    #修改nginx用户组
    user  nginx;
    
    #设置工作进程数 方便的话可以直接设置成auto    
    worker_processes auto;
    
    #lscpu 可以查看下cpu的数量 
    #worker_processes一般设置和CPU数量一样且配合worker_cpu_affinity一起配置
    worker_processes 2;
    worker_cpu_affinity 01 10;
    
    #配置nginx错误日志
    error_log /var/log/nginx/error.log;

    #nginx的启动与重启
    /usr/local/nginx/sbin/nginx -s quit     #nginx停止
    /usr/local/nginx/sbin/nginx -s reload     #nginx reload
    /usr/local/nginx/sbin/nginx                #nginx启动
    
    #nginx设置开机自启动
    #即在rc.local增加启动代码就可以了
    vi /etc/rc.local
    #增加一行 /usr/local/nginx/sbin/nginx
    
    #设置执行权限
    chmod 755 /etc/rc.local

3、redis安装

    #安装mysql server
    yum install mysql-community-server
    
    #启动mysqld
    systemctl start mysqld.service
    systemctl status mysqld.service
    systemctl enable mysqld.service
    
    #查看临时密码 grep 'A temporary password' /var/log/mysqld.log
    #登录设置root新密码 alter user 'root'@'localhost' identified by 'xxxx';
　　 #修改密码策略 ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
　　# set global validate_password_policy=LOW;

5、php_screw-1.5 扩展编译
    #进入http://sourceforge.net/projects/php-screw/下载最新版本php_screw-1.5.tar.gz
    #cd /home/tools
    tar -zxvf php_screw-1.5.tar.gz
    cd php_screw-1.5
    
    #更改加密策略
    vim php_screw.h
    #修改 define PM9SCREW “	PHPSCREW	”
    
    vim my_screw.h
    #数组中数据随便修改,但最多保持在5位数
    
    vim php_screw.c
    #CG(extended_info) = 1; 修改为 CG(compiler_options) |= ZEND_COMPILE_EXTENDED_INFO;
    
    /usr/bin/phpize
    ./configure --with-php-config=/usr/bin/php-config
    make && make install
    #编译会在/home/tools/php_screw-1.5/modules文件夹
    #/usr/lib64/php/modules/文件夹生成php_screw.so文件
    
    #php.ini添加extension=php_screw.so
    vim /etc/php.ini 
    systemctl restart php-fpm.service
    
    #生成加密二进制文件screw
    cd /home/tools/php_screw-1.5/tools
    make
    #make生成二进制文件screw
    
    cp screw /usr/bin/screw
    #接下来就玩起来吧

6、openssh升级到7.9
    
    #先安装telnet服务,以防卸载openssh后连接不到服务器
    yum list telnet-server
    yum install telnet-server
    yum list xinetd
    yum install xinetd
    
    #启动telnet服务
    systemctl enable xinetd
    systemctl enable telnet.socket
    systemctl start telnet.socket
    systemctl start xinetd
    
    #默认情况下系统是不允许root用户telnet远程登录的
    #如果要使用root用户直接登录需设置/etc/securetty
    vim /etc/securetty
    #添加 pts/0 
    #添加 pts/1
    systemctl restart xinetd
    
    #root登录时总是提示 login incorrect
    vim /etc/pam.d/login
    #auth ****** pam_securetty.so    注释这行
    
    #设置好后,最好重启下服务器
    reboot
    systemctl start telnet.socket
    systemctl start xinetd
    
    #wget 下载资源包
    wget https://cdn.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.9p1.tar.gz
    
    #安装依赖包
    yum install openssl openssl-devel pam-devel gcc gcc-c++ zlib zlib-devel zlib-static
    
    #解压openssh-7.9p1.tar.gz
    tar -zxvf openssh-7.9p1.tar.gz
    cd openssh-7.9p1
    
    #备份/etc/ssh
    mv /etc/ssh /opt/ssh.bak
    
    #安装openssh7.9
    ./configure --sysconfdir=/etc/ssh
    #没有错误继续
    make && make install
    
    #查看版本
    /usr/local/sbin/sshd -v

    #编译安装完毕后,默认不允许root远程登录
    vim /etc/ssh/sshd_config
    #PermitRootLogin prohibit-password 改成 PermitRootLogin yes
    
    #重启sshd
    systemctl restart sshd
    systemctl stop sshd
    systemctl start sshd
    systemctl enable sshd
    
    #可以关闭下sshd来体验下telnet,登录telnet后台启动下sshd
