1. 准备安装包：
[root@localhost ~]# ls
cmake-2.8.10.2.tar.gz mysql-5.5.30.tar.gz
2. 安装CMAKE：
tar -xzvf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./configure
make
make install
3. 安装MYSQL
yum install ncurses-devel
groupadd mysql
useradd -r -g mysql mysql
mkdir -p /u01/mysql/data
mkdir -p /u01/mysql/logs/mysql
mkdir -p /u01/mysql/data/log
tar -xzvf mysql-5.5.30.tar.gz
cmake -DCMAKE_INSTALL_PREFIX=/u01/mysql -DMYSQL_DATADIR=/u01/mysql/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1
make
make install
cd /u01
chown -R root:mysql mysql
chown -R mysql:mysql mysql
cd mysql
cp support-files/my-medium.cnf /etc/my.cnf
4. 初始化DB：
[root@localhost mysql]# scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql
Installing MySQL system tables...
140425 12:08:57 mysqld_safe mysqld from pid file /u01/mysql/data/localhost.localdomain.pid ended
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
./bin/mysqladmin -u root password 'new-password'
./bin/mysqladmin -u root -h 127.0.0.1 password 'new-password'
Alternatively you can run:
./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd ./mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!
[1]+ Done ./mysqld_safe (wd: /u01/mysql/bin)
5. 修改ROOT密码：
[root@localhost ~]# mysqld_safe --defaults-file=/etc/my.cnf &
140426 12:12:43 mysqld_safe Logging to '/u01/mysql/logs/mysql/error3306.log'.
140426 12:12:44 mysqld_safe Starting mysqld daemon with databases from /u01/mysql/data
