cd mcrypt-2.6.8/ /sbin/ldconfig ./configure make make install cd ../2.编译安装MySQL 5.5.3-m3
(1)/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql 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 ../(2) 创建MySQL数据库存放目录
mkdir -p /media/raid10/mysql/3306/data/ mkdir -p /media/raid10/mysql/3306/binlog/ mkdir -p /media/raid10/mysql/3306/relaylog/ chown -R mysql:mysql /media/raid10/mysql/注意:因为要存放数据库文件,所以我把 这些文件,存放在 RAID10的设备上
实现 软RAID10,可以查看之前的文章共三篇 http://blog.csdn.net/longxibendi/archive/2011/04/20/6336912.aspx http://blog.csdn.net/longxibendi/archive/2011/04/20/6336921.aspx http://blog.csdn.net/longxibendi/archive/2011/04/20/6336947.aspx(3).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=/media/raid10/mysql/3306/data --user=mysql(4).创建my.cnf配置文件
vi /media/raid10/mysql/3306/my.cnf[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 = /media/raid10/mysql/3306/data log-error = /media/raid10/mysql/3306/mysql_error.log pid-file = /media/raid10/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 = 16M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 300 #thread_concurrency = 8 query_cache_size = 20M query_cache_limit = 2M query_cache_min_res_unit = 2k default-storage-engine = MyISAM thread_stack = 192K transaction_isolation = READ-COMMITTED tmp_table_size = 20M max_heap_table_size = 20M long_query_time = 3 log-slave-updates log-bin = /media/raid10/mysql/3306/binlog/binlog binlog_cache_size = 4M binlog_format = MIXED max_binlog_cache_size = 8M max_binlog_size = 20M relay-log-index = /media/raid10/mysql/3306/relaylog/relaylog relay-log-info-file = /media/raid10/mysql/3306/relaylog/relaylog relay-log = /media/raid10/mysql/3306/relaylog/relaylog expire_logs_days = 30 key_buffer_size = 10M read_buffer_size = 1M read_rnd_buffer_size = 6M bulk_insert_buffer_size = 4M myisam_sort_buffer_size = 8M myisam_max_sort_file_size = 20M myisam_repair_threads = 1 myisam_recoverinteractive_timeout = 120
wait_timeout = 120skip-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 = 3306server-id = 1
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 20M innodb_data_file_path = ibdata1:56M: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 = 20M 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 = /media/raid10/mysql/3306/slow.log
#long_query_time = 10[mysqldump]
quick max_allowed_packet = 32M注意:由于用的虚拟机,只分配了512M内存,所以,相应的参数配置的很小。根据自己需求配置
(5).创建一个shell脚本,管理MySQL
vi /media/raid10/mysql/3306/mysql 输入以下内容(这里的用户名是admin 密码是 12345678 ,接下来会创建这个用户并授权)#!/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(6).赋予shell脚本 mysql 执行权限
chmod +x /media/raid10/mysql/3306/mysql
(7).启动MySQL
/media/raid10/mysql/3306/mysql start
(8).通过以下命令登录管理MySQL服务器(提示输入密码直接回车,这是用root登录的)
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
(9).输入以下SQL语句,用于创建一个具有root权限的用户 ,用户名是 上面提到的 admin 密码 是 12345678
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';因为接下来要安装wordpress,所以最好再加一条
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'www.linuxidc.com' IDENTIFIED BY '12345678';
注意:
这里的 www.linuxidc.com 是允许 连接 MySQL服务器的客户端IP地址 ; *.* 表示 所有 库和所有表 比如 blog.wordpress 表示 blog库的wordpress表最后再加上
flush privileges ;
(10).停止 MySQL (可选)
/media/raid10/mysql/3306/mysql stop或者用 root 停止
3.编译安装PHP(FastCGI模式)
tar zxvf php-5.2.14.tar.gz gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1 cd php-5.2.14/ ./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap make ZEND_EXTRA_LIBS='-liconv' make install cp php.ini-dist /usr/local/webserver/php/etc/php.ini cd ../4.编译安装PHP5扩展模块
tar zxvf memcache-2.2.5.tgz cd memcache-2.2.5/ /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config make make installtar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/ /usr/local/webserver/php/bin/phpize ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config make make install cd ../tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/ /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql make make install cd ../tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/ ./configure make make install cd ../tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/ /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config make make install cd ../5.修改php.ini文件
手工修改:查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/" 并在此行后增加以下几行,然后保存: extension = "memcache.so" extension = "pdo_mysql.so" extension = "imagick.so"再查找output_buffering = Off
修改为output_buffering = On再查找; cgi.fix_pathinfo=0
修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。 自动修改:若嫌手工修改麻烦,可执行以下shell命令,自动完成对php.ini文件的修改: sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\n#' /usr/local/webserver/php/etc/php.ini sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini6.配置eAccelerator加速PHP:
