Ubuntu 编译安装MySQL所需的软件包

1、Ubuntu安装MySQL所需软件包sudo apt-get install binutils cpp fetchmail flex gcc libarchive-zip-perl libc6-dev libcompre

1、Ubuntu安装MySQL所需软件包

sudo apt-get install binutils cpp fetchmail flex gcc libarchive-zip-perl libc6-dev libcompress-zlib-perl libdb4.3-dev libpcre3 libpopt-dev lynx m4 make ncftp nmap perl perl-modules unzip zip zlib1g-dev autoconf automake1.9 libtool bison autotools-dev g++ build-essential

2、安装libncurses5-dev
sudo apt-get install libncurses5-dev

通过源码编译安装软件时，，出现错误信息：

checking for termcap functions library… configure: error: No curses/termcap library found

安装libncurses5-dev库方可解决。

3、安装MySQL

mysql使用utf-8作为默认编码：
groupadd mysql
useradd -g mysql mysql
tar -zxvf mysql-5.0.45.tar.gz
cd mysql-5.0.45
./configure –prefix=/usr/local/mysql –with-charset=utf8 –with-collation=utf8_general_ci –with-extra-charsets=latin1
make
make install
vi my.cnf
输入代码：

[client]
default-character-set = utf8
port    = 3306
socket  = /tmp/mysql.sock

[mysql]
prompt="(\u:Molutran's MySQL Server:)[\d]> "
no-auto-rehash

[mysqld]
#default-character-set = utf8
user    = mysql
port    = 3306
socket  = /tmp/mysql.sock
basedir = /usr/local/mysql

max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 2M
join_buffer_size = 2M
thread_cache_size = 300
thread_concurrency = 8
query_cache_size = 32M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M

quick
max_allowed_packet = 32M

4、给MySQL安装目录加写权限并改变属组

chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql

5、附带修改root用户密码

mysql>use mysql
mysql>UPDATE user SET password=PASSWORD('new_password') WHERE user='root';
mysql>FLUSH PRIVILEGES;
mysql>exit
