  Apache源于NCSAhttpd服务器,经过多次修改,成为世界上最流行的Web服务器软件之一。Apache取自“a patchy server”的读音,意思是充满补丁的服务器,因为它是自由软件,所以不断有人来为它开发新的功能、新的特性、修改原来的缺陷。Apache的特点是简单、速度快、性能稳定,并可做代理服务器来使用。
  apache随机启动
  cp /usr/local/apache/bin/apachectl /etc/rc.d/init.d/apached
  chmod x /etc/rc.d/init.d/apached
  ln -s /etc/rc.d/init.d/apached /etc/rc3.d/S100apache
  ln -s /etc/rc.d/init.d/apached /etc/rc0.d/K100apache
  mysql随机启动
  默认配置
  cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
  chmod x /etc/rc.d/init.d/mysql
  ln -s /etc/rc.d/init.d/mysql /etc/rc3.d/S100mysql
  ln -s /etc/rc.d/init.d/mysql /etc/rc0.d/K100mysql
  非默认安装 比如配置在/opt/mysql_server中 创建启动文件/opt/mysql_server/start.sh
  #!/bin/sh
  rundir="/opt/mysql_server".
  echo $rundir.
  /usr/local/mysql/bin/mysqld_safe --defaults-file="$rundir"/my.cnf --pid-file="$rundir"/mysql.pid --datadir="$rundir"/data --socket="$rundir"/mysql.sock --user=mysql --log-error="$rundir"/error.log --log-slow-queries="$rundir"/slow_query.log&.
  创建停止文件/opt/mysql_server/stop.sh
  #!/bin/sh
  rundir="/opt/mysql_server".
  echo $rundir.
  /usr/local/mysql/bin/mysqladmin -uroot -pctech --socket="$rundir"/mysql.sock shutdown
  创建配置文件my.cnf
  [mysqld]
  port = 8211
  skip-locking
  skip-innodb
  skip-name-resolve
  set-variable = back_log=600
  set-variable = key_buffer=4M
  set-variable = max_allowed_packet=2M
  set-variable = table_cache=512
  set-variable = sort_buffer=16M
  set-variable = record_buffer=8M
  set-variable = thread_cache=32
  set-variable = long_query_time=200
  set-variable = wait_timeout=200
  query_cache_size = 16M
  query_cache_type = 1
  query_cache_limit = 4M
  # Try number of CPUs*2 for thread_concurrency
  set-variable = thread_concurrency=8
  set-variable = myisam_sort_buffer_size=2M
  set-variable = max_connections=600
  set-variable = max_connect_errors=600
  #log-bin
  tmpdir = /tmp/
  [client]
  socket=/opt/mysql_server/mysql.sock
  创建服务文件/opt/mysql_server/mysql_self_server
  #!/bin/sh
  ARGV="$@"
  ERROR=0
  case $ARGV in
  start)
  /opt/mysql_server/start.sh
  ERROR=$?
  ..
  stop)
  /opt/mysql_server/stop.sh
  ..
  *)
  ERROR = "error arguments"
  esac
  exit $ERROR
  最后
  cp /opt/mysql_server/mysql_self_server /etc/rc.d/init.d/mysql_self_server
  chmod x /etc/rc.d/init.d/mysql_self_server
  ln -s /etc/rc.d/init.d/mysql_self_server /etc/rc3.d/S100mysql_self_server
  ln -s /etc/rc.d/init.d/mysql_self_server /etc/rc0.d/K100mysql_self_server
