已经是相对完整的 Linux 略过此步骤

下载程序源码包

创建目录存放源码包，此目录还要用于存放 mysql 数据库和作为程序空间使用

mkdir -p /data0/software cd /data0/software

下载程序源码包

wget http://nginx.org/download/nginx-1.2.0.tar.gz wget http://cn2.php.net/get/php-5.4.1.tar.gz/from/this/mirror wget http://blog.s135.com/soft/linux/nginx_php/mysql/mysql-5.5.3-m3.tar.gz

编译安装 MySQL

新建运行 MySQL 的用户

/usr/sbin/groupadd mysql /usr/sbin/useradd -g mysql mysql

编译安装 MySQL

tar zxvf mysql-5.5.3-m3.tar.gz cd mysql-5.5.3-m3/ ./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg make && make install chmod +w /usr/local/webserver/mysql chown -R mysql:mysql /usr/local/webserver/mysql cd ../

创建 MySQL 数据库存放目录

mkdir -p /data0/mysql/3306/data/ mkdir -p /data0/mysql/3306/binlog/ mkdir -p /data0/mysql/3306/relaylog/ chown -R mysql:mysql /data0/mysql/

以 mysql 用户帐号的身份建立数据表

/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql

创建 my.cnf 配置文件

vi /data0/mysql/3306/my.cnf

输入以下内容：

[client] character-set-server = utf8 port = 3306 socket = /tmp/mysql.sock [mysqld] character-set-server = utf8 replicate-ignore-db = mysql replicate-ignore-db = test replicate-ignore-db = information_schema user = mysql port = 3306 socket = /tmp/mysql.sock basedir = /usr/local/webserver/mysql datadir = /data0/mysql/3306/data log-error = /data0/mysql/3306/mysql_error.log pid-file = /data0/mysql/3306/mysql.pid open_files_limit = 10240 back_log = 600 max_connections = 5000 max_connect_errors = 6000 table_cache = 614 external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 300 #thread_concurrency = 8 query_cache_size = 512M query_cache_limit = 2M query_cache_min_res_unit = 2k default-storage-engine = MyISAM thread_stack = 192K transaction_isolation = READ-COMMITTED tmp_table_size = 246M max_heap_table_size = 246M long_query_time = 3 log-slave-updates log-bin = /data0/mysql/3306/binlog/binlog binlog_cache_size = 4M binlog_format = MIXED max_binlog_cache_size = 8M max_binlog_size = 1G relay-log-index = /data0/mysql/3306/relaylog/relaylog relay-log-info-file = /data0/mysql/3306/relaylog/relaylog relay-log = /data0/mysql/3306/relaylog/relaylog expire_logs_days = 30 key_buffer_size = 256M read_buffer_size = 1M read_rnd_buffer_size = 16M bulk_insert_buffer_size = 64M myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 myisam_recover interactive_timeout = 120 wait_timeout = 120 skip-name-resolve #master-connect-retry = 10 slave-skip-errors = 1032,1062,126,1114,1146,1048,1396 #master-host = 192.168.1.2 #master-user = username #master-password = password #master-port = 3306 server-id = 1 innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 512M innodb_data_file_path = ibdata1:256M:autoextend innodb_file_io_threads = 4 innodb_thread_concurrency = 8 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 16M innodb_log_file_size = 128M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 innodb_file_per_table = 0 #log-slow-queries = /data0/mysql/3306/slow.log #long_query_time = 10 [mysqldump] quick max_allowed_packet = 32M

创建管理MySQL数据库的shell脚本

vi /data0/mysql/3306/mysql

输入以下内容（这里的用户名admin和密码12345678接下来的步骤会创建）

#!/bin/sh mysql_port=3306 mysql_username = "admin" mysql_password = "12345678" function_start_mysql() { printf "Starting MySQL...n" /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null & } function_stop_mysql() { printf "Stoping MySQL...n" /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown } function_restart_mysql() { printf "Restarting MySQL...n" function_stop_mysql sleep 5 function_start_mysql } function_kill_mysql() { kill -9 $(ps -ef | grep \'bin/mysqld_safe\' | grep ${mysql_port} | awk \'{printf $2}\') kill -9 $(ps -ef | grep \'libexec/mysqld\' | grep ${mysql_port} | awk \'{printf $2}\') } if [ "$1" = "start" ]; then function_start_mysql elif [ "$1" = "stop" ]; then function_stop_mysql elif [ "$1" = "restart" ]; then function_restart_mysql elif [ "$1" = "kill" ]; then function_kill_mysql else printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}n" fi

赋予shell脚本可执行权限

chmod +x /data0/mysql/3306/mysql

启动MySQL

/data0/mysql/3306/mysql start

通过命令行登录管理MySQL服务器（提示输入密码时直接回车）

/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）

GRANT ALL PRIVILEGES ON *.* TO \'admin\'@\'localhost\' IDENTIFIED BY \'12345678\'; GRANT ALL PRIVILEGES ON *.* TO \'admin\'@\'127.0.0.1\' IDENTIFIED BY \'12345678\';

有时候编译无法生成 /tmp/mysql.sock ?
要等 mysql 启动过后才会生成，有部分原因会导致无法生成。

编译安装PHP（FastCGI模式）
