学习linux有段时间了,一直没有写技术博客的习惯,但还是尽量让自己多写写自己学到的一些关于linux方面的东西吧,最近在双星葛老师的指导下开始学习mysql数据库,自己整理笔记,并用shell脚本实现mysql源码包(mysql-5.6.11.tar.gz)的 全自动安装,代码写的一般,但是能满足需求,如安装有什么问题可以互相交流一些,下面进入正题:
首先整理一下自己手动安装时的一些步骤:
安装和配置mysql的源码包
软件包版本:mysql-5.6.11.tar.gz
1.安装源码包所需要的前提软件包
需要的软件包:cmake make gcc gcc-c++ ncurses-devel mysql
yum install cmake make gcc gcc-c++ ncurses-devel mysql -y
2.解压源码包并进行编译安装
[root@localhost ~]# tar xf mysql-5.6.11.tar.gz [root@localhost ~]# cd mysql-5.6.11 [root@localhost mysql-5.6.11]# cmake \ -DCMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql12 \ -DMYSQL_DATADIR:PATH=/database \ -DWITH_DEBUG:BOOL=on \ -DWITH_EXTRA_CHARSETS:STRING=all \ -DWITH_INNOBASE_STORAGE_ENGINE:BOOL=on \ -DWITH_PARTITION_STORAGE_ENGINE:BOOL=on [root@localhost mysql-5.6.11]# make ; make install
cmake make就会调用gcc、gcc-c++编译器来编译源代码文件
make install 安装到/usr/local/mysql12
3.创建并修改配置文件
进入到安装目录,创建配置文件my.cnf
[root@localhost mysql-5.6.11]# cd /usr/local/mysql12 [root@localhost mysql12]# mkdir etc [root@localhost mysql12]# vim etc/my.cnf [mysqld] basedir=/usr/local/mysql12 datadir=/database socket=/var/run/mysqld/mysql12.sock pid-file=/var/run/mysqld/mysql12.pid port=3308 user=mysql [mysqld_safe] log-error=/var/log/mysqld/mysql12-error.log
4.创建mysql组和用户,并保证用户uid27 gid27
查看本机是否有mysql用户
[root@localhost mysql12]#cat /etc/passwd |grep mysql mysql:x:27:27:MySQL Server:/var/lib/mysql:/bin/bash
没有的话则进行创建,命令如下
[root@localhost mysql12]# groupadd mysql -g 27 [root@localhost mysql12]# useradd mysql -u 27 -c "Mysql Server" -d /var/lib/mysql -s /sbin/nologin -g mysql
5.创建所需文件夹并修改所有者为mysql
[root@localhost mysql12]# mkdir /database [root@localhost mysql12]# mkdir /var/run/mysqld/ [root@localhost mysql12]# mkdir /var/log/mysqld/ [root@localhost mysql12]# chown mysql:mysql /database /var/run/mysqld/ /var/log/mysqld/ /usr/local/mysql12 -R
6.初始化数据
进入源码包解压後的文件夹下的script目录执行mysql_install_db脚本进行初始化
[root@localhost mysql12]# cd ~/mysql-5.6.11/scripts/ [root@localhost scripts]# chmod +x mysql_install_db [root@localhost scripts]# ./mysql_install_db --datadir=/database/ --basedir=/usr/local/mysql12/ --user=mysql
7.定义启动脚本的位置并修改脚本
复制解压目录下的support-files目录中的mysql.server到/etc/rc.d/init.d/目录下并将其重命名为mysql56,并进行如下修改作为启动脚本。
[root@localhost scripts]# cd ~/mysql-5.6.11/support-files/ [root@localhost support-files]# chmod +x mysql.server [root@localhost support-files]# cp mysql.server /etc/rc.d/init.d/mysql12 [root@localhost support-files]# vim /etc/rc.d/init.d/mysql12 修改 conf=/etc/my.cnf 为conf=/usr/local/mysql12/etc/my.cnf
8.启动mysql
查看系统中是否有mysql的进程
[root@localhost support-files]# netstat -ntaup | grep "mysql" [root@localhost support-files]# ps aux | grep "mysql"
如果有则将其进程结束,命令如下
[root@localhost support-files]# pkill -9 mysql
启动刚安装好的mysql
[root@localhost support-files]# service mysql12 start [root@localhost support-files]# mysql -S/var/run/mysqld/mysql12.sock
出现如下提示则说明mysql源码包安装成功并可以使用

如需要在一台主机重复安装,只需要将脚本中的mysql变量进行修改即可。
