centos下nginx+php7+mysql搭建web服务器

Nginx ("engine x") 是一个高性能的 HTTP 和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的，Igor 将源代码以类BSD许可证的形式发布。

在高并发连接的情况下，Nginx是Apache服务器不错的替代品。Nginx同时也可以作为7层负载均衡服务器来使用。在Nginx在性能方面，在网上有很多的介绍文章，在这里就不重复介绍了。

安装步骤：

（系统要求：Linux 3.0+ 内核，本文中的Linux操作系统为CentOS 7.0）

一、获取相关开源程序：

1、【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库（RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包，进行安装）：

sudo -s

LANG=C

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers cmake zip  libtool-ltdl libtool-ltdl-devel psmisc

2、【适用CentOS、RedHat及其它Linux操作系统】下载程序源码包：

大部份程序下载地址都在国外，下载可能比较慢，也可以去百度云盘下载

http://pan.baidu.com/s/1slm0FZR

二、安装PHP 7.0.12（FastCGI模式）

1、编译安装PHP 7.0.12所需的支持库：

tar zxvf libiconv-1.13.tar.gz

cd libiconv-1.13/

./configure --prefix=/usr/local

make

make install

cd ../

tar zxvf libmcrypt-2.5.8.tar.gz 

cd libmcrypt-2.5.8/

./configure

make

make install

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd ../../

tar zxvf mhash-0.9.9.9.tar.gz

cd mhash-0.9.9.9/

./configure

make

make install

cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la

ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so

ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4

ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz

cd mcrypt-2.6.8/

/sbin/ldconfig

./configure

make

make install

cd ../

三、编译安装mariadb（mariadb介绍请访问http://baike.baidu.com/item/mariaDB）

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql -s /sbin/nologin mysql

tar zxvf mariadb-10.1.18.tar.gz

cd mariadb-10.1.18/

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql/data -DWITH_INNOBASE_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLE_DEBUG_SYNC=1 -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=1 -DWITH_EMBEDDED_SERVER=1 -DWITH_EXTRA_CHARSETS=all -DWITH_LIBWRAP=1 -DWITH_READLINE=1 -DWITH_SSL=yes

make && make install

ln -s /usr/local/mysql/include/* /usr/local/include/

ln -s /usr/local/mysql/lib/libmysqlclient.so.16 /usr/lib64/

chmod +w /usr/local/mysql

chown -R mysql:mysql /usr/local/mysql

①、创建MySQL数据库存放目录

mkdir -p /data/mysql/data

mkdir -p /data/mysql/binlog/binlog

chmod +w /data/mysql

chown -R mysql:mysql /data/mysql

②、以mysql用户帐号的身份建立数据表：

/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/data/mysql/data --user=mysql

③、创建my.cnf配置文件：

cp support-files/my-medium.cnf /data/mysql/my.cnf

在/data/mysql/my.cnf添加以下参数

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/##

basedir = /usr/local/mysql

datadir = /data/mysql/data

log-error = /data/mysql/mysql_error.log

pid-file = /data/mysql/mysql.pid

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/##

④、创建管理MySQL数据库的shell脚本：

vi /data/mysql/mysql

输入以下内容（这里的用户名root和密码12345678接下来的步骤会创建）：

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

#!/bin/sh   

mysql_port=3306   

mysql_username="root"  

mysql_password="123456"  

function_start_mysql()   

{   

    printf "Starting MySQL...\n"  

    /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysql/my.cnf 2>&1 > --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/data &

}   

function_stop_mysql()   

{   

    printf "Stoping MySQL...\n"  

    /usr/local/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: /data/mysql/mysql {start|stop|restart|kill}\n"  

fi  

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

⑤、赋予shell脚本可执行权限：

chown -R mysql:mysql /data/mysql

chmod +x /etc/rc.d/rc.local

chmod +x /data/mysql/mysql

⑥、启动MySQL：

/data/mysql/mysql start

设定开机启动mysql

vi /etc/rc.d/rc.local

输入

/data/mysql/mysql start

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/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

