CentOS6.8搭建LNMP环境

selinux可能会致使编译安装失败，我们先禁用它。永久禁用，需要重启生效

sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g’ /etc/selinux/config

临时禁用，不需要重启

setenforce 0
iptables -I INPUT -p tcp –dport 80 -j ACCEPT

安装必备工具

yum -y install gcc automake autoconf libtool make gcc-c++ glibc libxslt-devel 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-devel libidn libidn-devel openssl openssl-devel pcre pcre-devel libmcrypt libmcrypt-devel cmake

几点说明：

pcre、openssl、zlib是安装nginx时需要的
cmake是安装MySQL时需要的

配置下载地址

cat > /usr/local/src/url << “EOF”
http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
http://nginx.org/download/nginx-1.8.1.tar.gz
http://jp2.php.net/distributions/php-5.6.30.tar.gz
http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.30.tar.gz
EOF

下载

wget -P /usr/local/src -i /usr/local/src/url

解压

cd /usr/local/src
for i in *.tar.gz ; do tar zxvf $i; done

安装cmake

cd cmake-2.8.10.2
./bootstrap
gmake && gmake install

安装mysql

创建mysql安装目录、组、账号

groupadd mysql ; useradd -g mysql -s /sbin/nologin mysql
mkdir -p /data/mysql ; chown -R mysql:mysql /data/mysql
mkdir -p /usr/local/mysql ; chown -R mysql:mysql /usr/local/mysql

开始安装

cd ../mysql-5.6.30
cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/data/mysql \
-DMYSQL_TCP_PORT=3306 \
-DENABLE_DOWNLOADS=1 .
make && make install

初始化数据库 拷贝配置文件

cd /usr/local/mysql/
scripts/mysql_install_db –user=mysql –datadir=/data/mysql
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld

添加启动目录

vim /etc/profile

按G移动光标到最后一行o插入以下两行

PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH

更新配置文件

source /etc/profile

设置开机启动并启动

chkconfig mysqld on
service mysqld start

登陆测试，默认是没有密码,直接回车就可进入

mysql -uroot -p

设置mysql密码

SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘password’);

查看用户

select user,host from mysql.user;

删除不必要的用户

drop user “”@localhost;
drop user “”@c65mini.localdomain;
drop user root@c65mini.localdomain;
drop user root@’::1′;

赋予账号远程访问的权限

GRANT ALL PRIVILEGES ON *.* TO ‘root’@’127.0.0.1’ IDENTIFIED BY ‘你的密码’ WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO ‘root’@’localhost’ IDENTIFIED BY ‘你的密码’ WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO ‘root’@’c65mini.localdomain’ IDENTIFIED BY ‘你的密码’ WITH GRANT OPTION;

针对数据库创建一个全部权限的用户

grant all on wordpress.* to ‘admin’@’localhost’ identified by ‘123456’;
UPDATE user SET password=PASSWORD(‘123456′) WHERE user=’root’;

其它一些信息查询： 检查mysql版本

mysql -uroot -p”密码” -e “select version();”

安装php

cd /usr/local/src/php-5.6.30
./configure \
–prefix=/usr/local/php \
–with-config-file-path=/usr/local/php/etc \
–enable-fpm \
–with-fpm-user=php-fpm \
–with-fpm-group=php-fpm \
–with-mysql=/usr/local/mysql \
–with-mysql-sock=/usr/local/mysql/mysql.sock \
–with-libxml-dir \
–with-gd \
–with-jpeg-dir \
–with-png-dir \
–with-freetype-dir \
–with-iconv-dir \
–with-zlib-dir \
–with-mcrypt \
–enable-soap \
–enable-gd-native-ttf \
–enable-ftp \
–enable-mbstring \
–enable-exif \
–enable-zend-multibyte \
–disable-ipv6 \
–with-pear \
–with-curl \
–with-openssl \
–disable-fileinfo
make && make install

创建用户

groupadd www ; useradd -g www /sbin/nologin www

修改配置文件

cp php.ini-production /usr/local/php/etc/php.ini
cat > /usr/local/php/etc/php-fpm.conf << “EOF”
[global]
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
user = www
group = www
listen.owner = www
listen.group = www
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
EOF

保存配置文件后，检验配置是否正确的方法, 如果出现诸如 “test is successful” 字样，说明配置没有问题。

/usr/local/php/sbin/php-fpm -t

启动php-fpm

cp /usr/local/src/php-5.6.30/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.d/php-fpm
service php-fpm start
chkconfig php-fpm on

检测是否启动:

ps aux |grep php-fpm

看看是不是有很多个进程（大概20多个）。

安装nginx

cd ../nginx-1.8.1
./configure \
–prefix=/usr/local/nginx \
–user=www \
–group=www \
–with-http_realip_module \
–with-http_sub_module \
–with-http_gzip_static_module \
–with-pcre

编译nginx

make && make install

因为nginx比较小，所以很快就会安装完，而且也不会出什么错误

编写nginx启动脚本，并加入系统服务

cat > /etc/init.d/nginx <<“EOF”
#!/bin/bash
# chkconfig: – 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN=”/usr/local/nginx/sbin/nginx”
NGINX_CONF=”/usr/local/nginx/conf/nginx.conf”
NGINX_PID=”/usr/local/nginx/logs/nginx.pid”
RETVAL=0
prog=”Nginx”
start() {
echo -n $”Starting $prog: “
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop() {
echo -n $”Stopping $prog: “
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload(){
echo -n $”Reloading $prog: “
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart(){
stop
start
}
configtest(){
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case “$1” in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $”Usage: $0 {start|stop|reload|restart|configtest}”
RETVAL=1
esac
exit $RETVAL
EOF

保存后，更改权限:

chmod 755 /etc/init.d/nginx
chkconfig –add nginx
chkconfig nginx on

更改nginx配置

首先把原来的配置文件清空: 写入如下内容:

cat > /usr/local/nginx/conf/nginx.conf << “EOF”

include vhosts/*.conf;
}
EOF

mkdir -p /usr/local/nginx/conf/vhosts

cat > /usr/local/nginx/conf/vhosts/default.conf << “EOF”

server
{
listen 80 default_server;
server_name localhost;
index index.html index.htm index.php;
root /tmp/403;
deny all;
}
EOF

mkdir -p /data/www/test

cat > /usr/local/nginx/conf/vhosts/test.conf << “EOF”

server
{
listen 80;
server_name test.com;
index index.html index.htm index.php;
root /data/www/test;
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass unix:/tmp/php-fcgi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/www/test$fastcgi_script_name;
}
}
EOF

保存配置后，先检验一下配置文件是否有错误存在:

/usr/local/nginx/sbin/nginx -t

启动看是否有进程。

service nginx start
ps aux |grep nginx

测试是否解析php文件

cat > /data/www/test/2.php << “EOF”
<?php
echo “测试php是否解析”;
?>
EOF

测试php是否解析

curl -x127.0.0.1:80 test.com/2.php
