配置YUM (本地)
[[email protected] yum.repos.d]# cat CentOS-Base.repo
[base]
baseurl=file:///mnt
enabled=1
gpgcheck=0
实验环境:
[[email protected] yum.repos.d]# cat /etc/centos-release
CentOS release 6.6 (Final)
建mysql用户:
[[email protected] mysql-5.6.36]# useradd -s /sbin/nologin -M mysql
[[email protected] mysql-5.6.36]# mkdir -p /home/oldboy/tools
[[email protected] mysql-5.6.36]# tar zxvf mysql-5.6.36.tar.gz
[[email protected] mysql-5.6.36]# cd mysql-5.6.36
[[email protected]ysqlserver mysql-5.6.36]# mkdir -p /application/mysql-5.6.36/data

[[email protected] mysql-5.6.36]# make && make install
为MySQL安装路径设置不带版本号的软链接/application/mysql,操作命令如下:
[[email protected] ~]# ln -s /application/mysql-5.6.36/ /application/mysql
[[email protected] ~]# mv /etc/my.cnf /etc/my.cnf.bak
#提示:在CentOS6.8版操作系统最小化安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字,如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。
#在启动MySQL服务时,会按照一定的顺序搜索my.cnf,先在/etc目录下找,找不到则会搜索"$basedir/my.cnf",在本例中就是/application/mysql-5.6.36/my.cnf,这是新版MySQL的配置文件的默认位置!
授权:
[[email protected] application]# chown -R mysql.mysql /application/mysql/
[[email protected] application]# chmod -R 1777 /tmp
配置环境变量:
[[email protected] application]# echo ‘export PATH=/application/mysql/bin:$PATH‘>>/etc/profile
[[email protected] application]# source /etc/profile
[[email protected] application]# echo $PATH
[[email protected] application]# cd /application/mysql/scripts/
[[email protected]]#./mysql_install_db --basedir=/application/mysql/--datadir=/application/mysql/data --user=mysql
报错:

是字符集和字符冲突了,所以编译的时候要把字符和字符集选项都加上,并且要兼容!修改编译参数:
注意事项:
重新编译时,需要清除旧的对象文件和缓存信息。

#从上文说明中可以看到数据库启动时会读取/etc/my.cnf,因此有可能会导致无法启动,避免的方法就是使用mysqld_safe启动服务时采用--defaults-file参数指定配置文件,前文已将/etc/my.cnf改名了,所以,就不需要指定参数了,这里是一个坑,读者要注意。
此步骤必须要初始化成功,否则,后面会出现登录不了数据库等各种问题。
设置MySQL启动脚本

[[email protected] mysql-5.6.36]# pwd
/home/oldboy/tools/mysql-5.6.36
[[email protected] mysql-5.6.36]# cp support-files/mysql.server /etc/init.d/mysqld #<==拷贝mysql启动脚本到mysql的命令路径
[[email protected] mysql-5.6.36]# chmod 700 /etc/init.d/mysqld
[[email protected] mysql-5.6.36]# ls -l /etc/init.d/mysqld