mkdir -p /usr/local/webserver/eaccelerator_cache vi /usr/local/webserver/php/etc/php.ini按shift+g键跳到配置文件的最末尾,加上以下配置信息:
[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so" eaccelerator.shm_size="64" eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="3600" eaccelerator.shm_prune_period="3600" eaccelerator.shm_only="0" eaccelerator.compress="1" eaccelerator.compress_level="9"7.创建www用户和组,以及供blog虚拟主机使用的目录:
/usr/sbin/groupadd www /usr/sbin/useradd -g www www mkdir -p /media/raid10/htdocs/blog chmod +w /media/raid10/htdocs/blog chown -R www:www /media/raid10/htdocs/blog mkdir -p /media/raid10/htdocs/www chmod +w /media/raid10/htdocs/www chown -R www:www /media/raid10/htdocs/www8.创建php-fpm配置文件(php-fpm是为PHP打的一个FastCGI管理补丁,可以平滑变更php.ini配置而无需重启php-cgi):
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件: rm -f /usr/local/webserver/php/etc/php-fpm.conf vi /usr/local/webserver/php/etc/php-fpm.conf输入以下内容(如果您安装 Nginx + PHP 用于程序调试,请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>,以便显示PHP错误信息,否则,Nginx 会报状态为500的空白错误页):

</configuration>
9.启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
ulimit -SHn 65535 /usr/local/webserver/php/sbin/php-fpm start注意:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包 括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件 使用reload。
四.安装Nginx 0.8.46
1.安装Nginx所需的pcre库:
tar zxvf pcre-8.10.tar.gz
cd pcre-8.10/ ./configure make && make install cd ../2.安装Nginx
tar zxvf nginx-0.8.46.tar.gz
3.创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs chown -R www:www /data1/logs4.创建Nginx配置文件
(1)在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件: rm -f /usr/local/webserver/nginx/conf/nginx.conf vi /usr/local/webserver/nginx/conf/nginx.conf输入以下内容:
user www www;worker_processes 8;
error_log /media/raid10/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this pro

(2).在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件: vi /usr/local/webserver/nginx/conf/fcgi.conf输入以下内容:
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol;fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name;# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;5.启动Nginx
ulimit -SHn 65535 /usr/local/webserver/nginx/sbin/nginx五.配置开机自动启动Nginx + PHP
vi /etc/rc.local在末尾增加以下内容:
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start /usr/local/webserver/nginx/sbin/nginx六.优化Linux内核参数
vi /etc/sysctl.conf# http://blog.csdn.net/longxibendi start
net.ipv4.tcp_max_syn_backlog = 65536 net.core.netdev_max_backlog = 32768 net.core.somaxconn = 32768net.core.wmem_default = 8388608
net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1 net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120 net.ipv4.ip_local_port_range = 1024 65535#http://blog.csdn.net/longxibendi end
使配置立即生效:
/sbin/sysctl -p七.在不停止Nginx服务的情况下平滑变更Nginx配置
1.修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确: /usr/local/webserver/nginx/sbin/nginx -t如果屏幕显示以下两行信息,说明配置文件正确:
the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok2.平滑重启:
(1)对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可: /usr/local/webserver/nginx/sbin/nginx -s reload (2)对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号: ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'屏幕显示的即为Nginx主进程号,例如:
6302 这时,执行以下命令即可使修改过的Nginx配置文件生效: kill -HUP 6302或者无需这么麻烦,找到Nginx的Pid文件:
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`或者
ps -ef | grep nginx | grep -v grep | xargs kill {}\;八.编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh输入以下内容:
引用 #!/bin/bash # This script run at 00:00# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid` 2、设置crontab,每天凌晨00:00切割nginx访问日志 crontab -e输入以下内容:
引用 00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh 九.安装 wordpress (1)下载 cd /home/root/data1 wget http://cn.wordpress.org/wordpress-3.1.1-zh_CN.tar.gz(2)解压 、赋权
tar zxvf wordpress-3.1.1-zh_CN.tar.gz -C /media/raid10/htdocs/blog/ chmod 777 -R /media/raid10/htdocs/blog/(3)创建数据库
/usr/local/webserver/mysql/bin/mysql -u admin -p -S /tmp/mysql.sock (注意密码是 12345678) MySQL>create database blog; MySQL>flush privileges;(4)修改 wp-config-sample.php
mv /media/raid10/htdocs/blog/wordpress/wp-config-sample.php /media/raid10/htdocs/blog/wordpress/wp-config.php vi /media/raid10/htdocs/blog/wordpress/wp-config.php 修改数据库名,用户,密码,数据库IP 比如我的修改后的文件部分内容是// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
/** WordPress 数据库的名称 */ define('DB_NAME', 'blog');/** MySQL 数据库用户名 */
define('DB_USER', 'admin');/** MySQL 数据库密码 */
define('DB_PASSWORD', '12345678');/** MySQL 主机 */
define('DB_HOST', 'www.linuxidc.com');注意:这里的DB_HOST对应的IP是,安装数据库的系统IP
(5)安装,运行 install.php
http://www.linuxidc.com/wordpress/install.php 或者 http://www.linuxidc.com/wordpress/wp-admin/install.php根据前面设置的用户名和密码安装即可
然后就可以访问 http://www.linuxidc.com/wordpress/ 了,
注意 : 如果想让非本机用户访问 需要打开防火墙 http服务 。默认只允许 SSH服务
