Install the required MySQL software package through Ubuntu Compilation

1. Ubuntu install MySQL Required Software Package sudoapt-getinstallbinutilscppfetchmailflexgcclibarchive-zip-perllibc6-devlibcompre

1. Ubuntu install MySQL required package sudo apt-get install binutils cpp fetchmail flex gcc libarchive-zip-perl libc6-dev libcompre

1. Install the required MySQL software package in Ubuntu

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-modules unzip zip zlib1g-dev autoconf automake1.9 libtool bison autotools-dev g ++ build-essential

2. Install libncurses5-dev
Sudo apt-get install libncurses5-dev

When the software is compiled and installed through the source code, the following error occurs:

Checking for termcap functions library... Configure: error: No curses/termcap library found

Install the libncurses5-dev library.

3. Install MySQL

Mysql uses UTF-8 as the default encoding:
Groupadd mysql
Useradd-g 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
Enter the code:

[Client]
Default-character-set = utf8
Port = 3306
Socket =/tmp/mysql. sock

[Mysql]
Prompt = "(\ u: Molutran's MySQL Server :) [\ d]>"

4. Add write permission to the MySQL installation directory and change the group

Chmod + w/usr/local/mysql
Chown-R mysql: mysql/usr/local/mysql

5. Modify the root user password

Mysql> use mysql
Mysql> UPDATE user SET password = PASSWORD ('new _ password') WHERE user = 'root ';
Mysql> flush privileges;
Mysql> exit
