ubuntu上用源码进行一键安装mysql

首先卸载原有的mysql：

首先查看自己的mysql有哪些依赖

#dpkg --list|grep mysql

先卸载

#sudo apt-get remove mysql-common

#sudo apt-get autoremove --purge mysql-server-5.0

再用dpkg --list|grep mysql查看，还剩什么就卸载什么

#dpkg --list|grep mysql

最后清楚残留数据：

#dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

#---------------------------------------------------------------------------------------------------------->>

接下来以root身份安装mysql，同时，需要下载带有boost的mysql源码，

选择带有boost的源码包

将源码包下载到/usr/local/src/之后，进入/usr/local/src/，然后将下面的脚本mysql.sh也放在/usr/local/src/目录下面，然后执行即可：

# sh mysql.sh

接着需要配置/etc/my.cnf文件，配置如下：

[client]
port=
default-character-set=utf8
socket=/tmp/mysql.sock
[mysqld]
#skip-grant-tables
basedir=/usr/local/mysql
port=
datadir=/usr/local/mysql/data/db_file
socket=/tmp/mysql.sock
max_connections=
default-storage-engine=INNODB
max_allowed_packet=16M
innodb_buffer_pool_size=128M
explicit_defaults_for_timestamp=true
[mysqld_safe]
log_error=/usr/local/mysql/data/error.log
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

然后到/usr/local/mysql/bin目录下执行初始化操作：

1  ./mysqld --defaults-file=/etc/my.cnf

结果如下：

 root@mi-OptiPlex-:/usr/local/mysql/bin# ./mysqld --defaults-file=/etc/my.cnf  --initialize --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/db_file/  --user=mysql
 --02T06::.153186Z  [Warning] InnoDB: New log files created, LSN=
 --02T06::.485746Z  [Warning] InnoDB: Creating foreign key constraint system tables.

 --02T06::.722060Z  [Note] A temporary password is generated for root@localhost: 1SjpD:qZ0VrN

初始化注意事项：

　　　　　　　　1.如果出现如下信息：unknown variable 'defaults-file=/etc/my.cnf'，请保证--defaults-file配置选项在最前面。

　　　　　　　　2.初始化最后一行是root用户密码(root@localhost: ,5j1Qj_LLAek)如图：

 

# service mysql-server start

#service mysql-server restart

#service mysql-server stop

# mysql -u root -p
