主服务器IP:192.168.1.104

先配置主服务器的rsyslog:

# vim /etc/rsyslog.conf

$ModLoad imuxsock
$SystemLogRateLimitInterval 0	# 关闭速率限制,否则量大的话会有日志被丢弃
$ModLoad imklog
$ModLoad immark
$ModLoad imudp				# 开启UDP,nginx会使用
$UDPServerRun 514
$ModLoad imtcp				# 开启TCP,从服务器使用
$InputTCPServerRun 514
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf

:msg,contains,"Core power limit notification"		~	# 丢弃CPU省电模式通知
:msg,contains,"Core power limit normal"			~
:msg,contains,"Package power limit notification"	~
:msg,contains,"Package power limit normal"		~
*.info;mail.none;authpriv.none;cron.none;local0.none	/var/log/messages

:msg,contains,"Accepted publickey for www-data from 192.168.1.104 port"			~	# 丢弃主服务器同步代码时的用户登陆信息
:msg,contains,"pam_unix(sshd:session): session opened for user www-data by (uid=0)"	~
:msg,contains,"Received disconnect from 192.168.1.104: 11: disconnected by user"	~
:msg,contains,"pam_unix(sshd:session): session closed for user www-data"		~
authpriv.*,		/var/log/secure
mail.*			/var/log/maillog
cron.*			/var/log/cron
*.emerg			*
uucp,news.crit		/var/log/spooler
local7.*		/var/log/boot.log

if $syslogfacility-text == 'local0' and $syslogtag startswith 'php-fpm' then	/var/log/httpd/php-fpm_error.log
if $syslogfacility-text == 'local0' and $syslogtag == 'nginx_access:' then	/var/log/httpd/nginx_access.log
if $syslogfacility-text == 'local0' and $syslogtag == 'nginx_error:' then	/var/log/httpd/nginx_error.log
if $syslogfacility-text == 'local0' and $syslogtag == 'http-error:' then	/var/log/httpd/error.log
if $syslogfacility-text == 'local0' and $syslogtag == 'http-access:' then	/var/log/httpd/access.log
if $syslogfacility-text == 'local0' and $syslogtag startswith 'redis' then	/var/log/httpd/redis.log
#local0.*		/var/log/local0.log

if $syslogfacility-text == 'user' and $syslogtag == 'php:' then			/var/log/httpd/php_error.log
if $syslogfacility-text == 'user' and $syslogtag == 'php:' then			~
if $syslogfacility-text == 'user' and $syslogtag startswith 'laravel' then	/var/log/httpd/laravel.log
if $syslogfacility-text == 'user' and $syslogtag startswith 'laravel' then	~
user.*			/var/log/httpd/user.log

配置从服务器的rsyslog:

$ModLoad imuxsock
$SystemLogRateLimitInterval 0
$ModLoad imklog
$ModLoad immark
$ModLoad imtcp
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf

$WorkDirectory /var/lib/rsyslog	# where to place spool files
$ActionQueueFileName fwdRule1	# unique name prefix for spool files
$ActionQueueMaxDiskSpace 1g	# 1gb space limit (use as much as possible)
$ActionQueueSaveOnShutdown on	# save messages to disk on shutdown
$ActionQueueType LinkedList	# run asynchronously
$ActionResumeRetryCount -1	# infinite retries if host is down
*.* @@192.168.1.104:514		# 发送到主服务器

配置主服务器的日志轮循,改为每天切换,保留6天的日志:

# vim /etc/logrotate.d/httpd
/var/log/httpd/*log {
	daily
	rotate 6
	missingok
	notifempty
	sharedscripts
	delaycompress
	postrotate
	/sbin/service httpd reload > /dev/null 2>/dev/null || true
	endscript
}

# vim /etc/logrotate.d/syslog
/var/log/cron
/var/log/maillog
/var/log/messages
/var/log/secure
/var/log/spooler {
	daily
	rotate 6
	sharedscripts
	postrotate
	/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
	endscript
}

修改原来的apache配置,把日志发到syslog,这里为了指定tag,使用管道发到loggerphp的error_log = syslog,会发送到user这个facility上

# vim /etc/httpd/conf/httpd.conf
ErrorLog "|logger -t http-error -p local0.err"
CustomLog "|logger -t http-access -p local0.info" combined

