录

66. mkdir -pv /data/mysqldata

67. ###给MySQL目录的MySQL账号权限

68. cd /usr/local && chown mysql.mysql mysql

69. chown -R mysql.mysql /data/mysqldata

70. cd $install_path && bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysqldata

193. }

194. main

195. exit 0

2、执行自动安装脚本
    需要填写MySQL的版本信息、端口信息、serverid信息等

点击(此处)折叠或打开

1. sh install_mysql.sh

2. ###==================================================###

3. ###welcome to make install mysql with this script###

4. ###copyright 2013 by px###

5. ###==================================================###

6. ============检测本机环境,please wait ...

7. mysql account is not exits,ready add...

9. begin check the source install,please wait for a moment...

10. 本机未安装MySQL,稍后为你安装...

11. Input a mysql version:5.7.20

12. Input a mysql port:3309

13. Input a mysql_server_id:1

14. 解压中,please waiting...

3、自动安装完毕 启动

# service mysqld  restart
MySQL server PID file could not be found!                  [FAILED]
Starting MySQL.............                                          [  OK  ]

4、登入MySQL 修改密码

点击(此处)折叠或打开

1. [root@ct562 mysqldata]# mysql -uroot -p

2. Enter password:

3. Welcome to the MySQL monitor. Commands end with ; or \g.

4. Your MySQL connection id is 3
