linux安装mysql问题

[yanglinxinghun]

我安装的mysql rpm包
安装mysql后启动mysql提示Starting MySQL. ERROR! Manager of pid-file quit without updating file.错误

我的mysql错误日志是

请问各位大侠这个问题怎么回事如何解决？？

已经告诉你了，缺少libstdc++.so.6这个文件，你安装系统的时候，系统的库文件没有安装全

缺少rpm包依赖！不妨试试安装源码包，到网上去下一个msql.tar.gz格式的源码包！


安装步骤如下：
[root@localhost root]#tar －xvf mysql-3.23.53.tar.gz
解压之后进入该文件夹：

[root@localhost root]#cd mysql
建立mysql用户和mysql组：

[root@localhost root]#groupadd mysql
[root@localhost root]#useradd –g mysql mysql
在这里建立一个mysql用户和组的目的是：要给mysql数据库一个启动的用户和组，这样可以不用以管理员（root）的身份去启动mysql，大大的提高了服务器的安全。
然后给mysql用户设置一个密码：
[root@localhost root]#passwd mysql
然后编译mysql，目的是为mysql设置一些参数选项：


[root@localhost root]#
./configure --prefix=/usr/tools/mysql --enable-assembler --with-mysqld-ldflags=-all-static --with-charset=utf8 --with-collation=utf8_unicode_ci


开始执行make：

[root@localhost root]#make
[root@localhost root]#make install

完成后进入scripts目录执行：

[root@localhost root]#./scripts/mysql_install_db
[root@localhost root]#cp support-files/my-medium.cnf /etc/my.cnf
[root@localhost root]#cp support-files/mysql.server /etc/init.d/mysqld

完成配置文件和启动文件的复制后，执行修改文件权限的命令：
[root@localhost root]#chmod 700 /etc/init.d/mysqld
[root@localhost root]#cd /opt/mysql
[root@localhost root]#chown -R root mysql
[root@localhost root]#chown -R mysql mysql/var
[root@localhost root]#chgrp -R mysql mysql

权限修改完毕后，复制启动文件，修改启动选项：
[root@localhost root]#cp mysqld mysqld.old
[root@localhost root]#strip mysqld
[root@localhost root]#chkconfig --add mysqld
[root@localhost root]#chkconfig --level 345 mysqld on
[root@localhost root]#service mysqld start

装系统的时候没安gcc,建议再装一下
