第4部分:PHP的优化
优化一:将PHP由之前的xcache换成eaccelerator
1 安装
wget http://bart.eaccelerator.net/source/0.9.5.3/eaccelerator-0.9.5.3.tar.bz2
tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php5/bin/php-config
make
make install
注:PHP路径以安装为准!
2 配置
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php5/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\n#' /etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /etc/php.ini
配置eAccelerator加速PHP：
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /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/php5/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"
eaccelerator.shm_size="128"
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="300"
eaccelerator.shm_prune_period="120"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
优化二:联系开发重新编译php减少php的模块.以减少php进程所占用内存数.这块尽管影响不大,但也有一定的作用.编译前也可以参照nginx的编译器优化方式安装.
第5部分:测试并启动nginx
ulimit -SHn 51200
/usr/local/webserver/nginx/sbin/nginx -t
/usr/local/webserver/nginx/sbin/nginx
第6部分:nginx日志切割脚本
#!/bin/bash
# This script run at 00:00
# The Nginx logs path
logs_path="/exp/nginxlogs/"
mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}bbs.linuxtone_access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/bbs.linuxtone_access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`
crontab -e
00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
