1、创建相关目录用户
su – root
groupadd mysql
useradd -g mysql -p xifenfei -s /bin/bash -m mysql -d /opt/mysql
MYSQL_BASE=/opt/mysql
mkdir -p $MYSQL_BASE/product/5.5
mkdir -p $MYSQL_BASE/mysqldata
mkdir -p $MYSQL_BASE/mysqllog
mkdir -p /var/run/mysqld/
chmod -R 777 $MYSQL_BASE
chown -R mysql:mysql $MYSQL_BASE
chown -R mysql:mysql /var/run/mysqld

3、环境变量配置
export MYSQL_BASE=/opt/mysql
export basedir=$MYSQL_BASE/product/5.5
export datadir=$MYSQL_BASE/mysqldata
export LD_LIBRARY_PATH=$basedir/lib:/lib:/usr/lib:/usr/local/lib
export TMPDIR=/tmp
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH=$basedir:$basedir/bin:${PATH}:$LD_LIBRARY_PATH

4、调整mysql 用户系统限制(可选)
编辑文件:/etc/security/limits.conf 加入以下语句:
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
确认如下语句是否存在于/etc/pam.d/login,如果不存在请增加:
session required pam_limits.so
如果用户SHELL 用的是Bourne, Bash, 或者Korn shell 修改/etc/profile,并增加如
下内容。(在SuSe 操作系统上,则需要修改/etc/profile.local):
if [ $USER = "mysql" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

5、安装数据库
5.1)解压数据库至/opt/mysql/product/5.5中
5.2)安装数据
[mysql@localhost ~]$ cd product/5.5/scripts/
[mysql@localhost scripts]$ ./mysql_install_db –basedir=$basedir –datadir=$datadir –user=mysql

5.3)设置my.cnf参数
vi /etc/my.cnf

[mysqladmin]
socket =/var/run/mysqld/mysqld.sock
[client]
port = 3306
socket =/var/run/mysqld/mysqld.sock
[mysqld]
port = 3306
socket = /var/run/mysqld/mysqld.sock
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
basedir = /opt/mysql/product/5.5
datadir = /opt/mysql/mysqldata
skip-external-locking = 1
interactive_timeout = 1200
wait_timeout = 1200
character-set-server = utf8
back_log = 500
default_time_zone = '+08:00'
max_connections = 1000
max_connect_errors = 1000
connect_timeout = 300
table_open_cache = 100
max_allowed_packet = 16M
binlog_cache_size = 8M
max_heap_table_size = 64M
sort_buffer_size = 8M
join_buffer_size = 8M
thread_cache_size = 32
thread_concurrency = 16
query_cache_size = 0M
default-storage-engine = INNODB
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 64M
log-bin =/opt/mysql/mysqllog/mysqlbin
log-error=/opt/mysql/mysqllog/mysqld.err
expire_logs_days = 7
binlog_format = ROW
max_binlog_size = 300M
slow_query_log = 1
slow_query_log_file =/opt/mysql/mysqllog/mysqld-slow
long_query_time = 10
tmpdir = /tmp
server-id = 1
key_buffer_size = 8M
read_buffer_size = 1M
read_rnd_buffer_size = 1M
bulk_insert_buffer_size = 1M
myisam_sort_buffer_size = 128K
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2G
innodb_data_file_path = ibdata1:1024M:autoextend
innodb_autoextend_increment = 64
innodb_file_per_table = 1
innodb_data_home_dir = /opt/mysql/mysqldata
innodb_file_io_threads = 4
innodb_thread_concurrency = 16
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 8M
innodb_log_file_size = 512M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 40
innodb_lock_wait_timeout = 120
innodb_locks_unsafe_for_binlog = 1
innodb_autoinc_lock_mode = 2
skip-name-resolve
lower_case_table_names=1
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
auto-rehash
[myisamchk]
key_buffer_size = 512M
sort_buffer_size = 512M
read_buffer = 8M
write_buffer = 8M
[mysqlhotcopy]
interactive-timeout
[mysqld_safe]
open-files-limit = 8192

5.4)异常处理
5.4.1)直接通过mysqld_safe不能正常启动数据库
ln -s /opt/mysql/product/5.5 /usr/local/mysql
或者
ln -s /opt/mysql/product/5.5/bin/mysqld /usr/local/mysql/bin/mysqld

5.4.2)mysql_secure_installation不能正常执行
1)
执行:/opt/mysql/product/5.5/bin/mysql_secure_installation出现以下错误,解决方法(ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock)
Enter current password for root (enter for none):
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

2)
修改mysql_secure_installation 脚本的do_query 函数(推荐处理方法)
do_query() {
echo “$1″ >$command
#sed ‘s,^,> ,’ < $command # Debugging
# mysql --defaults-file=$config <$command ----此行修改如下:
mysql --defaults-extra-file=$config <$command
return $?
}

6、添加开机启动服务
修改mysql.server文件
basedir=/opt/mysql/product/5.5
datadir=/opt/mysql/mysqldata
[root@localhost ~]# cp /opt/mysql/product/5.5/support-files/mysql.server /etc/init.d/mysqld
[root@localhost ~]# chkconfig –add mysqld
[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]# chkconfig –list mysqld
mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