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 'root'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY '123456';

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

⑨、（可选）停止MySQL：

/data/mysql/mysql stop

四、编译安装PHP（FastCGI模式）

1、建立 www 用户

/usr/sbin/groupadd www

/usr/sbin/useradd -g www -s /sbin/nologin www

2、解压安装

tar zxvf php-7.0.12.tar.gz

cd php-7.0.12

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --enable-opcache=yes   --with-freetype-dir=/usr/local/freetype --enable-fpm --with-mcrypt --enable-mbstring --with-curl --disable-debug  --disable-rpath --enable-inline-optimization --with-bz2  --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --with-mhash --with-pcre-regex --with-pdo-mysql  --enable-mysqlnd --with-mysqli --with-gd --with-jpeg-dir --with-iconv-dir --with-png-dir --with-libxml-dir --enable-xml  --enable-zip --enable-calendar  --enable-wddx --enable-bcmath --enable-shmop --enable-gd-native-ttf --with-openssl --with-xmlrpc --enable-soap --enable-maintainer-zts --enable-exif  --enable-ftp

make ZEND_EXTRA_LIBS='-liconv'

make install

3、拷贝php.ini等配置文件

cp php.ini-production /usr/local/php/etc/php.ini

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

cd ../

4、编译安装PHP5扩展模块

yum install git  ImageMagick ImageMagick-devel

cd /data/soft

tar zxf libmemcached-1.0.18.tar.gz

cd libmemcached-1.0.18

./configure --prefix=/usr/local/libmemcached --with-memcached

make && make install

cd ../

如果没有去百度云盘下载压缩包，可用github命令下载

git clone https://github.com/php-memcached-dev/php-memcached.git

tar zxvf php-memcached.tar.gz

cd php-memcached

git checkout php7

/usr/local/php/bin/phpize

./configure --enable-memcached --with-php-config=/usr/local/php/bin/php-config  --with-libmemcached-dir=/usr/local/libmemcached  --disable-memcached-sasl

make

make install

cd ../

如果没有去百度云盘下载压缩包，可用github命令下载

git clone https://github.com/phpredis/phpredis.git

tar zxvf phpredis.tar.gz

cd phpredis

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make

make install

cd ../

tar zxvf imagick-3.4.3RC1.tgz

cd imagick-3.4.3RC1/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make

make install

cd ../

5、修改php.ini文件

vi /usr/local/php/etc/php.ini

修改 php.ini ，去掉 date.timezone 的注释，并设置为 date.timezone = PRC

手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"

修改为

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20151012/"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

并在此行后增加以下几行，然后保存：

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

extension = "memcached.so"

extension = "imagick.so"

extension = "redis.so"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

再查找zlib.output_compression = Off

修改为zlib.output_compression = On

按住shift+g跳到php.ini最后一行，加上opcache相关配置

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

zend_extension="/usr/local/php/lib/php/extensions/no-debug-zts-20151012/opcache.so"

opcache.force_restart_timeout=3600

opcache.memory_consumption=1024

opcache.optimization_level=1

opcache.interned_strings_buffer=8

opcache.max_accelerated_files=4096

opcache.revalidate_freq=60

opcache.fast_shutdown=1

opcache.enable=1

opcache.enable_cli=1

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

添加php比较危险的函数

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

disable_functions = exec,system,passthru,ini_alter,dl,openlog,syslog,readlink,symlink,link,leak,proc_open,popepassthru,chroot,scandir,chgrp,chown,escapeshellcmd,escapeshellarg,proc_get_status,popen,com,eval,gzuncompress,php_admin_value,php_admin_flag

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

6、创建php的启动角本　

vi /usr/local/php/php-fpm

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#!/bin/sh   

function_start_php()   

{   

    printf "Starting Php-fpm...\n"  

