Redhat下MySQL5.5.20安装配置

eqwytpicyq

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Redhat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。

一.
linux用wget下载需要的软件，保存到目录/usr/local/src下
　　wget ftp://mirror.switch.ch/mirror/mysql/Downloads/MySQL-5.5/mysql-5.5.20.tar.gz

wget http://www.cmake.org/files/v2.8/cmake-2.8.7.tar.gz
　　wget http://ftp.gnu.org/gnu/bison/bison-2.5.tar.gz
　　

　　二.安装cmake
cd /usr/local/src
tar zxvf
cmake-2.8.7.tar.gz
cd
cmake-2.8.7
./bootstrap
gmake
gmake install
cd ../

tar zxvf bison-2.5.tar.gz
cd bison-2.5

./configure
make
make install
cd ../

　　



三.编译安装MySQL 5.5.20

groupadd -g 1000 mysql

useradd -u 1000 -g mysql mysql

tar xvf mysql-5.5.20.tar.gz

cd mysql-5.5.20/


/usr/local/bin/cmake-DCMAKE_INSTALL_PREFIX=/opt/mysql \

-DMYSQL_UNIX_ADDR=/opt/mysql/mysql.sock \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_DEBUG=0 \

-DWITH_READLINE=1 \

-- Could NOT find Curses (missing:CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:82 (MESSAGE):
Curses library not found. Pleaseinstall appropriate package,
removeCMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name islibncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:117 (FIND_CURSES)
cmake/readline.cmake:213(MYSQL_USE_BUNDLED_READLINE)
CMakeLists.txt:250 (MYSQL_CHECK_READLINE)

yum install ncurses-devel
rm CMakeCache.txt
--这里重新开始做上面的cmake操作即可

make

make install

chmod +w /opt/mysql

chown -R mysql:mysql /opt/mysql

ln -s /opt/mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18

mkdir -p /opt/mysql/data

chown -R mysql:mysql /opt/mysql/data

mkdir -p /opt/mysql/log

chown -R mysql:mysql
/opt/mysql/log

cd support-files/


如果你的内存≤64m,复制my-small.cnf；内存64-128m,复制my-medium.cnf;内存128-512m,复制my-large.cnf;内存1-2g，复制my-huge.cnf;内存4g以上，复制my-innodb-heavy-4G.cnf
cp my-large.cnf /etc/my.cnf
cp mysql.server /etc/init.d/mysqld

四.配置启动MySQL
5.5.20

1.若有需要请先修改mysql的配置my.cnf

vi /etc/my.cnf 　　

[mysqld] 下添加
basedir = /opt/mysql
datadir = /opt/mysql/data



2.my.cnfmysql初始化安装

chmod +x/opt/mysql/scripts/mysql_install_db

/opt/mysql/scripts/mysql_install_db \

--defaults-file=/etc/my.cnf \

--basedir=/opt/mysql \

--datadir=/opt/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=/opt/mysql

datadir=/opt/mysql/data

chkconfig --add mysqld

chkconfig --level 345 mysqld on


4.启动mysql

service mysqld start


5.配置访问帐号root

/opt/mysql/bin/mysqladmin -uroot password zdsoft

/opt/mysql/bin/mysql -uroot -p

mysql>use mysql;

mysql>GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'zdsoft' with GRANT OPTION;

mysql>update user set password=password('zdsoft'); --所有用户都密码更新

mysql>FLUSH PRIVILEGES;

mysql>quit;
