一、安装MySQL
1、1编译安装MySQL 5.5.3-m3
/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

chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ../
1、2本服务器上运行MySQL数据库
以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。
①、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/
②、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
1、3创建my.cnf配置文件：
vi /data0/mysql/3306/my.cnf
输入以下内容：

#log-slow-queries = /data0/mysql/3306/slow.log
#long_query_time = 10
[mysqldump]
quick
max_allowed_packet = 32M
1、4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
1、5赋予shell脚本可执行权限：
chmod +x /data0/mysql/3306/mysql
1、6启动MySQL：
/data0/mysql/3306/mysql start
1、7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
1、8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';

3、3创建Nginx日志目录
mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs
3、4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：
引用
user www www;
worker_processes 8;

}
server
{
listen 80;
server_name status.blog.s135.com;
location / {
stub_status on;

}
}
}
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：
引用
fastcgi_param GATEWAY_INTERFACE CGI/1.1;

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;
3、5启动Nginx
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx
四、配置开机自动启动Nginx + PHP
vi /etc/rc.local
在末尾增加以下内容：
引用
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
五、优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
引用
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768
net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1
net.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
使配置立即生效：
/sbin/sysctl -p
六、在不停止Nginx服务的情况下平滑变更Nginx配置
6、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 ok
the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully
6、2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`
七、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
八、常见错误
