安裝mysql
yum install -y mysql-server?? ?

service mysqld start??? 啟動服務(wù)
service mysqld stop??? 關(guān)閉服務(wù)

修改/ect/my.cnf，如果文件不存在，直接創(chuàng)建，修改內(nèi)容如下：
[mysqld]
transaction-isolation=READ-COMMITTED
# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
# symbolic-links=0

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql

key_buffer????????????? = 16M
key_buffer_size???????? = 32M
max_allowed_packet????? = 32M
thread_stack??????????? = 256K
thread_cache_size?????? = 64
query_cache_limit?????? = 8M
query_cache_size??????? = 64M
query_cache_type??????? = 1

max_connections???????? = 550

# log_bin should be on a disk with enough free space
# NOTE: replace '/x/home/mysql/logs/binary' below with
#?????? an appropriate path for your system.
log_bin=/usr/local/mysql/mysql/logs/binary/mysql_binary_log

# For MySQL version 5.1.8 or later. Comment out binlog_format for older versions.
binlog_format?????????? = mixed

read_buffer_size = 2M
read_rnd_buffer_size = 16M
sort_buffer_size = 8M
join_buffer_size = 8M

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

創(chuàng)建目錄：
mkdir -p /usr/local/mysql/mysql/logs/binary/
chown mysql /usr/local/mysql/mysql/logs/binary/
sudo -u mysql touch /usr/local/mysql/mysql/logs/binary/mysql_binary_log.index


配置：/usr/bin/mysql_secure_installation
配置過程中，除了Disallow root login remotely？設(shè)置為n，其余全部設(shè)置為y。

啟動服務(wù)，登錄：mysql -uroot -p123456
創(chuàng)建數(shù)據(jù)庫：
create database amon DEFAULT CHARACTER SET utf8;
create database rman DEFAULT CHARACTER SET utf8;
create database metastore DEFAULT CHARACTER SET utf8;
create database sentry DEFAULT CHARACTER SET utf8;
create database nav DEFAULT CHARACTER SET utf8;
create database navms DEFAULT CHARACTER SET utf8;
create database scm DEFAULT CHARACTER SET utf8;

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH PRIVILEGES;

show engines，如果發(fā)現(xiàn)沒有InnoDB引擎，卸載mysql數(shù)據(jù)庫，從新安裝，沒有InnoDB引擎有可能是在my.cnf中配置了InnoDB相關(guān)參數(shù)，
去掉在my.cnf中所有有關(guān)InnoDB的參數(shù)配置，卸載步驟如下：

yum remove -y mysql-server?? ?
rm -rf /var/lib/mysql/ /usr/local/mysql/ /var/log/mysqld.log /var/run/mysqld.pid /etc/my.cnf

重新安裝，執(zhí)行以上步驟；

設(shè)置mysql開機啟動：
sudo /sbin/chkconfig mysqld on;
sudo /sbin/chkconfig --list mysqld;
