SA手记 MySQL篇(1)安装

编译安装
添加mysql用户用户组:

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql

编译mysql:

#!/bin/sh
CFLAGS="-O3 -mpentiumpro -mstack-align-double"
CXX=gcc
CXXFLAGS="-O3 -mpentiumpro -mstack-align-double -felide-constructors -fno-exceptions -fno-rtti"
./configure --prefix=/home/admin/install/mysql \
   --with-charset=utf8 \
   --with-collation=utf8_general_ci \
   --enable-thread-safe-client \
   --with-extra-charsets=gbk,latin1 \
   --with-client-ldflags=-all-static \
   --with-mysqld-ldflags=-all-static \
   --enable-assembler \
   --with-unix-socket-path=/home/admin/install/mysql/var/mysql.sock \

安装:

make& make install

改变目录权限:

sudo chown -R mysql:mysql /home/admin/install/mysql/

初始化权限表等(root执行)

/home/admin/install/mysql/bin/mysql_install_db --user=mysql --basedir=/home/admin/install/mysql --datadir=/home/admin/install/mysql/data
