mysql5.5编译安装

cmake 的解压

cd cmake-2.8.8

./configure 

gmake(注意这里是gmake)

gmake install


安装好之后,还需要安装一些依赖

yum install ncurses-devel -y



tar xf mysql-5.5.32.tar.gz 


cd mysql-5.5.32


groupadd mysql

useradd mysql -s /sbin/nologin -M -g mysql



cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \

-DMYSQL_DATADIR=/application/mysql-5.5.32/data \

-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/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_FAST_MUTEXES=1 \

-DWITH_ZLIB=bundled \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_READLINE=1 \

-DWITH_EMBEDDED_SERVER=1 \

-DWITH_DEBUG=0





make && make install

  


ln -s /application/mysql-5.5.32/ /application/mysql


以上代表安装成功,

下面的是初使化

cp mysql-5.5.32/support-files/my-small.cnf /etc/my.cnf 

会显示是否覆盖,选择是

这里选择的文件是my-small.cnf,因是测试环境,生产环境可以根据硬件选择,例如:my-innodb-heavy-4G.cnf



然后配置环境变量,建议最好配

echo 'export PATH=/application/mysql/bin:$PATH' >> /etc/profile


tail -1 /etc/profile

source /etc/profile

echo $PATH



下面是初始化数据文件

chown -R mysql.mysql /application/mysql/data

chmod -R 1777/tmp/

cd /application/mysql/scripts/

./mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql


然后看是否有两个OK


然后再设置一下启动脚本

cp support-files/mysql.server /etc/init.d/mysqld

加个权限

chmod  +x /etc/init.d/mysqld

然后启动mysql 

/etc/init.d/mysqld start



*****登录mysql 故障解决

mysql

ERROR 1045 (28000):Access denied for user 'root'@'localhost'  (using password :NO)

问题解决:

#pkill mysqld

#lsof -i :3306

#rm -rf /application/mysql/data/*

#/application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql

解决!




登录成功后,查看哪些空登录。

select user,host from mysql.user;

删除那些空登录的。

delete from mysql.user where user='';

删除那些ipv6的

delete from mysql.user where host = '::1';

删除test库

drop database test; 

show databases; 


quit

退出,为mysql 增加密码。


/application/mysql//bin/mysqladmin -u root password 'liucong008'



设置开机启动

 chkconfig mysqld on

 chkconfig mysqld  --list
