 chmod +w /usr/local/mysql  
 chown -R mysql:mysql /usr/local/mysql   
 cd ../

 4.配置

  1> MYSQL配置

mkdir -p /var/mysql/  
mkdir -p /var/mysql/data/ 
mkdir -p /var/mysql/log/  
chown -R mysql:mysql /var/mysql/   
/usr/local/mysql/bin/mysql_install_db --defaults-file=/var/mysql/my.cnf --basedir=/usr/local/mysql --datadir=/var/mysql/data --user=mysql   
vi /var/mysql/my.cnf

   2> PHP配置

#[1]# vi /usr/local/php/etc/php.ini 

#[2]查找 extension_dir = "ext"（809行左右），在后面添加以下几行：
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/" 
extension=apc.so  
extension=imagick.so 
extension=memcache.so

#[3] 按shift+g键跳到配置文件的末尾，添加以下配置信息：
[APC]  
apc.enabled=1 
apc.ttl=7200 
apc.shm_size=32

#3> PHP-FPM配置 
cd /usr/local/php/etc/  
cp php-fpm.conf.default php-fpm.conf 
vi php-fpm.conf
 
#4> Nginx配置
cd /usr/local/nginx/conf/  
cp nginx.conf.default nginx.conf 
vi nginx.conf

 5.启动

 1> 启动MySQL 

##cp /usr/local/mysql/share/mysql/mysql.server /etc/rc.d/init.d/ 
##chkconfig --add mysql.server  #加入service和开机启动   
##/etc/rc.d/init.d/mysql.server start  #手动启动，下面设置root密码 
##上面方法启动不成功，下面的可以，不知道为什么，找了半天，找不到答案

/usr/local/mysql/bin/mysqld_safe --defaults-file=/var/mysql/my.cnf & #加入/etc/rc.d/rc.local中去，系统启动自动启动
/usr/local/mysql/bin/mysqladmin -u root password 'new-password'   
/usr/local/mysql/bin/mysqladmin -uroot -p shutdown  #手动关闭

  2> 启动memcached

chmod 0777 /var/run  #允许普通用户程序写入pid文件   
/usr/local/memcached/bin/memcached -p 11211 -d -u www -P /var/run/memcached.pid -m 64M -c 1024

参数含义：
-p memcached监听的TCP端口  
-l监听的ip地址，127.0.0.1是本机，当然也可以写上你的服务器IP，如：61.150.91.26，这是我服务器的IP地址，如果你需要多个服务器都能够读取这台memcached的缓存数据，那么就必须设定这个ip 
-d 以daemon方式运行，将程序放入后台  
-u memcached的运行用户，我设定的是nobody 
-P memcached的pid文件路径  
-m memcached可以使用的最大内存数量 
-c memcached同时可以接受的最大的连接数 如果你希望以socket方式来访问memcached，那么在启动的时候就必须去掉 -l和-p参数，并加上-s参数：     
-s memcached的socket文件路径

 

  3> 启动mephp-fpm和nginx

ulimit -SHn 65535  
/usr/local/php/sbin/php-fpm 
/usr/local/nginx/sbin/nginx
#以将这3条语句写入/etc/rc.local文件，这样每次开机就可以启动php-fpm和nginx了。

  4> 优化Linux内核参数

vi /etc/sysctl.conf

#在文件末尾增加以下内容：
# append 
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
