Web服务之LNMMP架构及动静分离实现
2020-12-13 05:41
标签：lnmmp web服务 nginx 一、LNMMP LNMMP环境是Linux + Nginx + Memcached + MySQL + PhP，即LNMP + memcached。 二、工程拓扑 三、安装nginx服务器 四、安装MySQL服务器 1.安装 2.为数据库创建数据目录 3.新建用户以安全方式运行进程
4.初始化mysql 5.提供脚本
6.提供配文件 7.其他配置 8.启动服务 9.用户初始化
五、安装php服务器 1.解决开发环境和依赖关系 2.安装php 3.提供配置文件 4.为php-fpm提供脚本，并将其添加到服务列表 5.为php-fpm提供配置文件 6.编辑php-fpm配置文件 7.启动php-fpm 六、安装php加速器xcache 1.安装xcache 2.编辑配置文件，整合php + xcache 3.重启php-fpm 七、配置nginx 1.编辑/etc/nginx/nginx.conf,实现动静分离
2.编辑/etc/nginx/fastcgi_params 3.重载nginx 八、安装Memcached服务器 1.memcached特性 Memcached是一款开发工具，它既不是一个代码加速器，也不是数据库中间件。其设计哲学思想主要反映在如下方面： （1）简单key/value存储：服务器不关心数据本身的意义及结构，只要是可序列化数据即可。存储项由“键、过期时间、可选的标志及数据”四个部分组成； （2）功能的实现一半依赖于客户端，一半基于服务器端：客户负责发送存储项至服务器端、从服务端获取数据以及无法连接至服务器时采用相应的动作；服务端负责接收、存储数据，并负责数据项的超时过期； （3）各服务器间彼此无视：不在服务器间进行数据同步； （4）O(1)的执行效率 （5）清理超期数据：默认情况下，Memcached是一个LRU缓存，同时，它按事先预订的时长清理超期数据；但事实上，memcached不会删除任何已缓存数据，只是在其过期之后不再为客户所见；而且，memcached也不会真正按期限清理缓存，而仅是当get命令到达时检查其时长； 2.安装memcached a).部署开发环境，解决依赖关系 b).编译安装memcached c).为memcached提供启动脚本 d).添加memcached至服务列表 e).检查是否运行 九、安装php的memcached扩展 1.安装memcached扩展 2.编辑配置文件，整合php + memcached
3.重启php-fpm 4.对memcached功能进行测试，在网站目录中建立测试页面test.php 测试访问即可。 5.安装wordpress测试访问即可 十、安装memadmin-master查看memcached状态信息 1.解压即可使用 2.测试访问 www.hoo.com/memadmin-master 本文出自 “潇洒哥是先知” 博客，请务必保留此出处http://hoolee.blog.51cto.com/7934938/1413346 Web服务之LNMMP架构及动静分离实现,搜素材,soscw.com Web服务之LNMMP架构及动静分离实现 标签：lnmmp web服务 nginx 原文地址：http://hoolee.blog.51cto.com/7934938/1413346
1）部署开发环境
# yum -y install "Development tools" "Server Platform Development"
2）解决依赖 pcre-devel openssl-devel
# yum -y install pcre-devel openssl-devel
3) 设置用户
# groupadd -r nginx
# useradd -r -g nginx nginx
4）编译安装nginx-1.4.7
# tar xf nginx-1.4.7.tar.gz
# cd nginx-1.4.7
# ./configure --prefix=/usr --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=\ /var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock \--user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --http-client-body-temp-path=\ /var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ \ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre
# make && make install
5）检测配置文件语法
# /usr/sbin/nginx -t
6) 提供启动脚本
# vim /etc/rc.d/init.d/nginx
内容如下
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse # proxy and IMAP/POP3 proxy server
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`nginx -V 2>&1 | grep "configure arguments:" | sed ‘s/[^*]*--user=\([^ ]*\).*/\1/g‘ -`
options=`$nginx -V 2>&1 | grep ‘configure arguments:‘`
for opt in $options; do
if [ `echo $opt | grep ‘.*-temp-path‘` ]; then
value=`echo $opt | cut -d "=" -f 2`
if [ ! -d "$value" ]; then
# echo "creating" $value
mkdir -p $value && chown -R $user $value
fi
fi
done
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0
$1
;;
stop)
rh_status_q || exit 0

rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
7)为服务脚本赋予执行权限
# chmod +x /etc/rc.d/init.d/nginx
8）添加到系统服务并开机启动
# chkconfig --add nginx
# chkconfig nginx on
# chkconfig --list nigx
9) 设置nginx配置文件的语法高亮
# mkdir ./vim/syntax -pv
# cd .vim/syntax
# wget http://www.vim.org/scripts/download_script.php?src_id=19394
# cd .vim
# vim filetype.vim 内容如下
au BufRead,BufNewFile /etc/nginx/*,/usr/local/nginx/conf/* if &ft == ‘‘ | setfiletype nginx | endif
10）启动服务
# service nginx start
# ss -tnalp | grep nginx
# tar xf mysql-5.5.33-linux2.6-x86_64.tar.gz -C /usr/local# ln -sv /usr/local/mysql-5.5.33-linux2.6-x86_64 mysql 创建软连接，易于操作#mkdri -pv /mydata/data

#chown -R mysql:mysql /mydata/data//设置目录属主属组

# chown -R root .//设置当前目录所有文件属主为root
#cd /usr/local/mysql#cp support-files/mysql.server /etc/rc.d/init.d/mysqld//设置脚本mysqld
#chmod +x /etc/rc.d/init.d/mysqld//给脚本执行权限

# chkconfig mysqld on
#cd /usr/local/mysql#cp support-files/my-large.cnf /etc/my.cnf#vim /etc/my.cnfthread_concurrency = 2
//修改，并发线程数，bithread_concurrency的值为CPU个数乘以2
datadir = /mydata/data
#添加,mysql数据文件的存放路径：
# vim /etc/profile.d/mysqld.shexportPATH=/usr/local/mysql/bin:$PATH
# source /etc/profile.d/mysqld.sh#vim /etc/man.configMANPATH /usr/local/mysql/man//添加此行
# ln -sv /usr/local/mysql/include /usr/include/mysql//输出mysql的头文件至系统头文件路径/usr/include
# echo ‘/usr/local/mysql/lib‘ > /etc/ld.so.conf.d/mysql.conf//输出mysql的库文件给系统库
#ldconfig //重载系统库：# service mysqld start
# ss -tnl | grep 3306
#mysqlmysql> use mysqlmysql> selecthost,user,password from user;
mysql> DELETE FROM user WHERE user = ‘‘; //删除空用户
