CentOS7最大改变是systemd代替过去的systemV服务,于是配置服务的方式改变了,用systemctl替代过去的service, chkconfig等命令。
网站搬迁服务器,全新服务器当然用新系统,于是安装上CentOS7。

重启服务器一次
编译配置完毕。启用和启动服务
sudo systemctl daemon-reload
sudo systemctl enable nginx php-fpm
sudo systemctl start nginx php-fpm
---------------------------------------------------------------------
PHP5.4有点老了,准备装个最新稳定版5.6试试并且为即将到来的PHP7做准备。以前是在单独的一台服务器上跑测试,现在一台服务器上该如何设置呢?
先编译PHP5.6,注意前缀变成了 /opt
./configure --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu \
--with-layout=GNU \
--prefix=/opt/local --exec-prefix=/opt/local \
--sysconfdir=/etc --libdir=/opt/local/lib/php \
--sbindir=/opt/local/sbin --sharedstatedir=/usr/com --datadir=/opt/local/share \
--includedir=/opt/local/include --libexecdir=/opt/local/libexec \
--localstatedir=/run --mandir=/opt/local/share/man --infodir=/opt/local/share/info \

--with-pic --with-curl --with-freetype-dir --with-png-dir \

--enable-zip --with-bz2 \
--without-unixODBC --enable-mbregex \
--enable-fpm --with-fpm-user=www --with-fpm-group=www --with-fpm-systemd \
--disable-tokenizer --disable-phar \
--enable-sysvsem --enable-sysvshm --enable-sysvmsg \
--disable-cgi \
\
--with-pgsql=/usr/pgsql-9.4 --with-pdo-pgsql=/usr/pgsql-9.4 \
\
--with-pdo-mysql --with-mysql --with-mysql-sock=/var/lib/mysql/mysql.sock --enable-mysqlnd \
\
然后编辑 /etc/php-fpm2.conf,注意php-fpm2.pid
pid = /run/php-fpm/php-fpm2.pid
; ....... 删除[www0] [www1]小结, 其他不变
[www2]
prefix = /run/php-fpm/pools/$pool
listen = /run/php-fpm/php-fpm2.sock
listen.backlog = 2048
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = static
pm.max_children = 20
pm.max_requests = 500
pm.status_path = /status
request_terminate_timeout = 600
request_slowlog_timeout = 30
slowlog = /var/log/nginx/slow.log
env[TMP] = /run/php-fpm/tmp
env[TMPDIR] = /run/php-fpm/tmp
env[TEMP] = /run/php-fpm/tmp
[www3]
prefix = /run/php-fpm/pools/$pool
listen = /run/php-fpm/php-fpm3.sock
listen.backlog = 2048
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = static
pm.max_children = 20
pm.max_requests = 500
pm.status_path = /status
request_terminate_timeout = 600
request_slowlog_timeout = 30
slowlog = /var/log/nginx/slow.log
env[TMP] = /run/php-fpm/tmp
env[TMPDIR] = /run/php-fpm/tmp
env[TEMP] = /run/php-fpm/tmp
然后复制php.ini
sudo cp -p /etc/php.ini /opt/php56.ini
php5.6的配置相对5.4没啥变化,除了 default_charset = "UTF-8" 这个需要设置
=======================
关键来了,如何配置php-fpm服务呢?
编辑 /etc/systemd/system/php-fpm2.service
[Unit]
Description=The PHP FastCGI Process Manager @develop
After=syslog.target network.target
Before=nginx.service
[Service]
#Type=forking
Type=notify
PIDFile=/run/php-fpm/php-fpm2.pid
ExecStart=/opt/local/sbin/php-fpm -c /opt/php56.ini --fpm-config /etc/php-fpm2.conf
ExecReload=/bin/kill -USR2 $MAINPID
PrivateTmp=true
WatchdogSec=30
Restart=always
[Install]
WantedBy=multi-user.target
注意上面PIDFile, ExecStart的参数变化了。另外Type用原来的forking也行,不过改成notify有个好处下面说。
修改 /etc/nginx/nginx.conf文件
http {
upstream php_servers{
server unix:/run/php-fpm/php-fpm0.sock;
server unix:/run/php-fpm/php-fpm1.sock;
#server unix:/run/php-fpm/php-fpm2.sock ;
#server unix:/run/php-fpm/php-fpm3.sock ;
}
upstream php_servers2{
#server unix:/run/php-fpm/php-fpm0.sock;
#server unix:/run/php-fpm/php-fpm1.sock;
server unix:/run/php-fpm/php-fpm2.sock ;
server unix:/run/php-fpm/php-fpm3.sock ;
}
然后修改nginx站点配置,在测试网站指定使用php_servers2作为解析
location ~ \.php$ {
try_files $uri =404; # 屏蔽日志中 Primary script unknown
access_log off;
log_not_found off;
#fastcgi_pass php_servers;
fastcgi_pass php_servers2;
include fastcgi.conf;
}
重启服务
sudo systemctl daemon-reload
sudo systemctl start php-fpm2
sudo systemctl reload nginx
这样多版本PHP就同时跑起来了。
看看php-fpm2.service 的状态呢
$ sudo systemctl status php-fpm2
php-fpm2.service - The PHP FastCGI Process Manager -develop
Loaded: loaded (/etc/systemd/system/php-fpm2.service; enabled)
Active: active (running) since Thu 2015-09-24 16:19:08 CST; 1 day 4h ago

Status: "Processes active: 1, idle: 39, Requests: 197553, slow: 0, Traffic: 17.2req/sec"

├─ 2845 php-fpm: pool www3
├─ 2846 php-fpm: pool www2
├─ 2847 php-fpm: pool www3
看到这一行没?
Status: "Processes active: 1, idle: 39, Requests: 197553, slow: 0, Traffic: 17.2req/sec"
这就是notify类型的特色,可以提供实时统计数据。
