mysql 5.5.15 安装笔记
mysql-5.5.15 安装笔记
mysql 最新的版本都需要cmake编译安装，估计以后的版本也会采用这种方式，所以特地记录一下安装步骤及过程，以供参考。
注意：此安装是默认centos下已经安装了最新工具包，比如GNU make, GCC, Perl, libncurses5-dev，如果在编译安装过程中发现有缺失的工具包，先yum install 单独下载安装再继续即可。
下面这个脚本，就是为安装做准备的，删除centos默认安装的httpd等rpm包，并下载gcc等 devel.sh
#!/bin/sh
rpm -qa|grep httpd
rpm -e httpd
rpm -qa|grep mysql
rpm -e mysql
rpm -qa|grep php
rpm -e php
yum -y remove httpd
yum -y remove httpd*
yum -y remove mysql*
yum -y remove php*
yum -y install yum-fastestmirror
yum -y remove httpd
yum -y update
#Synchronization time
rm -rf /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
yum install -y ntp

一. Centos 用 wget 下载需要的软件，保存到目录 /usr/local/src/ 下
wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.15.tar.gz/from/http://mysql.he.net/
wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz
二. 安装 cmake
cd /root/soft
tar zxvf cmake-2.8.4.tar.gz
cd cmake-2.8.4
./bootstrap
make
make install
cd ../
三. 编译安装 MySQL 5.5.15
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar xvf mysql-5.5.15.tar.gz
cd mysql-5.5.15/
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/var/mysql/data \
-DMYSQL_USER=mysql
make
make install
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
ln -s /usr/local/mysql/lib/libmysqlclient.so.16 /usr/lib/libmysqlclient.so.16
mkdir -p /var/mysql/
mkdir -p /var/mysql/data/
mkdir -p /var/mysql/log/
chown -R mysql:mysql /var/mysql/
cd support-files/
cp my-large.cnf /var/mysql/my.cnf
cp mysql.server /etc/init.d/mysqld
四. 配置启动MySQL 5.5.15
1. 若有需要请先修改 mysql 的配置 my.cnf
vi /var/mysql/my.cnf
2. mysql 初始化安装
/usr/local/mysql/scripts/mysql_install_db \
--defaults-file=/var/mysql/my.cnf \
--basedir=/usr/local/mysql \
--datadir=/var/mysql/data \
--user=mysql
3. 将 mysql 加入开机启动
chmod +x /etc/init.d/mysqld
vi /etc/init.d/mysqld （编辑此文件，查找并修改以下变量内容：）
basedir=/usr/local/mysql
datadir=/var/mysql/data
chkconfig --add mysqld
chkconfig --level 345 mysqld on
4. 启动 mysql
service mysqld start
5. 安全配置
设置密码
#/usr/local/mysql/bin/mysqladmin -u root password 'newpassword'
设置远程访问密码，下一命令会关闭root远程访问。此命令可能失败， telnet root 3306 ，不通，正常，继续
#/usr/local/mysql/bin/mysqladmin -u root -h root password 'newpassword'
安全配置
#/usr/local/mysql/bin/mysql_secure_installation
6.重启服务，搞定
#/etc/init.d/mysqld restart
7.如果需要另外新加账户，进入mysql,授权即可
mysql> grant all privileges on testdb.* to my_user@'%' identified by '123345';
