更换yum源为阿里源

#!/bin/bash

#备份本地yum源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

#获取阿里的yum源配置
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

#更新cache
yum makecache

#更新
yum -y update

扩容交换空间

由于我的是学生服务器，穷啊，还没毕业，真是的！哼！所以需要扩容交换空间。有钱的老板可以跳过这一步。

#!/bin/bash

#服务器上的交换分区建议创建物理内存的一般即可
dd if=/dev/zero of=/swapfile bs=1k count=1024000
mkswap /swapfile
swapon /swapfile

#在文件系统设置
echo "/swapfile  swap  swap    defaults 0 0" >> /etc/fstab

sysctl vm.swappiness=100

这个问题出现在编译安装mysql的时候，由于编译安装需要大量内存，直接把我的小服务器给中断了，只好这么做了。编译安装时出现的错误提示是internal compiler error: Killed (program cc1plus)意思就是内存不足了，给你中断了。

编译安装PHP（7.3.0）

  1. 安装依赖（安装了nginx+php的依赖，满足大部分场景，需要扩展请自行添加依赖） 
    yum install wget vim pcre pcre-devel openssl openssl-devel libicu-devel 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 ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel openssl openssl-devel -y

  2. 创建用户和用户组

    groupadd www
useradd -g www www

  3. 添加搜索路径到配置文件

    cd /opt

echo '/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64'>>/etc/ld.so.conf

    更新配置文件

    ldconfig -v

    创建编译ldap组件时需要的配置文件

    cp -frp /usr/lib64/libldap* /usr/lib/

  4. 下载PHP

    #-c 为断点续链命令
wget -c https://www.php.net/distributions/php-7.3.4.tar.gz

#解压
tar -zxvf php-7.3.4.tar.gz

#切入目录
cd php-7.3.4

  5. ./configure校验文件和依赖

    #更新ld缓存文件

ldconfig -v 

#校验

#.configure检查
./configure --prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \
--enable-mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--enable-mysqlnd-compression-support \
--with-iconv-dir \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir \
--enable-xml \
--disable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--enable-mbregex \
--enable-mbstring \
--enable-intl \
--enable-ftp \
--with-gd \
--enable-gd-jis-conv \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--with-gettext \
--disable-fileinfo \
--enable-opcache \
--with-pear \
--enable-maintainer-zts \
--with-ldap=shared \
--without-gdbm \
--enable-static \
--with-kerberos \
--with-libdir=lib64 \
--with-pcre-regex \
--with-pdo-sqlite \
--with-xsl

  6. 可能出现的问题

    1. libzip >=0.11 提示 意思是版本过低 需要下高版本的依赖http://www.kwx.gd/PHPEnvironment/CetnOS-libzip.html

    2. configure: error: libxml2 not found. Please check your libxml2 installation.  

      yum install -y libxml2-devel

    3. configure: error: Please reinstall the BZip2 distribution

      yum install -y bzip2-devel

    4. configure: error: cURL version 7.15.5 or later is required to compile php with cURL support

      yum install -y curl-devel

    5. configure: error: jpeglib.h not found.

      yum install -y libjpeg-devel

    6. checking for libzip... configure: error: system libzip must be upgraded to version >= 0.11

      #先删除旧版本
yum remove -y libzip

#下载编译安装
wget https://nih.at/libzip/libzip-1.2.0.tar.gz
tar -zxvf libzip-1.2.0.tar.gz
cd libzip-1.2.0
./configure
make && make install

  7. 编译安装

    make && make install

    可能会出现的问题 usr/local/include/zip.h:59:21: fatal error: zipconf.h: No such file or directory

    cp /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h

  8. 配置php.ini文件

    #迁移文件至php安装目录下
cp php.ini-development /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

#配置php.ini文件

expose_php = Off
short_open_tag = ON
max_execution_time = 300
max_input_time = 300
memory_limit = 128M
post_max_size = 32M
date.timezone = Asia/Shanghai
mbstring.func_overload=2
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-zts-20170718/"
extension = "ldap.so"

  9. OPcache 缓存参数：

    [opcache]
zend_extension="opcache.so"
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.max_wasted_percentage=5
opcache.use_cwd=0
opcache.validate_timestamps=1
opcache.revalidate_freq=60
opcache.revalidate_path=0
opcache.enable_file_override=0
opcache.fast_shutdown=1
#opcache.optimization_level=0xffffffff
opcache.max_file_size=0
#opcache.consistency_checks=0
#opcache.force_restart_timeout=180
opcache.error_log=/usr/local/php/var/log/opcache.log
opcache.log_verbosity_level=1

  10. php安全禁用函数:

    disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server,escapeshellcmd,dll,popen,disk_free_space,checkdnsrr,checkdnsrr,getservbyname,getservbyport,disk_total_space,posix_ctermid,posix_get_last_error,posix_getcwd, posix_getegid,posix_geteuid,posix_getgid, posix_getgrgid,posix_getgrnam,posix_getgroups,posix_getlogin,posix_getpgid,posix_getpgrp,posix_getpid, posix_getppid,posix_getpwnam,posix_getpwuid, posix_getrlimit, posix_getsid,posix_getuid,posix_isatty, posix_kill,posix_mkfifo,posix_setegid,posix_seteuid,posix_setgid, posix_setpgid,posix_setsid,posix_setuid,posix_strerror,posix_times,posix_ttyname,posix_uname

  11. 配置www.conf

    [www]
user = www
group = www
listen = /usr/local/php/var/run/php-cgi.sock
listen.backlog = -1
listen.owner = www
listen.group = www
listen.mode = 0660
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 300
pm.start_servers = 150
pm.min_spare_servers = 150
pm.max_spare_servers = 300
slowlog = /usr/local/php/var/log/slow.log
request_slowlog_timeout = 60
request_terminate_timeout = 180

  12. 配置php-fpm.conf

    pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = error
include=/usr/local/php/etc/php-fpm.d/*.conf

  13. 创建php-fpm服务启动脚本：

    vim /usr/lib/systemd/system/php-fpm.service

[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target

[Service]
Type=simple
PIDFile=/usr/local/php/var/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

  14. 启动php-fpm服务并、开机自启动：

    systemctl start php-fpm.service
systemctl enable php-fpm.service

编译安装Nginx

  1. 安装依赖

    yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

  2. 下载nginx

    wget -c http://nginx.org/download/nginx-1.14.2.tar.gz

    http://nginx.org/en/download.html

  3. ./configure检查文件及依赖

        server_name  localhost;


        access_log  logs/host.access.log  main;

        location / {
            alias   /data/wwwroot;   #html文件目录
            index  index.html index.htm index.php;
        }

        error_page  404              /404.html;

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

        location ~* \.php$ {
            alias   /data/wwwroot;   #html文件目录

            fastcgi_param  SCRIPT_FILENAME  /data/www$fastcgi_script_name;
            include         fastcgi_params;
        }

    }
}

  6. 开启nginx

    #测试配置文件是否正确
/usr/local/nginx/sbin/nginx -t

#启动nginx
/usr/local/nginx/sbin/nginx

#将nginx加入开机启动项
echo "/usr/local/nginx/sbin/nginx" >> /etc/rc.d/rc.local 
chmod +x /etc/rc.d/rc.local

  7. 将nginx添加到service服务

    #!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig: - 85 15
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
# proxy and IMAP/POP3 proxy server
