linux装mysql初始化失败

启动这个试试看

/mysql/bin/mysqld_safe &

试试看我整理的笔记

1. 安装mysql

mysql-5.0.41-linux-i686-glibc23.tar.gz 由于mysql是二进制包。所以还是比较方便的。

直接解压。然后移动。

mv mysql-5.0.41-linux-x86_64-glibc23 /usr/local/mysql

cd /usr/local/mysql

groupadd mysql

useradd -g mysql mysql

chown -R mysql .

chgrp -R mysql .

chown -R root .

./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/home/www/mysql/data

cp /usr/local/mysql/support-files/my-huge.cnf /etc/my.cnf

cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld

chmod 755 /etc/rc.d/init.d/mysqld

chkconfig –add mysqld

chkconfig --level 3 mysqld on

mv /usr/local/mysql/data /home/www/mysql

chown -R mysql:mysql /home/www/mysql

编辑/etc/my.cnf

在 [mysqld] 段增加

datadir = /home/www/mysql

skip-innodb

wait-timeout = 10

max_connections = 512

max_connect_errors = 10000000

在 [mysqld] 段修改

max_allowed_packet = 16M

thread_cache_size = CPU个数*2

将 log-bin 注释

service mysqld start

bin/mysqladmin -u root -p

这和两个系统变量有关，lc_messages_dir and lc_messages, 正常默认是没有问题。这里我们显式指定一下。重新初始化，如下：

[mysql@gebiji.com mysql]$bin/mysqld --initialize --user=mysql --basedir=/mysql/mysql/ --datadir=/mysql/data/ --lc_messages_dir=/mysql/mysql/share --lc_messages=en_US

lc_messages_dir，lc_messages分别用于指定lc messages的位置和语言，执行上面的命令后，日志输出如下：

2016-04 06T06:28:53.750837Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

[mysql@gebiji.com mysql]$

这样应该就没有问题了。
