1、MySQL单双实例安装

【单实例安装】
说明：即只提供一个服务，一个端口
sed -i 2s/localhost.localdomain/mysql/ /etc/sysconfig/network
hostname mysql
yum -y install ncurses-devel gcc gcc-c++
useradd mysql -s /sbin/nologin -M
tar xf cmake-2.8.8.tar.gz
cd cmake-2.8.8
./configure
gmake
gmake install
cd ..
tar xf mysql-5.5.32.tar.gz
cd mysql-5.5.32
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
-DWITH_ZLIB=bundled \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH-DEBUG=0
make && make install
cp support-files/my-small.cnf /etc/my.cnf
ln -s /usr/local/mysql/bin/* /usr/local/sbin
chmod -R 1777 /tmp
chown -R mysql:mysql /usr/local/mysql
cd /usr/local/mysql/scripts/
./mysql_install_db --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql
cp /opt/mysql-5.5.32/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
service mysqld start
chkconfig mysqld on
mysql -e "delete from mysql.user where user='';"
mysql -e "delete from mysql.user where host='localhost.localdomain';"
mysql -e "delete from mysql.user where host='::1';"
mysql -e "drop database test;"
mysqladmin -u root password "wsyht123"

【多实例安装】
说明：多实例，指多个端口，多个MySQL提供服务
sed -i 2s/localhost.localdomain/mysql/ /etc/sysconfig/network
hostname mysql
yum -y install ncurses-devel gcc gcc-c++ libaio-devel
useradd mysql -s /sbin/nologin -M
tar xf cmake-2.8.8.tar.gz
cd cmake-2.8.8
./configure
gmake
gmake install
cd ..
tar xf mysql-5.5.32.tar.gz
cd mysql-5.5.32
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \

-DWITH-DEBUG=0
make && make install
ln -s /usr/local/mysql/bin/* /usr/local/sbin
chmod 700 /opt/mysql
mkdir -p /data/{3306,3307,3308}