从服务器上编译安装php7

# yum install cc gcc gcc+ gcc-c++ libxml2 libxml2-devel openssl-devel curl curl-devel
# ./configure --prefix=/usr/local/php7 \
 --with-libdir=lib64 \
 --with-freetype-dir \
 --with-libxml-dir \
 --with-png-dir \
 --with-curl \
 --with-gd \
 --with-gettext \
 --with-kerberos \
 --with-mysqli \
 --with-openssl \
 --with-pcre-regex \
 --with-pdo-mysql \
 --with-pdo-sqlite \
 --with-pear \
 --with-xmlrpc \
 --with-zlib \
 --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data\
 --enable-bcmath \
 --enable-libxml \
 --enable-inline-optimization \
 --enable-gd-native-ttf \
 --enable-mbregex \
 --enable-mbstring \
 --enable-pcntl \
 --enable-shmop \
 --enable-soap \
 --enable-sockets \
 --enable-sysvsem \
 --enable-xml \
 --enable-zip
# make
# make install

# cp php.ini-development /usr/local/php7/lib/php.ini
# cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
# cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
# chkconfig --add php-fpm

编译安装libmcrypt

编译安装php-mcrypt

# /usr/local/php7/bin/phpize
# ./configure --with-php-config=/usr/local/php7/bin/php-config
# make
# make install

同上操作,编译安装php-redis

修改配置/usr/local/php7/lib/php.ini

error_log = syslog
extension_dir=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/
extension=mcrypt.so
extension=redis.so

修改配置/usr/local/php7/etc/php-fpm.conf

error_log = syslog
syslog.facility = local0
syslog.ident = php-fpm

按自己的需求配置好/usr/local/php7/etc/php-fpm.d/www.conf后,即可启动php-fpm

编译安装pcre,为安装nginx做准备

# ./configure
# make
# make install

# ln -s /lib64/libpcre.so.0.0.1 /lib64/libpcre.so.1

编译安装nginx

# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
# make
# make install

配置nginx

# vim /usr/local/nginx/conf/nginx.conf
user  www-data;
worker_processes  2;
worker_rlimit_nofile 65535;

error_log  syslog:server=192.168.1.104,facility=local0,tag=nginx_error;
# 注意:这里是用udp端口,默认514,所以主服务器rsyslog要开udp支持
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
    use epoll;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log syslog:server=192.168.1.104,facility=local0,tag=nginx_access main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    gzip  on;

    server {
        listen       81;	#80已经被apache用了
        #server_name  localhost;
        root /var/www/laravel/public;
        index index.php index.html index.htm;

        location / {
            try_files $uri $uri/ /index.php?$query_string;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ \.php$ {
            try_files $uri /index.php =404;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
    }
}

esac

exit $RETVAL

添加到启动服务中

# chkconfig --add nginx

之前使用memcached,一个月左右memcached就会挂掉,不知道是不是版本问题,这次就使用redis来做缓存,先安装redis默认使用的jemalloc

# ./autogen.sh
# ./configure -prefix=/usr/local/jemalloc

安装redis,如果在安装jemalloc前make了redis报错找不到jemalloc.h,就删掉目录重新解压再make

# make
# make install PREFIX=/usr/local/redis
# cp redis.conf /usr/local/redis/
# vim /usr/local/redis/redis.conf
daemonize yes		# 改为yes,在后台运行
#bind 127.0.0.1		# 注释掉这里,否则只能本机访问
protected-mode no	# 改为no,否则只能本机访问
syslog-enabled yes	# 使用syslog记录日志
syslog-ident redis
syslog-facility local0

# cp utils/redis_init_script /etc/init.d/redis
# vim /etc/init.d/redis
// 添加chkconfig支持
# chkconfig: 2345 63 35
# description: Redis
// 修改默认路径
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
CONF="/usr/local/redis/redis.conf"

# chkconfig --add redis // 添加到服务中

到这安装配置就都完成了,几个要注意的坑:
1.nginx的syslog用的是UDP端口,默认为514
2.redis默认使用jemalloc分配内存,需要先安装
3.redis配置中bind 127.0.0.1要注释,protected-mode要设为no,否则只能本机访问,或者需要设置密码
4.有些软件发syslog时,tag会加上[pid],则判断时使用startswith比较稳妥
5.rsyslog的规则是只要匹配就都会记录,并不是匹配到之后后面的规则就无效了
6.安装php扩展时,大多需要先安装一些库,并且需要库的头文件,所以yum安装时把库-devel也一起装上