    /usr/local/php/sbin/php-fpm -g /usr/local/php/var/run/php-fpm.pid

}   

function_stop_php()   

{   

    printf "Stoping Php-fpm...\n"  

    kill -INT `cat /usr/local/php/var/run/php-fpm.pid`

}   

function_restart_php()   

{   

    printf "Restarting Php-fpm...\n"         

    kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`    

}  

if [ "$1" = "start" ]; then   

    function_start_php   

elif [ "$1" = "stop" ]; then   

    function_stop_php   

elif [ "$1" = "restart" ]; then   

function_restart_php  

else  

    printf "Usage: /usr/local/php/php-fpm {start|stop|restart}\n"  

fi  

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

给php-fpm执行以下命令

chmod +x /usr/local/php/php-fpm

启动PHP命令

/usr/local/php/php-fpm start

启动php-cgi进程，监听127.0.0.1的9000端口，p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ww

五、安装Nginx(Tengine)

1、安装Nginx所需的库,解压这些文件，并不需要安装：

tar -xvf zlib-1.2.8.tar.gz

tar zxvf pcre-8.37.tar.gz

2、安装Tengine

tar zxvf tengine-2.1.0.tar.gz

cd tengine-2.1.0/

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/data/soft/pcre-8.37 --with-zlib=/data/soft/zlib-1.2.8

注意：--with-pcre=/data/soft/pcre-8.37指向的是源码包解压的路径，而不是安装的路径，否则会报错,同样,openssl zlib的路径都是源码包解压路径s。

make && make install 

cd ../

3、创建Nginx日志目录

mkdir -p /data/logs

chmod +w /data/logs

chown -R www:www /data/logs

4、创建Nginx配置文件

①、在/usr/local/nginx/conf/目录中创建nginx.conf文件：

>/usr/local/nginx/conf/nginx.conf

vi /usr/local/nginx/conf/nginx.conf

输入以下内容：

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

5、启动Nginx

ulimit -SHn 65535

/usr/local/nginx/sbin/nginx

六、在不停止Nginx服务的情况下平滑变更Nginx配置

1、修改/usr/local/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/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/nginx/conf/nginx.conf syntax is ok

the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully

2、平滑重启：

①、对于Nginx 0.8.以后的版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：

/usr/local/nginx/sbin/nginx -s reload

3、创建Nginx启动脚本

vi /usr/local/nginx/nginx

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#!/bin/sh

nginx_s="/usr/local/nginx/sbin/nginx"

function_start_nginx()   

{   

    printf "Starting nginx...\n"

    ${nginx_s} 

}   

function_stop_nginx()   

{   

    printf "Stoping nginx...\n"  

    ${nginx_s} -s stop

}   

function_restart_nginx()   

{   

    printf "Restarting nginx...\n" 

    ${nginx_s} -s reload

}  

if [ "$1" = "start" ]; then   

    function_start_nginx   

elif [ "$1" = "stop" ]; then   

    function_stop_nginx   

elif [ "$1" = "restart" ]; then 

    function_restart_nginx  

else  

    printf "Usage: /usr/local/nginx/nginx {start|stop|restart}\n"  

fi

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

chmod +x /usr/local/nginx/nginx

七、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

/data/mysql/mysql start

/usr/local/php/php-fpm start

/usr/local/nginx/sbin/nginx

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~/

八、优化Linux内核参数

vi /etc/sysctl.conf

在末尾增加以下内容：

/~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# 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

九、编写每天定时切割Nginx日志的脚本

1、创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh

vi /usr/local/nginx/sbin/cut_nginx_log.sh

输入以下内容：

#!/bin/bash

# This script run at 00:00

# The Nginx logs path

logs_path="/data/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/nginx/nginx.pid`

chmod +x /usr/local/nginx/sbin/cut_nginx_log.sh

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/nginx/sbin/cut_nginx_log.sh
