linux二进制安装mysql,以及使用/etc/init.d/mysqld启动mysql出现的错误和解决方法

​​源码包下载​​

​​二进制​​（i686是32位操作系统   x86_64 是64位操作系统）

可以​​右击复制链接地址，在服务器上面wget ​​

​​二进制的安装步骤​​

1.​​上传压缩包并解压​​

[root@localhost ~]# tar xf mysql-5.6.10-linux-glibc2.5-x86_64.tar.gz

2.​​创建msyql安装目录 ​​

[root@localhost ~]# mkdir /lm

3.​​移动mysql程序到安装目录​​

[root@localhost ~]# mv mysql-5.6.10-linux-glibc2.5-x86_64 /lm/mysql-5.6.10

4.创建​​软连接​​

​​cd 到软连接里面 cd support-files 拷贝脚本​​

​​覆盖系统文件my.cnf​​

​​cp my-default.cnf /etc/my.cnf​​

​​覆盖启动脚本​​

​​cp mysql.server /etc/init.d/mysqld​​

[root@localhost mysql]# ln -s /lm/mysql-5.6.10 /lm/mysql
[root@localhost mysql]# cd support-files/
[root@localhost support-files]# ll

[root@localhost support-files]# cp my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
[root@localhost support-files]# cp mysql.server /etc/init.d/mysqld

初始化

​​进入初始化目录​​

cd mysql/scripts

​​创建mysql用户​​

[root@localhost scripts]# useradd mysql -s /sbin/nologin -M

​​安装初始化依赖​​

cd /lm/mysql/scripts
   yum install -y autoconf
   ./mysql_install_db --user=mysql --basedir=/lm/mysql --datadir=/lm/mysql/data/

​​启动mysqld​​

[root@localhost bin]# /etc/init.d/mysqld start
Starting MySQL. SUCCESS!

​​添加环境变量​​

[root@localhost lm]# cat /etc/profile.d/mysql.sh
export PATH="/lm/mysql/bin:$PATH"

​​进入mysql，查看mysql用户​​

[root@localhost lm]# mysql

​​启动mysql报错1：​​

[root@localhost bin]# /etc/init.d/mysqld start
/etc/init.d/mysqld: line 256: /usr/local/mysql/bin/my_print_defaults: Permission denied
Starting MySQL. ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid).

​​原因：​​

​编辑/etc/my.cnf 文件，因为缺少basedir 和 datadir 两个路径，在 [mysqld] 添加上即可​

​​解决方法​​

[mysqld]
……
basedir=/lm/mysql
datadir=/lm/mysql/data

[root@localhost bin]# /etc/init.d/mysqld start

Starting MySQL. SUCCESS!

​​或者 更改目录​​

mysql 报错2：

提示没有目录 就创建目录

提示没有权限 就赋予mysql用户权限

chown -R mysql.mysql /lm/mysql*
